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…
Symplectic geometry and circuit quantization
Andrew Osborne, Trevyn Larson, Sarah Jones +3
Circuit quantization is an extraordinarily successful theory that describes the behavior of quantum circuits with high precision. The most widely used approach of circuit quantizat…
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…
Locality and error correction in quantum dynamics with measurement
Aaron J. Friedman, Chao Yin, Yifan Hong +1
The speed of light sets a strict upper bound on the speed of information transfer in both classical and quantum systems. In nonrelativistic quantum systems, the Lieb-Robinson T…
Quantum error correction in a time-dependent transverse field Ising model
Yifan Hong, Jeremy T. Young, Adam M. Kaufman +1
We describe a simple quantum error correcting code built out of a time-dependent transverse field Ising model. The code is similar to a repetition code, but has two advantages: an…
