Discovery of Optimal Quantum Error Correcting Codes via Reinforcement Learning

no code implementations10 May 2023 Vincent Paul Su, ChunJun Cao, Hong-Ye Hu, Yariv Yanay, Charles Tahan, Brian Swingle

Lastly, we comment on how this RL framework can be used in conjunction with physical quantum devices to tailor a code without explicit characterization of the noise model.

Quantum Gravity in the Lab: Teleportation by Size and Traversable Wormholes, Part II

no code implementations1 Feb 2021 Sepehr Nezami, Henry W. Lin, Adam R. Brown, Hrant Gharibyan, Stefan Leichenauer, Grant Salton, Leonard Susskind, Brian Swingle, Michael Walter

In [1] we discussed how quantum gravity may be simulated using quantum devices and gave a specific proposal -- teleportation by size and the phenomenon of size-winding.

Complexity growth of operators in the SYK model and in JT gravity

no code implementations27 Aug 2020 Shao-Kai Jian, Brian Swingle, Zhuo-Yu Xian

The concepts of operator size and computational complexity play important roles in the study of quantum chaos and holographic duality because they help characterize the structure of time-evolving Heisenberg operators.

Product Spectrum Ansatz and the Simplicity of Thermal States

1 code implementation3 Dec 2018 John Martyn, Brian Swingle

To address this problem, we propose a variational scheme to prepare approximate thermal states on a quantum computer by applying a series of two-qubit gates to a product mixed state.
