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…

Protomon: A Multimode Qubit in the Fluxonium Molecule
Shashwat Kumar, Xinyuan You, Xanthe Croot +7
Qubits that are intrinsically insensitive to depolarization and dephasing errors promise to significantly reduce the overhead of fault-tolerant quantum computing. At their optimal…
