Direct Fidelity Estimation of Quantum States using Machine Learning
Xiaoqian Zhang, Maolin Luo, Zhaodi Wen +4
In almost all quantum applications, one of the key steps is to verify that the fidelity of the prepared quantum state meets expectations. In this Letter, we propose a new approach…
Experimentally undoing an unknown single-qubit unitary
Qin Feng, Tianfeng Feng, Yuling Tian +2
Undoing a unitary operation, . reversing its action, is the task of canceling the effects of a unitary evolution on a quantum system, and it may be easily achieved when the un…
On-Chip Multiphoton Entangled States by Path Identity
Tianfeng Feng, Xiaoqian Zhang, Yuling Tian +1
Multiphoton entanglement, as a quantum resource, plays an essential role in linear optical quantum information processing. Krenn et al. (Phys. Rev. Lett. 118, 080401 2017) proposed…
A Steering Paradox for Einstein-Podolsky-Rosen Argument and its Extended Inequality
Tianfeng Feng, Changliang Ren, Qin Feng +4
The Einstein-Podolsky-Rosen (EPR) paradox is one of the milestones in quantum foundations, arising from the lack of local realistic description of quantum mechanics. The EPR parado…
