Rigorous error bounds for dissipative thermal state preparation from weak system-bath coupling
Christopher Ong, S. A. Parameswaran, Benedikt Placke +1
Thermal state preparation is a central challenge in the simulation of quantum many-body systems. Yet, provably efficient algorithms for this task were only introduced recently [Che…
Optimal Decoding with the Worm
Zac Tobias, Nikolas P. Breuckmann, Benedikt Placke
We propose a new decoder for "matchable'' qLDPC codes that uses a Markov Chain Monte Carlo algorithm - called the worm algorithm - to approximately compute the probabilities of log…
Slow mixing and emergent one-form symmetries in three-dimensional gauge theory
Charles Stahl, Benedikt Placke, Vedika Khemani +1
Symmetry-breaking order at low temperatures is often accompanied by slow relaxation dynamics, due to diverging free-energy barriers arising from interfaces between different ordere…
