Characterizing Quantum Supremacy in Near-Term Devices
Sergio Boixo, Sergei V. Isakov, Vadim N. Smelyanskiy +6
A critical question for the field of quantum computing in the near future is whether quantum devices without error correction can perform a well-defined computational task beyond t…

Scaling analysis and instantons for thermally-assisted tunneling and Quantum Monte Carlo simulations
Zhang Jiang, Vadim N. Smelyanskiy, Sergei V. Isakov +4
We develop an instantonic calculus to derive an analytical expression for the thermally-assisted tunneling decay rate of a metastable state in a fully connected quantum spin model.…
