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…
Floquet Reservoir Engineering for Remote Logical Entanglement
Mingxing Yao, Aashish A. Clerk
Implementing controlled dissipative dynamics is a powerful approach for state preparation in a variety of contexts, including the preparation of remote entangled states. Here, we s…
Symmetry as a route to generalized bosonic Kitaev chains
Gideon Lee, Tony Jin, Aashish A. Clerk
The bosonic Kitaev chain (BKC) model is a deceptively simple looking quadratic pairing Hamiltonian. Despite being purely Hermitian, it exhibits a number of striking non-Hermitian t…
Exact metastability in a class of driven-dissipative quantum many-body systems
David D. Noachtar, Aashish A. Clerk
Metastability in many-body quantum systems and its associated exponentially-long timescales have been the subject of considerable recent interest. Here, we focus on a class of driv…
Exact steady states of interacting driven dissipative fermionic systems with hidden time-reversal symmetry
Andrew Lingenfelter, Aashish A. Clerk
We present exact solutions for the non-equilibrium steady states of a class of dissipative spinless fermionic systems with arbitrary Hamiltonian pairing terms, global charging ener…
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…
