Symmetry protected topological order at nonzero temperature
Sam Roberts, Beni Yoshida, Aleksander Kubica +1
We address the question of whether symmetry-protected topological (SPT) order can persist at nonzero temperature, with a focus on understanding the thermal stability of several mod…
Chaos and complexity by design
Daniel A. Roberts, Beni Yoshida
We study the relationship between quantum chaos and pseudorandomness by developing probes of unitary design. A natural probe of randomness is the "frame potential," which is minimi…
Preparing topologically ordered states by Hamiltonian interpolation
Xiaotong Ni, Fernando Pastawski, Beni Yoshida +1
We study the preparation of topologically ordered states by interpolating between an initial Hamiltonian with a unique product ground state and a Hamiltonian with a topologically d…
Topological Order and Memory Time in Marginally Self-Correcting Quantum Memory
Karthik Siva, Beni Yoshida
We examine two proposals for marginally self-correcting quantum memory, the cubic code by Haah and the welded code by Michnicki. In particular, we prove explicitly that they are ab…
