Symmetries of Pauli Noise from Lindbladian Dynamics
Moein Malekakhlagh, Edward H. Chen, Luke C. G. Govia +1
Characterizing noise in quantum circuits is fundamentally limited by gauge degrees of freedom; certain parameters, such as the individual contributions of state preparation and mea…
Disambiguating Pauli noise in quantum computers
Edward H. Chen, Senrui Chen, Laurin E. Fischer +7
To successfully perform quantum computations, it is often necessary to first accurately characterize the noise in the underlying hardware. However, it is well known that fundamenta…
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…
Quantum Enhanced Pauli Propagation
S. Majumder, J. R. Garrison, L. Luo +8
Accurately estimating observables on noisy quantum devices remains a central challenge for near-term quantum algorithms. While quantum error mitigation techniques can reduce noise-…
Order from chaos with adaptive circuits on quantum hardware
Bibek Pokharel, Haining Pan, Kemal Aziz +8
Programmable quantum devices provide a platform to control the coherent dynamics of quantum wavefunctions. Here we experimentally realize adaptive monitored quantum circuits, which…
Error mitigation with stabilized noise in superconducting quantum processors
Youngseok Kim, Luke C. G. Govia, Andrew Dane +10
Pre-fault tolerant quantum computers have already demonstrated the ability to estimate observable values accurately, at a scale beyond brute-force classical computation. This has b…
