Comment on "Loss-Free Excitonic Quantum Battery"
A. Tejero, J. Thingna, D. Manzano
In Ref. [J. Liu, D. Segal, and G. Hanna. J. Phys. Chem. C, 123, 18303 (2019)] there is a novel proposal of a quantum battery based on environmental interaction. The system studied…
Quantum transient heat transport in the hyper-parametric oscillator
JungYun Han, Daniel Leykam, Dimitris G. Angelakis +1
We explore nonequilibrium quantum heat transport in nonlinear bosonic systems in the presence of a non-Kerr-type interaction governed by hyper-parametric oscillation due to two-pho…
Bell-type correlation at quantum phase transitions in spin-1 chain
Dongkeun Lee, Wonmin Son
For the identification of non-trivial quantum phase, we exploit a Bell-type correlation that is applied to the one-dimensional spin-1 XXZ chain. It is found that our generalization…
Local invariants of braiding quantum gates -- associated link polynomials and entangling power
Pramod Padmanabhan, Fumihiko Sugino, Diego Trancanelli
For a generic -qubit system, local invariants under the action of characterize non-local properties of entanglement. In general, such properties a…
Quantum state rotation: Circularly transferring quantum states of multiple users
Yonghae Lee, Hayata Yamasaki, Soojoon Lee
Quantum state exchange is a quantum communication task for two users in which the users faithfully exchange their respective parts of an initial state under the asymptotic scenario…
Genuine Secret-Sharing States
Minjin Choi, Soojoon Lee
Quantum secret sharing allows each player to have classical information for secret sharing in quantum mechanical ways. In this work, we construct a class of quantum states on which…
