Non-Hermitian Spin-Spin Interaction Mediated by Chiral Phonons
Haowei Xu, Guoqing Wang, Changhao Li +3
Non-Hermiticity and chirality are two fundamental properties known to give rise to various intriguing phenomena. However, the interplay between these properties has been rarely exp…
Comment on "High-Power Collective Charging of a Solid-State Quantum Battery"
Haowei Xu, Ju Li
In the Letter [Physical Review Letters 120, 117702 (2018)], Ferraro \emph{et al.} claimed a quantum advantage in the Dicke quantum battery (QB), whereby two-level systems (TLS)…
Blind quantum machine learning with quantum bipartite correlator
Changhao Li, Boning Li, Omar Amer +11
Distributed quantum computing is a promising computational paradigm for performing computations that are beyond the reach of individual quantum devices. Privacy in distributed quan…
Exponentially Enhanced non-Hermitian Cooling
Haowei Xu, Uroš Delić, Guoqing Wang +3
Certain non-Hermitian systems exhibit the skin effect, whereby the wavefunctions become exponentially localized at one edge of the system. Such exponential amplification of wavefun…
Two-photon Interface of Nuclear Spins Based on the Opto-Nuclear Quadrupolar Effect
Haowei Xu, Changhao Li, Guoqing Wang +5
Photons and nuclear spins are two well-known building blocks in quantum information science and technology. Establishing an efficient interface between optical photons and nuclear…
Laser Cooling of Nuclear Magnons
Haowei Xu, Guoqing Wang, Changhao Li +5
The initialization of nuclear spin to its ground state is challenging due to its small energy scale compared with thermal energy, even at cryogenic temperature. In this Letter, we…
Communication-efficient Quantum Algorithm for Distributed Machine Learning
Hao Tang, Boning Li, Guoqing Wang +5
The growing demands of remote detection and increasing amount of training data make distributed machine learning under communication constraints a critical issue. This work provide…
Characterizing temperature and strain variations with qubit ensembles for their robust coherence protection
Guoqing Wang, Ariel Rebekah Barr, Hao Tang +5
Solid-state spin defects, especially nuclear spins with potentially achievable long coherence times, are compelling candidates for quantum memories and sensors. However, their curr…
