QuEra’s neutral-atom architecture combines high coherence, flexible connectivity, and scalability. I will present recent progress toward fault-tolerant quantum computation, highlighting our logical processor based on reconfigurable atom arrays and advances in error correction demonstrated with academic partners. The talk will also touch on the integration of QuEra’s digital platform Gemini...

The Unruh effect predicts that a uniformly accelerated observer in the Minkowski vacuum perceives a thermal bath, so that an accelerating detector behaves as an open quantum system interacting with an effective thermal environment. We exploited this perspective to study entanglement generation between two identical two-level atoms located at the same spacetime point and weakly coupled to the...

Complex quantum systems—composed of many, interacting particles—are intrinsically difficult to model. When a quantum many-body system is subject to disorder, it can undergo transitions to regimes with varying non-ergodic and localized behavior, which can significantly reduce the number of relevant basis states.

It remains an open question whether such transitions are also directly related... -

In this talk, we investigate multipartite entanglement through the statistical properties of pure quantum states of $n$-qubits. By analyzing the distribution of purity among balanced bipartitions, we will compare Haar-typical states with the so called Hadamard states, the latter being characterized by equal weights in the computational basis. We analyze different classes of Hadamard states...

We derive the Fubini–Study metric, which endows the manifold of multi-qubit quantum states with a Riemannian structure.

We then explore the deep relationship between this Riemannian structure—defined on the projective Hilbert space of the system—and the entanglement properties of the states it contains.
Thus, we derived a measure of entanglement, the Entanglement Distance (ED), a quantity... -

We investigate multipartite entanglement in a specific class of pure n-qubit quantum states, the uniform real-phased states referred to as Hadamard states, through a statistical mechanics framework, where the average bipartite purity maps onto an effective Hamiltonian of $2^n$ binary classical spins. In this correspondence, each Hadamard state uniquely corresponds to a classical spin...

Superconducting qubits have emerged as promising platforms for quantum sensing, including the detection of dark matter candidates that couple to photons, such as axions and hidden photons. Conventional haloscope experiments in the few-gigahertz range can be enhanced using transmon qubits to suppress dark count rates, either exploiting qubit excitation schemes [1] or Quantum Non-Demolition...

As quantum devices progress towards a quantum advantage regime, they become harder to benchmark. A particularly relevant challenge is to assess the quality of the whole computation, beyond testing the performance of each single operation. I will introduce a scheme for this task that combines the target computation with variants of it, which, when averaged, allow for classically solvable...

Floquet theory is a general method that allows one to treat linear systems of differential equations with periodic generators. It decomposes the propagator associated with the dynamical evolution into two parts: one associated with the micromotion within a period, and another corresponding to the effective stroboscopic propagation after each period. This framework is widely used in closed...
