Theory of Quantum Imaginary-Time Mpemba Effect
Yumeng Zeng, Jeongrak Son, Mile Gu +1
Quantum imaginary-time evolution (QITE) is a fundamental framework for preparing ground and thermal states, yet its computational cost scales significantly with the evolution durat…

Reinforcement learning for quantum processes with memory
Josep Lumbreras, Ruo Cheng Huang, Yanglin Hu +2
In reinforcement learning, an agent interacts sequentially with an environment to maximize a reward, receiving only partial, probabilistic feedback. This creates a fundamental expl…

Quantum limits of covert target detection
Guo Yao Tham, Ranjith Nair, Mile Gu
In covert target detection, Alice attempts to send optical or microwave probes to determine the presence or absence of a weakly-reflecting target embedded in thermal background rad…
