Many-body quantum chaos and time reversal symmetry

Weijun Wu, Saumya Shivam, Amos Chan

We investigate universal signatures of quantum chaos in the presence of time reversal symmetry (TRS) in generic many body quantum chaotic systems (gMBQCs). We study three classes o…

Utility of virtual qubits in trapped-ion quantum computers

Saumya Shivam, Fabian Pokorny, Andres Vazquez-Brennan +5

We propose encoding multiple qubits inside ions in existing trapped-ion quantum computers to access more qubits and to simplify circuits implementing standard algorithms. By using…

Many-body quantum chaos and emergence of Ginibre ensemble

Saumya Shivam, Andrea De Luca, David A. Huse +1

We show that non-Hermitian Ginibre random matrix behaviors emerge in spatially-extended many-body quantum chaotic systems in the space direction, just as Hermitian random matrix be…

On Classical and Hybrid Shadows of Quantum States

Saumya Shivam, C. W. von Keyserlingk, S. L. Sondhi

Classical shadows are a computationally efficient approach to storing quantum states on a classical computer for the purposes of estimating expectation values of local observables,…

Many-Body Quantum Chaos and Space-time Translational Invariance

Amos Chan, Saumya Shivam, David A. Huse +1

We study the consequences of having translational invariance in space and in time in many-body quantum chaotic systems. We consider an ensemble of random quantum circuits, composed…

Recursive contact tracing in Reed-Frost epidemic models

Saumya Shivam, Vir B. Bulchandani, S. L. Sondhi

We introduce a Reed-Frost epidemic model with recursive contact tracing and asymptomatic transmission. This generalizes the branching-process model introduced by the authors in a p…
