We show that a quantum Szilard engine containing many bosons with attractive interactions
enhances the conversion between information and work. Using an ab initio approach to the …

We review the basic properties of the quantum relative entropy for finite-dimensional Hilbert
spaces. In particular, we focus on several inequalities that are related to the second law of …

We study the reversible quantum Stirling cycle with a single spin or two coupled spins as the
working substance. With the single spin as the working substance, we find that under certain …

We construct a special four-level entangled quantum Otto heat engine based on the two-
qubit Heisenberg XX model, in which we assume that all the energy gaps are changed in …

We review theory of information thermodynamics, which incorporates effects of
measurement and feedback into nonequilibrium thermodynamics of a small system, and …

We generalize the quantum heat engine (QHE) model which was first proposed by Bender
et al.[J. Phys. A 33, 4427 (2000) 10.1088/0305-4470/33/24/302] to the case in which an …

The quantum Szilard engine (QSZE) is a conceptual quantum engine for understanding the
fundamental physics of quantum thermodynamics and information physics. We generalize …

Based on quantum thermodynamic processes, we make a quantum-mechanical (QM)
extension of the typical heat engine cycles, such as the Carnot, Brayton, Otto, Diesel cycles …

The semi-source independent quantum walk random number generator (SI-QW-QRNG) is a
cryptographic protocol that extracts a string of true random bits from a quantum random walk …

We have found the optimal conditions for work performed by the quantum Szilard engine
(SZE) containing multi-particles under isothermal processes with inevitable irreversibility …
