Observation and Modulation of the Quantum Mpemba Effect on a Superconducting Quantum Processor
Yueshan Xu, Cai-Ping Fang, Bing-Jie Chen +33
In non-equilibrium quantum systems, the quantum Mpemba effect (QME) emerges as a counterintuitive phenomenon: systems exhibiting greater initial symmetry breaking restore symmetry…
Flexible Readout and Unconditional Reset for Superconducting Multi-Qubit Processors with Tunable Purcell Filters
Yong-Xi Xiao, Da'er Feng, Xu-Yang Gu +18
Achieving high-fidelity qubit readout and reset while preserving qubit coherence is essential for quantum error correction and other advanced quantum algorithms. Here, we design an…
Multimode Purcell Filter for Superconducting-Qubit Reset and Readout with Intrinsic Purcell Protection
Xu-Yang Gu, Da'er Feng, Zhen-Yu Peng +17
Efficient qubit reset and leakage reduction are essential for scalable superconducting quantum computing, particularly in the context of quantum error correction. However, such ope…
Tuning the Quantum Mpemba Effect in Isolated System by Initial State Engineering
Yihan Yu, Tianren Jin, Lv Zhang +2
We investigate the quantum Mpemba effect (QME) in isolated, non-integrable quantum systems, where relaxation dynamics depend on structure of the initial states. By analyzing the di…
Microwave Engineering of Tunable Spin Interactions with Superconducting Qubits
Kui Zhao, Ziting Wang, Yu Liu +24
Quantum simulation has emerged as a powerful framework for investigating complex many - body phenomena. A key requirement for emulating these dynamics is the realization of fully c…
Markov Gap and Bound Entanglement in Haar Random State
Tian-Ren Jin, Shang Liu, Heng Fan
Bound entanglement refers to entangled states that cannot be distilled into maximally entangled states and therefore cannot directly be used in many quantum information processing…
