Learning Quantum Hamiltonians from Single-qubit Measurements
Liangyu Che, Chao Wei, Yulei Huang +6
It is natural to measure the observables from the Hamiltonian-based quantum dynamics, and its inverse process that Hamiltonians are estimated from the measured data also is a vital…
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…
Testing a Quantum Error-Correcting Code on Various Platforms
Qihao Guo, Yuan-Yuan Zhao, Markus Grassl +5
Quantum error correction plays an important role in fault-tolerant quantum information processing. It is usually difficult to experimentally realize quantum error correction, as it…
Quantum Pure State Tomography via Variational Hybrid Quantum-Classical Method
Tao Xin, Xinfang Nie, Xiangyu Kong +3
To obtain a complete description of a quantum system, one usually employs standard quantum state tomography, which however requires exponential number of measurements to perform an…
Experimental Detection of the Quantum Phases of a Three-Dimensional Topological Insulator on a Spin Quantum Simulator
Tao Xin, Yishan Li, Yu-ang Fan +6
The detection of topological phases of matter becomes a central issue in recent years. Conventionally, the realization of a specific topological phase in condensed matter physics r…
