Operation Mpemba effect: Breakdown of resource-Markovianity of free dynamics

Tian-Ren Jin, Yu-Ran Zhang, Heng Fan

The Mpemba effect refers to faster relaxation of states that are initially farther from equilibrium, yet its characterization is often tied to a chosen distance or resource measure…

Capacity, Not Format: Rethinking Structured Reasoning Failures

Hengxin Fan

Prior work treats structured output as a reasoning tax, but this framing is incomplete: the cost of formatting depends strongly on a model's spare capacity. Using information-match…

Generalized Entanglement of Purification Criteria for 2-Producible States in Multipartite Systems

Tian-Ren Jin, Yu-Ran Zhang, Heng Fan

Multipartite entanglement has a much more complex structure than bipartite entanglement. A state that lacks generic multipartite entanglement is 2-producible, i.e. it can be writte…

Digital Quantum Simulation of the Lindblad Master Equation and Its Nonlinear Extensions via Quantum Trajectory Averaging

Yu-Guo Liu, Heng Fan, Shu Chen

Since precisely controlling dissipation in realistic environments is challenging, digital simulation of the Lindblad master equation (LME) is of great significance for understandin…

Markov Gap and Bound Entanglement in Haar Random State

Tian-Ren Jin, Shang Liu, Heng Fan

Bound entanglement refers to entangled states that cannot be distilled into maximally entangled states and therefore cannot directly be used in many quantum information processing…
