Quantum-enhanced stochastic phase estimation with SU(1,1) interferometer
Kaimin Zheng, Minghao Mi, Ben Wang +5
The quantum stochastic phase estimation has many applications in the precise measurement of various physical parameters. Similar to the estimation of a constant phase, there is a s…
Quantum verification of NP problems with single photons and linear optics
Aonan Zhang, Hao Zhan, Junjie Liao +5
Quantum computing is seeking to realize hardware-optimized algorithms for application-related computational tasks. NP (nondeterministic-polynomial-time) is a complexity class conta…
Direct Characterization of Quantum Measurements using Weak Values
Liang Xu, Huichao Xu, Tao Jiang +5
The time-symmetric formalism endows the weak measurement and its outcome, the weak value,many unique features. In particular, it allows a direct tomography of quantum states withou…
Distillation of Gaussian Einstein-Podolsky-Rosen steering with noiseless linear amplification
Yang Liu, Kaimin Zheng, Haijun Kang +5
Einstein-Podolsky-Rosen (EPR) steering is one of the most intriguing features of quantum mechanics and an important resource for quantum communication. For practical applications,…
