Fast quantum computation with all-to-all Hamiltonians
Chao Yin
All-to-all interactions arise naturally in many areas of theoretical physics and across diverse experimental quantum platforms, motivating a systematic study of their information-p…
Time Independence Does Not Limit Information Flow. I. The Free-Particle Case
Dong Yuan, Chao Yin, T. C. Mooney +3
The speed of information propagation in long-range interacting quantum systems is limited by Lieb-Robinson-type bounds, whose tightness can be established by finding specific quant…
Quantum Routing and Entanglement Dynamics Through Bottlenecks
Dhruv Devulapalli, Chao Yin, Andrew Y. Guo +4
To implement arbitrary quantum circuits in architectures with restricted interactions, one may effectively simulate all-to-all connectivity by routing quantum information. We consi…
Small correlation is sufficient for optimal noisy quantum metrology
Chao Yin, Victor V. Albert, Sisi Zhou
We propose a class of metrological resource states whose quantum Fisher information scales optimally in both system size and noise rate. In these states, qubits are partitioned int…
A polynomial-time classical algorithm for noisy quantum circuits
Thomas Schuster, Chao Yin, Xun Gao +1
We provide a polynomial-time classical algorithm for noisy quantum circuits. The algorithm computes the expectation value of any observable for any circuit, with a small average er…
