Extracting Error Thresholds through the Framework of Approximate Quantum Error Correction Condition
Yuanchen Zhao, Dong E. Liu
The robustness of quantum memory against physical noises is measured by two methods: the exact and approximate quantum error correction (QEC) conditions for error recoverability, a…
Optimal energy storage in the Tavis-Cummings quantum battery
Hui-Yu Yang, Hai-Long Shi, Qing-Kun Wan +3
The Tavis-Cummings (TC) model, which serves as a natural physical realization of a quantum battery, comprises atoms as battery cells that collectively interact with a shared…
Passive and Deterministic Controlled-phase Gate for Single-photon Wavepackets Based on Time-reversal Symmetric Photon Transport
Zhaohua Tian, Xue-Wen Chen
We report the construction of a passive, deterministic and near-unity-fidelity controlled--phase gate for single-photon wavepackets with a node comprising a two-level emitter an…
Joint Estimation of a Two-Phase Spin Rotation beyond Classical Limit
Jiahao Cao, Xinwei Li, Tianwei Mao +2
Quantum metrology employs entanglement to enhance measurement precision. The focus and progress so far have primarily centered on estimating a single parameter. In diverse applicat…
Locally purified density operators for noisy quantum circuits
Yuchen Guo, Shuo Yang
Simulating open quantum systems is essential for exploring novel quantum phenomena and evaluating noisy quantum circuits. In this Letter, we address the problem of whether mixed st…
Recovery of damaged information via scrambling in indefinite casual order
Tian-Ren Jin, Tian-Ming Li, Zheng-An Wang +3
Scrambling prevents the access to local information with local operators and therefore can be used to protect quantum information from damage caused by local perturbations. Even th…
