Experimental Validation of Enhanced Information Capacity by Quantum Switch in Accordance with Thermodynamic Laws
Cheng Xi, Xiangjing Liu, Hongfeng Liu +6
We experimentally probe the interplay of the quantum switch with the laws of thermodynamics. The quantum switch places two channels in a superposition of orders and may be applied…
Self-Consistent Determination of Single-Impurity Anderson Model Using Hybrid Quantum-Classical Approach on a Spin Quantum Simulator
Xinfang Nie, Xuanran Zhu, Yu-ang Fan +9
The accurate determination of the electronic structure of strongly correlated materials using first principle methods is of paramount importance in condensed matter physics, comput…
Reversing Heat Flow by Coherence in a Multipartite Quantum System
Keyi Huang, Qi Zhang, Xiangjing Liu +12
The second law of thermodynamics dictates that heat flows spontaneously from a high-temperature entity to a lower-temperature one. Yet, recent advances have demonstrated that quant…
Experimental Realization of Self-Contained Quantum Refrigeration
Keyi Huang, Cheng Xi, Xinyue Long +7
A fundamental challenge in quantum thermodynamics is the exploration of inherent dimensional constraints in thermodynamic machines. In the context of two-level systems, the most co…
Neural quantum embedding via deterministic quantum computation with one qubit
Hongfeng Liu, Tak Hur, Shitao Zhang +10
Quantum computing is expected to provide exponential speedup in machine learning. However, optimizing the data loading process, commonly referred to as quantum data embedding, to m…
Experimental Realization of a Quantum Refrigerator Driven by Indefinite Causal Orders
Xinfang Nie, Xuanran Zhu, Keyi Huang +11
Indefinite causal order (ICO) is playing a key role in recent quantum technologies. Here, we experimentally study quantum thermodynamics driven by ICO on nuclear spins using the nu…
