Observable Estimation in the Absence of Classical Verification
Samantha V. Barron, Bradley Mitchell, Vinay Tripathi +45
The paper proposes a framework to independently validate observable estimates from quantum computers when classical benchmarks are unavailable, using experiments such as the operat…
Relaxation Process During Complex Time Evolution In Two-Dimensional Integrable and Chaotic CFTs
Chen Bai, Weibo Mao, Masahiro Nozaki +2
We investigate the complex time evolution of a vacuum state with the insertion of a local primary operator in two-dimensional conformal field theories (2d CFTs). This complex time…
Almost Countable Spectrum and Logarithmic Sarnak Conjecture
Wen Huang, Maoru Tan, Leiye Xu
In this paper, we introduce topological dynamical systems with almost countable spectrum. We prove that the Logarithmic Sarnak Conjecture holds for zero-entropy topological dynamic…
Spatially Structured Entanglement from Nonequilibrium Thermal Pure States
Chen Bai, Mao Tian Tan, Bastien Lapierre +1
We study quantum quench dynamics in (1+1)-dimensional critical systems, starting from thermal pure states called crosscap states, and evolving them under spatially inhomogeneous Ha…
Non-Equilibrating a Black Hole with Inhomogeneous Quantum Quench
Kanato Goto, Masahiro Nozaki, Shinsei Ryu +2
We study quantum quench processes in (1+1)-dimensional conformal field theory (CFT) in which the initial thermal equilibrium (Gibbs) state is time-evolved by spatially inhomogeneou…
