Symmetry-initialized quantum Gibbs sampling: a non-Abelian asymmetry cascade

Soo-Jong Rey

For a quantum Gibbs sampler whose mixing bottleneck is a weakly broken symmetry, I show that the correct initialization is determined by representation theory. I first prove a gene…

$p$ -Form Gauge Dynamics and Digital Quantum Simulation -- Flux and Cosmological Constant Neutralization

Soo-Jong Rey

I develop a Hamiltonian framework for $Z_{k}$ $p$ -form gauge fields on arbitrary oriented cell complexes in arbitrary dimensions. Gauge qudits are defined by $p$ -cells, cha…

Infrared Safety from ZX-Diagrams: A Categorical Proof of Soft-QED as Open Quantum System

Soo-Jong Rey

The discard ZX-calculus, a diagrammatic language for mixed-state quantum mechanics, is used to give a nonperturbative, categorical proof of the Bloch-Nordsieck cancellation of infr…
