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…
Randomized benchmarking with non-Markovian noise and realistic finite-time gates
Antoine Brillant, Peter Groszkowski, Alireza Seif +2
We analyze the impact of non-Markovian classical noise on single-qubit randomized benchmarking experiments, in a manner that explicitly models the realization of each gate via real…
Orthogonal polynomials and the deformed Jordan plane
André Beaudoin, Geoffroy Bergeron, Antoine Brillant +3
We consider the unital associative algebra with two generators , obeying the defining relation .…
