Local Determinacy of Quantum Master Equations and a Mechanical Interpretation of the Multi-Mode Jaynes-Cummings and Central Spin Models

Jaeha Lee, Miku Ishizaki

We propose a novel formulation of master equations for open systems wherein the evolution of a state is determined solely by its local behaviour at any point of time. Specifically,…

Exploring the holographic entropy cone via reinforcement learning

Temple He, Jaeha Lee, Hirosi Ooguri

We develop a reinforcement learning algorithm to study the holographic entropy cone. Given a target entropy vector, our algorithm searches for a graph realization whose min-cut ent…

Beyond Robertson-Schrödinger: A General Uncertainty Relation Unveiling Hidden Noncommutative Trade-offs

Gen Kimura, Aina Mayumi, Hiromichi Ohno +2

We report a universal improvement to the standard Robertson--Schrödinger uncertainty relation. Our result shows that the Robertson--Schrödinger lower bound can be supplemented by a…

A Necessary and Sufficient Condition for Quantum Realizability of Correlations for Arbitrary Normalized Observables in the Clauser--Horne--Shimony--Holt Setup

Ryosuke Nogami, Jaeha Lee

We establish a necessary and sufficient condition for the existence of a quantum state that reproduces given correlation values in the Clauser--Horne--Shimony--Holt (CHSH) setup fo…

Advantages of the Kirkwood-Dirac distribution among general quasi-probabilities for finite-state quantum systems

Shun Umekawa, Jaeha Lee, Naomichi Hatano

We investigate features of the quasi-joint-probability distribution for finite-state quantum systems, especially the two-state and three-state quantum systems, comparing different…
