Breaking conservation law enables steady-state entanglement out of equilibrium
Vince Hou, Eric Kleinherbers, Shane P. Kelly +1
We show how entangled steady states can be prepared by purely dissipative dynamics in a system coupled to a thermal environment. While entanglement is hindered by thermalization wh…
Nanoscale observation and control of quasiparticle induced magnetic noise in a superconducting resonator
Senlei Li, Shane P. Kelly, Jingcheng Zhou +4
Superconducting circuits are arguably taking a leading role in driving the ongoing quantum technological revolution. A detailed knowledge of the microscopic fluctuating electromagn…
Entangling color centers via magnon-antimagnon pair creation
Eric Kleinherbers, Shane P. Kelly, Yaroslav Tserkovnyak
We present how entanglement between a spatially separated pair of color centers can be created by letting them weakly interact with the quantum fluctuations of a nonequilibrium mag…
Superconductivity-enhanced magnetic field noise
Shane P. Kelly, Yaroslav Tserkovnyak
We consider the stray magnetic field noise outside a two-dimensional superconductor. Our considerations are motivated by recent experiments, which observed an enhancement in the ma…
Correlated emission of electron-current waves
Shane P. Kelly, Eric Kleinherbers, Yanyan Zhu +1
Correlated emission of light offer a potential avenue for entanglement generation between atomic spins, with potential application for sensing and quantum memory. In this work, we…
Pseudo-Hermitian physics from dynamically coupled macrospins
Peter Connick, Shane P. Kelly, Yaroslav Tserkovnyak
We consider two classical macrospins with dynamical (frequency-dependent) coupling, modeled by a generalized Landau-Lifshitz-Gilbert equation. We show that, in the absence of local…
