75. Introduction to superconducting qubits for QIS & beyond

This talk will provide a brief overview and introduction to superconducting qubits: their historical development, their current use, and future prospects.

74. History and frontiers of SRF technology and application.

Hasan Padamsee

02/09/2023, 11:30

SRF (Superconducting Radio Frequency) science and technology has taken the accelerator world by storm. Steady advances in SRF performance have enabled, and continue to enable, a large variety of SRF-based accelerators for applications in materials science, nuclear physics, nuclear astrophysics, and high energy physics. The total installed voltage has risen from 7 GeV in the year 2000 to 25 GeV...

76. Loophole-free Bell Inequality Violation with Superconducting Circuits*

Andreas Wallraff

02/09/2023, 12:00

Superposition, entanglement, and non-locality constitute fundamental features of quantum physics. Remarkably, the fact that quantum physics does not follow the principle of locality can be experimentally demonstrated in Bell tests performed on pairs of spatially separated, entangled quantum systems. While Bell tests were explored over the past 50 years, only relatively recently experiments...

23. Performance and scalability tradeoffs in a superconducting qubit processor architecture

Andrew Bestwick (Rigetti)

02/09/2023, 12:30

Rigetti Computing's QPU roadmap projects scaling to large systems by lateral tiling of many individual superconducting qubit chips in a multi-die assembly. Each chip in the assembly, meanwhile, has a dense array of qubits and tunable couplers with 3D signalling. This talk will discuss the challenges of engineering such a QPU to have long coherence times, fast control, and strong qubit-qubit...

77. The Case for Testing the Modifications of Quantum Mechanics

David Kaplan

02/09/2023, 15:00

We discuss the case for potential extensions to and motivate tests of quantum mechanics. We then argue that most extensions of quantum mechanics inherently include state-dependent time evolution. We then present a causal modification of quantum mechanics by adding non-linear (state-dependent) terms to the Schrodinger Equation. We find that, until recently, experimental bounds on these...

24. Quantum noise in interferometric gravitational wave detectors

Jean-Pierre Zendri (INFN Padova)

02/09/2023, 15:30

Quantum noise plays an important role in limiting the sensitivity of current interferometric gravitational (GW) wave detectors. For this reason, in recent years all international collaborations have undertaken an R&D campaign aimed at overcoming the Standard Quantum Limit for GW detectors. The strategy employed is based on the use of squeezed vacuum states injected in to the detector port of...
