Theory of variational quantum simulation
Xiao Yuan, Suguru Endo, Qi Zhao +2
The variational method is a versatile tool for classical simulation of a variety of quantum systems. Great efforts have recently been devoted to its extension to quantum computing…
A high threshold code for modular hardware with asymmetric noise
Xiaosi Xu, Qi Zhao, Xiao Yuan +1
We consider an approach to fault tolerant quantum computing based on a simple error detecting code operating as the substrate for a conventional surface code. We develop a customis…
Testing Local Realism into the Past without Detection and Locality Loopholes
Ming-Han Li, Cheng Wu, Yanbao Zhang +16
Inspired by the recent remarkable progress in the experimental test of local realism, we report here such a test that achieves an efficiency greater than (78%)^2 for entangled phot…
Mitigating algorithmic errors in Hamiltonian simulation
Suguru Endo, Qi Zhao, Ying Li +2
Quantum computers can efficiently simulate many-body systems. As a widely used Hamiltonian simulation tool, the Trotter-Suzuki scheme splits the evolution into the number of Trotte…
One-Shot Coherence Distillation: Towards Completing the Picture
Qi Zhao, Yunchao Liu, Xiao Yuan +2
The resource framework of quantum coherence was introduced by Baumgratz, Cramer and Plenio [PRL 113, 140401 (2014)] and further developed by Winter and Yang [PRL 116, 120404 (2016)…
Device independent quantum random number generation
Yang Liu, Qi Zhao, Ming-Han Li +16
Randomness is critical for many information processing applications, including numerical modeling and cryptography. Device-independent quantum random number generation (DIQRNG) bas…
