Quantum Zeno and anti-Zeno effects in open quantum systems
Zixian Zhou, Zhiguo Lü, Hang Zheng +1
Traditional approach on quantum Zeno effect (QZE) and quantum anti-Zeno effect (QAZE) in open quantum systems (implicitly) assumes the bath (environment) state returning to its ori…
Thermodynamic description of non-Markovian information flux of nonequilibrium open quantum systems
Hong-Bin Chen, Guang-Yin Chen, Yueh-Nan Chen
One of the fundamental issues in the field of open quantum systems is the classification and quantification of non-Markovianity. In the contest of quantity-based measures of non-Ma…
Work extraction and fully entangled fraction
Chung-Yun Hsieh, Ray-Kuang Lee
For a bipartite state with equal local dimension d, we prove that one can obtain work gain under Landauer's erasure process on one party in identically and independently distribute…
Universal measurement-based quantum computation in two-dimensional SPT phases
Tzu-Chieh Wei, Ching-Yu Huang
Recent progress in characterization for gapped quantum phases has also triggered the search of universal resource for quantum computation in symmetric gapped phases. Prior works in…
Bell's Inequality and Entanglement in Qubits
Po-Yao Chang, Su-Kuan Chu, Chen-Te Ma
We propose an alternative evaluation of quantum entanglement by measuring the maximum violation of the Bell's inequality without performing a partial trace operation. This proposal…
Robust quantum gates for stochastic time-varying noise
Chia-Hsien Huang, Hsi-Sheng Goan
How to effectively construct robust quantum gates for time-varying noise is a very important but still outstanding problem. Here we develop a systematic method to find pulses for q…
