Impact of Josephson junction array modes on fluxonium readout
Shraddha Singh, Gil Refael, Aashish Clerk +1
Dispersive readout of superconducting qubits is often limited by readout-drive-induced transitions between qubit levels. While there is a growing understanding of such effects in t…
Hardware-efficient quantum error correction via concatenated bosonic qubits
Harald Putterman, Kyungjoo Noh, Connor T. Hann +118
In order to solve problems of practical importance, quantum computers will likely need to incorporate quantum error correction, where a logical qubit is redundantly encoded in many…
Accelerating Dissipative State Preparation with Adaptive Open Quantum Dynamics
Andrew Pocklington, Aashish A. Clerk
A wide variety of dissipative state preparation schemes suffer from a basic time-entanglement tradeoff: the more entangled the steady state, the slower the relaxation to the steady…
Hidden time-reversal in driven XXZ spin chains: exact solutions and new dissipative phase transitions
Mingxing Yao, Andrew Lingenfelter, Ron Belyansky +2
We show that several models of interacting XXZ spin chains subject to boundary driving and dissipation possess a subtle kind of time-reversal symmetry, making their steady states e…
Non-Gaussian generalized two-mode squeezing: applications to two-ensemble spin squeezing and beyond
Mikhail Mamaev, Martin Koppenhöfer, Andrew Pocklington +1
Bosonic two-mode squeezed states are paradigmatic entangled Gaussian states that have wide utility in quantum information and metrology. Here, we show that the basic structure of t…
