Universal distributed blind quantum computing with solid-state qubits

Yan-Cheng Wei, Pieter-Jan Stas, Aziza Suleymanzade +16

Blind quantum computing (BQC) is a promising application of distributed quantum systems, where a client can perform computations on a remote server without revealing any details of…

Emergent disorder and sub-ballistic dynamics in quantum simulations of the Ising model using Rydberg atom arrays

Ceren B. Dag, Hanzhen Ma, P. Myles Eugenio +2

Rydberg atom arrays with Van der Waals interactions provide a controllable path to simulate the locally connected transverse-field Ising model (TFIM), a prototypical model in stati…

Spatial averaging for light reflection and transmission through cold atom arrays

F. Robicheaux

We theoretically and computationally investigate the role that the spatial spread of atoms plays in the transmission and reflection of weak light from atom arrays. In particular, w…

Many-body adiabatic passage: Instability, chaos, and quantum classical correspondence

Anant Vijay Varma, Amichay Vardi, Doron Cohen

Adiabatic passage in systems of interacting bosons is substantially affected by interactions and inter-particle entanglement. We consider STIRAP-like schemes in Bose-Hubbard chains…

Genuine quantum scars in many-body spin systems

Andrea Pizzi, Long-Hei Kwan, Bertrand Evrard +2

Chaos makes isolated systems of many interacting particles quickly thermalize and forget about their past. Here, we show that quantum mechanics hinders chaos in many-body systems:…

Hamiltonian and Liouvillian learning in weakly-dissipative quantum many-body systems

Tobias Olsacher, Tristan Kraft, Christian Kokail +2

We discuss Hamiltonian and Liouvillian learning for analog quantum simulation from non-equilibrium quench dynamics in the limit of weakly dissipative many-body systems. We present…

Measuring Spectral Form Factor in Many-Body Chaotic and Localized Phases of Quantum Processors

Hang Dong, Pengfei Zhang, Ceren B. Dag +28

The spectral form factor (SFF) captures universal spectral fluctuations as signatures of quantum chaos, and has been instrumental in advancing multiple frontiers of physics includi…

Characterization of hybrid quantum eigenstates in systems with mixed classical phasespace

Anant Vijay Varma, Amichay Vardi, Doron Cohen

Generic low-dimensional Hamiltonian systems feature a structured, mixed classical phase-space. The traditional Percival classification of quantum spectra into regular states suppor…

Enhancing a Many-body Dipolar Rydberg Tweezer Array with Arbitrary Local Controls

Guillaume Bornet, Gabriel Emperauger, Cheng Chen +8

We implement and characterize a protocol that enables arbitrary local controls in a dipolar atom array, where the degree of freedom is encoded in a pair of Rydberg states. Our appr…

Long-lived topological time-crystalline order on a quantum processor

Liang Xiang, Wenjie Jiang, Zehang Bao +38

Topologically ordered phases of matter elude Landau's symmetry-breaking theory, featuring a variety of intriguing properties such as long-range entanglement and intrinsic robustnes…
