Unified trade-off optimization of quantum harmonic Otto engine and refrigerator
Varinder Singh, Satnam Singh, Obinna Abah +1
We investigate quantum Otto engine and refrigeration cycles of a time-dependent harmonic oscillator operating under the conditions of maximum -function, a trade-off objective fu…
Quantum cryptographic resource distillation and entanglement
Minjin Choi, Soojoon Lee
We look into multipartite quantum states on which quantum cryptographic protocols including quantum key distribution and quantum secret sharing can be perfectly performed, and defi…
Locking Multi-laser Frequencies to a Precision Wavelength Meter: Application to Cold Atoms
Junwoo Kim, Keumhyun Kim, Dowon Lee +6
We herein report a simultaneous frequency stabilization of two 780-nm external cavity diode lasers using a precision wavelength meter (WLM). The laser lock performance is character…
Operator Delocalization in Quantum Networks
Joonho Kim, Jeff Murugan, Jan Olle +1
We investigate the delocalization of operators in non-chaotic quantum systems whose interactions are encoded in an underlying graph or network. In particular, we study how fast ope…
Quantum Charging Advantage Cannot Be Extensive Without Global Operations
Ju-Yeon Gyhm, Dominik Šafránek, Dario Rosa
Quantum batteries are devices made from quantum states, which store and release energy in a fast and efficient manner, thus offering numerous possibilities in future technological…
Detection of quantum phase transition in spin-1 chain through multipartite high-order correlations
Dongkeun Lee, Adel Sohbi, Wonmin Son
We design a Bell inequality that is violated by correlations obtained from the ground states of XXZ spin-1 chain with on site anisotropies at the region of phase transition. In ord…
