Observable Estimation in the Absence of Classical Verification
Samantha V. Barron, Bradley Mitchell, Vinay Tripathi +45
The paper proposes a framework to independently validate observable estimates from quantum computers when classical benchmarks are unavailable, using experiments such as the operat…
Resolving Structure in Prethermal Floquet Dynamics with Precision Quantum Computation
Eyal Leviatan, Tasneem Watad, Roy Perry +38
Periodically driven interacting quantum many-body systems can exhibit long-lived prethermal dynamics, where local observables retain coherent structure even as entanglement and ope…
Correlated Coherent Errors in Stabilizer Codes: A General Cumulant Framework and Interference-Based Error Suppression
Rohan N Rajmohan, Antoine Brillant, Peter Groszkowski +3
Coherent errors in stabilizer codes are often correlated across qubits and QEC cycles. Having a general analytical treatment of such noise would thus be extremely valuable. We deri…
Noise Correlations as a Resource in Pauli-Twirled Circuits
Antoine Brillant, Rohan N Rajmohan, Peter Groszkowski +3
Randomized compiling (RC) is an established tool to tailor arbitrary quantum noise channels into Pauli errors. The effect of both spatial and temporal noise correlations in randoml…
Single snapshot non-Markovianity of Pauli channels
Alireza Seif, Moein Malekakhlagh, Swarnadeep Majumder +1
Pauli channels are widely used to describe errors in quantum computers, particularly when noise is shaped via Pauli twirling. A common assumption is that such channels admit a Mark…
Signatures of Quantum Phase Transitions in Driven Dissipative Spin Chains
Mostafa Ali, Naushad A. Kamar, Alireza Seif +1
Open driven quantum systems have defined a powerful paradigm of nonequilibrium phases and phase transitions; however, quantum phase transitions are generically not expected in this…
