Universal device for two-qubit entangled measurements via photonic quantum walks
Wen-Zhe Yan, Zhibo Hou, Jun-Feng Tang +4
Sophisticated quantum measurements are fundamental to obtain a quantum advantage in many informational problems. Here, we consider the task of guessing a direction encoded in a two…
Efficient Experimental Verification of Quantum Gates with Local Operations
Rui-Qi Zhang, Zhibo Hou, Jun-Feng Tang +5
Verifying the correct functioning of quantum gates is a crucial step towards reliable quantum information processing, but it becomes an overwhelming challenge as the system size gr…
Minimizing back-action through entangled measurements
Kang-Da Wu, Elisa Bäumer, Jun-Feng Tang +5
When an observable is measured on an evolving coherent quantum system twice, the first measurement generally alters the statistics of the second one, which is known as measurement…
Experimental optimal orienteering via parallel and antiparallel spins
Jun-Feng Tang, Zhibo Hou, Jiangwei Shang +4
Antiparallel spins are superior in orienteering to parallel spins. This intriguing phenomenon is tied to entanglement associated with quantum measurements rather than quantum state…
Direct estimation of quantum coherence by collective measurements
Yuan Yuan, Zhibo Hou, Jun-Feng Tang +4
The recently established resource theory of quantum coherence allows for a quantitative understanding of the superposition principle, with applications reaching from quantum comput…
Experimental realization of self-guided quantum process tomography
Zhibo Hou, Jun-Feng Tang, Christopher Ferrie +3
Characterization of quantum processes is a preliminary step necessary in the development of quantum technology. The conventional method uses standard quantum process tomography, wh…
Realization of a quantum autoencoder for lossless compression of quantum data
Chang-Jiang Huang, Hailan Ma, Qi Yin +6
As a ubiquitous aspect of modern information technology, data compression has a wide range of applications. Therefore, a quantum autoencoder which can compress quantum information…
Control-enhanced sequential scheme for general quantum parameter estimation at the Heisenberg limit
Zhibo Hou, Rui-Jia Wang, Jun-Feng Tang +4
The advantage of quantum metrology has been experimentally demonstrated for phase estimations where the dynamics are commuting. General noncommuting dynamics, however, can have dis…
Direct Measurement of the Two-dimensional Spatial Quantum Wavefunction via Strong Measurements
Chen-Rui Zhang, Meng-Jun Hu, Zhi-Bo Hou +6
Wavefunction is the foundation of quantum theory, which is assumed to give a complete description of a quantum system. For a long time, wavefunction is introduced as an abstract el…
Deterministic realization of collective measurements via photonic quantum walks
Zhibo Hou, Jun-Feng Tang, Jiangwei Shang +7
Collective measurements on identically prepared quantum systems can extract more information than local measurements, thereby enhancing information-processing efficiency. Although…
