Heisenberg-limited metrology with perturbing interactions
Chao Yin, Andrew Lucas
We show that it is possible to perform Heisenberg-limited metrology on GHZ-like states, in the presence of generic spatially local, possibly strong interactions during the measurem…
Polynomial-time classical sampling of high-temperature quantum Gibbs states
Chao Yin, Andrew Lucas
The computational complexity of simulating quantum many-body systems generally scales exponentially with the number of particles. This enormous computational cost prohibits first p…
Speed limits and locality in many-body quantum dynamics
Chi-Fang Chen, Andrew Lucas, Chao Yin
We review the mathematical speed limits on quantum information processing in many-body systems. After the proof of the Lieb-Robinson Theorem in 1972, the past two decades have seen…
Mixed-State Entanglement Measures in Topological Order
Chao Yin, Shang Liu
Quantum entanglement is a particularly useful characterization of topological orders which lack conventional order parameters. In this work, we study the entanglement in topologica…
