Quantum spin probe of single charge dynamics
Jonathan C. Marcks, Mykyta Onizhuk, Yu-Xin Wang +9
Electronic defects in semiconductors form the basis for many emerging quantum technologies. Understanding defect spin and charge dynamics in solid state platforms is crucial to dev…
Understanding central spin decoherence due to interacting dissipative spin baths
Mykyta Onizhuk, Yu-Xin Wang, Jonah Nagura +2
We propose a new approach to simulate the decoherence of a central spin coupled to an interacting dissipative spin bath with cluster-correlation expansion techniques. We benchmark…
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…
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…
Entanglement phase transition due to reciprocity breaking without measurement or post-selection
Gideon Lee, Tony Jin, Yu-Xin Wang +2
Despite its fully unitary dynamics, the bosonic Kitaev chain (BKC) displays key hallmarks of non-Hermitian physics including non-reciprocal transport and the non-Hermitian skin eff…
Guiding Diamond Spin Qubit Growth with Computational Methods
Jonathan C. Marcks, Mykyta Onizhuk, Nazar Delegan +7
The nitrogen vacancy (NV) center in diamond, a well-studied, optically active spin defect, is the prototypical system in many state of the art quantum sensing and communication app…
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…
Detecting spin bath polarization with quantum quench phase shifts of single spins in diamond
Paul C. Jerger, Yu-Xin Wang, Mykyta Onizhuk +7
Single-qubit sensing protocols can be used to measure qubit-bath coupling parameters. However, for sufficiently large coupling, the sensing protocol itself perturbs the bath, which…
