Hardware-Efficient Erasure Qubits With Superconducting Transmon Qutrits
Bao-Jie Liu, Ying-Ying Wang, Yu-Xin Wang +3
Quantum error correction using erasure qubits offers higher fault-tolerant thresholds and improved scaling by converting dominant physical errors into detectable erasures. In super…
Uncovering measurement-induced entanglement via directional adaptive dynamics and incomplete information
Yu-Xin Wang, Alireza Seif, Aashish A. Clerk
The rich entanglement dynamics and transitions exhibited by monitored quantum systems typically only exist in the conditional state, making observation extremely difficult. In this…
Measurement and feedforward induced entanglement negativity transition
Alireza Seif, Yu-Xin Wang, Ramis Movassagh +1
We study the interplay between measurement-induced dynamics and conditional unitary evolution in quantum systems. We numerically and analytically investigate commuting random measu…
Exact Results for a Boundary-Driven Double Spin Chain and Resource-Efficient Remote Entanglement Stabilization
Andrew Lingenfelter, Mingxing Yao, Andrew Pocklington +4
We derive an exact solution for the steady state of a setup where two -coupled -qubit spin chains (with possibly non-uniform couplings) are subject to boundary Rabi drives,…
Dispersive Non-reciprocity between a Qubit and a Cavity
Ying-Ying Wang, Yu-Xin Wang, Sean van Geldern +3
The dispersive interaction between a qubit and a cavity is ubiquitous in circuit and cavity quantum electrodynamics. It describes the frequency shift of one quantum mode in respons…
