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…
Pulse-width-induced polarization enhancement of optically-pumped N-V electron spin in diamond
Yumeng Song, Yu Tian, Zhiyi Hu +7
The nitrogen-vacancy (N-V) center in diamond is a widely-used platform for quantum information processing and metrology. The electron-spin state of N-V center could be initialized…
Detecting scrambling via statistical correlations between randomized measurements on an NMR quantum simulator
Xinfang Nie, Ze Zhang, Xiuzhu Zhao +3
Out-of-time-order correlator (OTOC), been suggested as a measure of quantum information scrambling in quantum many-body systems, has received enormous attention recently. The exper…
Experimentally superposing two pure states with partial prior knowledge
Keren Li, Guofei Long, Hemant Katiyar +4
Superposition, arguably the most fundamental property of quantum mechanics, lies at the heart of quantum information science. However, how to create the superposition of any two un…
Experimental Estimation of Average Fidelity of a Clifford Gate on a 7-qubit Quantum Processor
Dawei Lu, Hang Li, Denis-Alexandre Trottier +8
Quantum gates in experiment are inherently prone to errors that need to be characterized before they can be corrected. Full characterization via quantum process tomography is impra…
