DESCRIPTION:Speakers: Johann Marton (Stefan Meyer Institute)\nThe Pauli Ex
clusion Principle (PEP) and its connection to the spin-statistics theorem
is a empirically very well proved in fermionic systems. However\, from the
oretical considerations there are speculations about possible violations i
n the lepton sector\, i.e. for neutrinos\, which would have severe consequ
ences for cosmology. In an experiment at the Gran Sasso Laboratory (LNGS-I
NFN) we are searching for the limit of the validity of PEP for leptons by
searching PEP-forbidden electron transitions in a high-sensitivity experim
ent VIP2. The underlying concept of this experiment\, preliminary results
and an outlook for the next steps will be given.\n\nhttps://agenda.infn.it

DESCRIPTION:Speakers: Jerome Martin (CNRS)\nAccording to cosmic inflation\
, the inhomogeneities in our universe are of quantum mechanical origin. Th
is scenario was recently spectacularly confirmed by the data obtained by t
he European Space Agency (ESA) Planck satellite. In fact\, cosmic inflatio
n represents the unique situation in Physics where quantum mechanics and g
eneral relativity are needed to establish the predictions of the theory an
d where\, at the same time\, we have high accuracy data at our disposal to
test the resulting framework. So inflation is not only aphenomenologicall
y very appealing theory but it is also an ideal playground to discuss deep
questions in a cosmological context. In this talk\, I review and discuss
those quantum-mechanical aspects of inflation. In particular\, I explain w
hy inflationary quantum perturbations represent a system which is very sim
ilar to systems found in quantum optics. But I also point out the limitat
ion of this approach and investigate whetherthe large squeezing of the per
turbations can allow us to observe a genuine observational signature in th
e sky of the quantum origin of the cosmological fluctuations.\n\nhttps://a

DESCRIPTION:Speakers: Matteo Brunelli (Queen's University Belfast)\nIn thi
s talk I will apply the formalism of quantum estimation theory to extract
information about potential collapse mechanisms of the continuous spontane
ous localisation (CSL) form. The strength with which the field responsible
for the CSL mechanism couples to massive systems is estimated through the
optomechanical interaction between a mechanical resonator and a cavity fi
eld. In particular I will focus on all-optical measurements\, such as homo
dyne and heterodyne measurements\, given their practical feasibility. The
performances of such strategies are also compared with those of a spin-ass
isted optomechanical system\, where the estimation of the CSL parameter is
performed through time-gated spin-like measurements.\n\nhttps://agenda.in

quantum entanglement is created between two such objects due to their inte

tum entity. In this talk I first show that the states of two micrometer di
mension test masses in adjacent matter-wave interferometers could be detec
tably entangled solely through their mutual gravitational interaction. I t
hen argue that the purely gravitational mechanism for this entanglement im
plies that witnessing it is equivalent to certifying the quantum nature of
the gravitational field that mediates the entanglement.\n\nhttps://agenda

DESCRIPTION:Speakers: Kristian Piscicchia (LNF)\nCollapse models are pheno
menological models introduced to solve the measurement problem of quantum
mechanics and describe the transition from the quantum to the classical re
gime\; among them\, one of the most relevant and well studied is known as
Continuous Spontaneous Localization (CSL). According to this model\, the l
inear and unitary Schroedinger dynamics is modified by adding a non-linear
term and the interaction with a stochastic noise field. These modificatio
ns account for the localization of the macroscopic objects\, leaving unch
anged the dynamics at microscopic level\, but also require the introductio
n of two phenomenological parameters\, a collapse rate parameter ($\\lambd
a$) and a correlation length ($r_C$). \n The interaction with the stoch
astic field causes an extra emission of electromagnetic radiation for char
ged particles\, which is not predicted by the standard quantum mechanics\,
known as spontaneous radiation emission. We will show that comparing the
X-ray emission measured with ultra-pure Germanium detectors with the expec
ted spontaneous radiation spectrum allows to obtain the most stringent lim
its on $\\lambda$ and $r_C$ on a broad range of the parameters space.\n\nh

DESCRIPTION:Speakers: Caslav Brukner (University of Vienna)\nThe Einstein
Equivalence Principle (EEP) enables understanding gravity as space-time ge
ometry. The principle requires equivalence between the rest\, inertial and
gravitational mass-energies. However\, in quantum mechanics\, even non-re
lativistic\, quantized internal energies contribute to the total mass-ener
gies. In the talk I will introduce a “quantum formulation of the weak EE
P” as the equivalence between the rest\, inertial and gravitational inte
rnal energy operators. Importantly\, validity of the classical EEP does no
t imply the validity of its quantum formulation\, which requires an indepe
ndent experimental verification. I will explore the ways to test the quant
um EEP.\n\nhttps://agenda.infn.it/event/13169/contributions/18112/

DESCRIPTION:Speakers: Pawel Moskal (Jagiellonian University)\nIf the Natur
e was utterly symmetric the matter would not exist. Yet\, processes driven
by the gravitational\, electromagnetic and strong interactions seem to be
symmetric with respect to reflection in space (P)\, reversal in time (T)
and charge conjugation (C). So far violations of these symmetries were obs
erved only in processes governed by the weak interaction. Interestingly\,
though the matter which we know is made of quarks and leptons\, violation
of CP and T symmetries have been observed only for systems including quark
s\, and it has not yet been discovered in any processes involving purely l
eptonic matter.\nPositronium is the lightest purely leptonic object decayi
ng into photons. As an atom bound by a central potential\, it is a parity
eigenstate\, and as an atom built out of an electron and an anti-electron\
, it is an eigenstate of the charge conjugation operator. The newly constr
ucted Jagiellonian Positron Emission Tomograph (J-PET) is a first PET tomo
graph built from plastic scintillators [1]\nand it enables to study the de
cays of positronium atoms [2]. Specifically it enables to perform tests of
discrete symmetries in the leptonic sector via the determination of the e
xpectation values of the discrete-symmetries-odd operators\, which may be
constructed from the spin of ortho-positronium atom and the momenta and po
larization vectors of photons originating from its annihilation. We will p
resent the potential of the J-PET detector to test the C\, CP\, T and CPT
symmetries in the decays of positronium atoms and report on the first data
-taking campaigns.\n\n[1] J-PET: P. Moskal et al.\, Nucl. Instrum. Meth. A

DESCRIPTION:Speakers: Sandro Donadi (TS)\nCollapse models are phenomenolog
ical models\, proposed to solve the measurement problem. In these models t
he Schroedinger equation is modified and the state vectors evolve accordin
g to a non-linear and stochastic dynamics. The effect of these non-linear
terms is to induce the wave function collapse in space. The dynamics is bu
ilt in such a way that the deviations from the linear Schroedinger dynamic
s are very small for microscopic systems (e.g. particles and atoms) while
they become more and more relevant when the system's size increases\, exp
laining the quantum to classical transition. The models make predictions d
ifferent from quantum mechanics hence\, they can be tested in experiments.
\nIn this talk\, I will give a general introduction to the most relevant
collapse models and their properties. Then\, I will present a summary of t
he current bounds set by different kind of experiments (macromolecule inte
rference\, radiation emission\, cantilevers\, etc..) on the parameters of
these models.\n\nhttps://agenda.infn.it/event/13169/contributions/18107/

DESCRIPTION:Speakers: Luca Curcuraci (T)\nI will present a toy model which
exhibit interesting properties from the point of view of the foundations
of quantum mechanics and probability theory.\nThe model describes a point-
like particle which moves by random jumps on a discrete random space\, tha
t is described by a collection of random walks. The particle at a certain
time t is assumed to be completely described by two quantities: its positi
on and its velocity\, which are represented by two random variables. Anoth
er random variable is the configuration of the space at the same time t. T
he model is not deterministic\, as such its description is done in terms o
f the probability distributions of these random variables.\nIt is possible
to prove that the position and the velocity of the particle at the time t
fulfil an entropic uncertainty relation\, after conditioning with respect
to the configuration space at the same time (operation that in some sense
“removes the space from the model”). Entropic uncertainty relations a
re additive uncertainty relations between the Shannon’s entropies of two
non-commuting operators. This implies that\, if we want to describe the p
osition and the velocity random variables in this model\, without any refe
rence on the space\, we have to use non-commuting operators over some Hilb
ert space. During the talk an intuitive proof of these facts will be provi
ded.\n\nhttps://agenda.infn.it/event/13169/contributions/18106/

the usual meaning of the word. So how about measurements\, in the usual me
aning of the word\, in a collapse model? For example\, if GRW theory were
true\, then how could we measure the number of collapses that have occurre
d in a given physical system in a given time interval? I provide a mathema
tical analysis of some simple cases. It turns out that there are limitatio
ns to knowledge---that is\, that some well-defined quantities cannot be re
liably measured empirically. Such a situation may seem philosophically pro

DESCRIPTION:Speakers: Giuseppe Antonio Nistico' (CS)\nIn Quantum Physics v
ery rarely it happens that the value of an observable is obtained by a 'di
rect' measurement. In fact\, in almost all cases\, such a value is assigne
d by measuring another observable characterized by perfect correlation wit
h the observable of interest\, and then assigning it the value according
to the correlation. The assignment of the value of the spin observable to
a silver atom through a Stern and Gerlach apparatus is an effective exampl
e\, where the value assignment\, inferred from the exit localization (up o
r down)\, is often identified with an authentic measurement of the spin.\n
Given the importance of the concept of measurements and of the role they
play in the investigation about the foundational problems of Quantum Theo
ry\, such as the measurement problem\, contextuality\, locality\, the task
s of precisely establishing the conceptual and formal status of these valu
e assignments (we shall call 'evaluations') and of establishing how they a
re related to \nauthentic measurement cannot be overlloked by Quantum Theo
ry.\n In this talk\, once demonstrated that evaluations cannot be identif
ied with measurements\, we single out the conditions under which an evalua
tion is a perfect simulation of the corresponding measurement.\n However\
, evaluations are allowed also when these conditions are notsatisfied. The
n we identify the domains of circumstances\, i.e. determined domains of ob
servables\, where assignment by evaluation is consistent with measurement.

DESCRIPTION:Speakers: Kyrylo Simonov (University of Vienna)\nThe measureme
nt problem reveals one of the conceptual difficulties the quantum theory m
eets despite its extreme success. Why do we not observe a table or a cat i
n two places at the same time? A microscopic system is in a superposition:
in which way is it broken up while we perform a measurement on the system
? What is a measurement apparatus? So-called models of spontaneous collaps
e (collapse models) claim to provide an answer to these questions through
a powerful and mathematically complete approach which models the collapse
of the wave function as an objective physical process. These models featur
e an important property\, namely they can be excluded in plethora of exper
iments\, for example\, tests by X-rays\, optomechanical systems\, cold-ato
m experiments and others. In this talk we present a study of the two popul
ar models of spontaneous collapse at high energy scale\, i.e. within flavo
r oscillating neutral mesons which are superpositions of two different mas
s-eigenstates. We show how these systems contribute to the testing of coll
apse models constraining the possible collapse scenarios by experimental d
ata and propose a new interpretation of the decay mechanism of neutral mes
ons via spontaneous collapse.\n\nhttps://agenda.infn.it/event/13169/contri

SUMMARY:On a correspondence between Trace Dynamics and Quantum Theories

DESCRIPTION:Speakers: Stefano Bacchi (T)\nAbstract. Trace Dynamics (TD) is
a pre-quantum theory\, which declares to recover standard Quantum Mechani
cs (QM) by a thermodynamic-like procedure as explained in [Adl04]. TD is a
n underlying theory for spontaneous collapse models [BLS+13]\, which at pr
esent are phenomenological models for solving the quantum measurement prob
lem and the absence of macroscopic superposition. TD is a very young theor
y\, with several crucial open problems both from the theoretical physics a
s well as mathematical physics point of view\, we explain here the main is
sues. In order to obtain QM from TD\, one needs an average procedure on th
e Grassmann algebraic space over which TD lies\; so we specify the mathema
tical details of this procedure. We evolve the space of TD into a super Hi
lbert space and we proof the existence of a well-defined relation between
the super Hilbert space of TD and a standard Hilbert space. Moreover we ma
ke explicit what are the constraints in order to derive a rigorous corresp
ondence between TD and Quantum Field Theory.\n\nReferences. \n[Adl04] S.L.

DESCRIPTION:Speakers: Rainer Kaltenbaek (University of Vienna\, Vienna Cen
ter for Quantum Science and Technology\, Faculty of Physics)\nTremendous p
rogress has been made in space technology over the last decades. This tech
nological heritage promises enabling applications of quantum technology in
space already now or in the near future. Heritage in laser and optical te
chnologies from LISA Pathfinder comprises core technologies required for q
uantum optical experiments. Low-noise micro-thruster technology from GAIA
allows achieving impressive microgravity levels\, and passive as well as a
ctive cryogenic cooling has been harnessed in a harnessed in missions rang
ing from Planck to the James Webb Space Telescope and may be adapted for t
he requirements of quantum experiments. Developments like these have rende
red space an increasingly attractive platform for quantum-enhanced sensing
and for fundamental tests of physics using quantum technology. In particu
lar\, there already have been significant efforts towards realizing atom i
nterferometry and atomic clocks in space as well as efforts to harness spa
ce as an environment for fundamental tests of physics using quantum optome
chanics and high-mass matter-wave interferometry. Here\, we will present r
ecent efforts in mission planning\, spacecraft design and technology devel
opment towards this latter goal in the context of the mission proposal MAQ
RO and ESA's recent call for New Science Ideas.\n\nhttps://agenda.infn.it/

DESCRIPTION:Speakers: Giuseppina Modestino (LNF)\nStarting from a reinterp
retation of the inverse quadratic law that spatially describes a gravitati
onal field\, we come to formulas compatible and easily testable with celes
tial mechanics. The same formulas apply a similar hypothesis to a system o
f Bohr radius size dimensions\, obtaining a stable structure\, while not i
ntroducing quantum mechanics. The validity of this hypothesis is all to be
demonstrated\, and for this a more accurate comparison is required\, both
with experimental measurements and just with quantum mechanics theory\n\n

DESCRIPTION:Speakers: Samuel McMillen (Queen's University Belfast)\nWe app
ly the formalism of hypothesis testing to the detection of the continuous
spontaneous localisation (CSL) model. The testbed consists of a cavity opt
omechanical system: the collapse mechanism acts as an additional heating o
f the mechanical resonator\, thereby indirectly affecting the cavity field
on which we can perform measurements. Initialresults are based on discrim
ination between two squeezed thermal states with different temperatures. W
e calculate the asymptotic error\nprobabilities associated with a classica
l statistical test\, using all-optical homodyne measurements\, and compare
the results with the quantum Chernoff bound.\n\nhttps://agenda.infn.it/ev
