Noise tailoring for error mitigation and for diagnozing digital quantum computers
Thibault Scoquart, Hugo Perrin, Kyrylo Snizhko
Error mitigation (EM) methods are crucial for obtaining reliable results in the realm of noisy intermediate-scale quantum (NISQ) computers, where noise significantly impacts output…
Gradually opening Schrödinger's box reveals a cascade of sharp dynamical transitions
Barkay Guttel, Danielle Gov, Noam Netzer +9
Quantum mechanics predicts that unobserved systems may exist in a superposition of states, yet measurement produces definite outcomes, a tension at the heart of the quantum-to-clas…
General theory of slow non-Hermitian evolution
Parveen Kumar, Yuval Gefen, Kyrylo Snizhko
Non-Hermitian systems are widespread in both classical and quantum physics. The dynamics of such systems has recently become a focal point of research, showcasing surprising behavi…
BACQ -- Application-oriented Benchmarks for Quantum Computing
Frédéric Barbaresco, Laurent Rioux, Christophe Labreuche +14
With the support of the national program on measurements, standards, and evaluation of quantum technologies MetriQs-France, a part of the French national quantum strategy, the BACQ…
Mitigating crosstalk errors by randomized compiling: Simulation of the BCS model on a superconducting quantum computer
Hugo Perrin, Thibault Scoquart, Alexander Shnirman +2
We develop and apply an extension of the randomized compiling (RC) protocol that includes a special treatment of neighboring qubits and dramatically reduces crosstalk effects cause…
