Hayden--Preskill recovery at finite temperature on a quantum processor: dynamics and initial state from the SYK model
Jeongho Bang, Moongul Byun, Kyoungho Cho +2
The paper extends the Hayden‑Preskill information recovery protocol by linking the scrambler to the initial state with a SWAP gate and studying recovery at finite temperature, show…
Exact No Signaling in Time without Temporal Classicality
Minsu Kim, Jeongho Bang, Han Seb Moon
The paper demonstrates that exact no‑signaling‑in‑time (NSIT) does not guarantee a classical temporal description, by analytically solving common fixed points of nonselective measu…
Hidden Complex Structure in Quotient-Space Real Quantum Mechanics
Jeongho Bang, Kyoungho Cho, Kyunghyun Baek
Barrios Hita et al. [Phys. Rev. Lett. , 240202 (2026)] argued that quantum mechanics can be formulated over the real numbers by replacing the tensor-product postulate wit…
Breaking the One-Dimensional Expressibility-Trainability Tradeoff
Kyoungho Cho, Yu-Seong Jeon, Jinhyoung Lee +1
Expressive parameterized quantum circuits (PQCs) are often designed under a dilemma: the growth of expressibility and entangling power (EP) that improves Hilbert-space coverage is…
First-Quantized Relativistic Quantum Simulation with Periodic and Dirichlet Boundary Conditions
Jeongho Bang, Timothy P. Spiller, Kyunghyun Baek +2
In this work, we present a methodology for first-quantized relativistic quantum simulation on one-dimensional finite domains under the two boundary conditions most commonly used in…
No Reference-Free Generalization in Quantum Machine Learning
Jeongho Bang
Quantum machine learning is often motivated by the exponentially large state space of quantum systems, but this promise leaves a basic generalization problem unresolved: how can a…
