Summary: Maxwell's demon is a classic thought experiment that paradoxically violates the second law of thermodynamics. With advancements in nanomachinery, this experiment has become increasingly important in practical applications. Existing explanations fail to resolve this paradox, necessitating the proposal of a purely mechanical solution.

Summary: We study an autonomous model of a Maxwell demon that rectifies thermal fluctuations of chemical reactions. We analyze its scaling behavior, performances, and the impact of potential internal delays. Analytical expressions are obtained for all quantities of interest, including the reverse chemical current, output power, transduction efficiency, and correlation between the number of molecules. Due to a bound on the nonequilibrium response, the Maxwell demon is unable to generate a finite output in the macroscopic limit.

Summary: The interplay between thermal machines and quantum correlations is explored, with a focus on the fragility of quantum-fueled machines in the presence of decoherence effects. A second demon is introduced to address this issue, allowing the work medium to pass through two dephasing channels via quantum superposition. A quantum circuit is proposed and tested on IBMQ and IonQ quantum computers.

Summary: This study focuses on generating photon pairs with high degrees of polarization entanglement and high indistinguishability. It achieves this by selectively reducing the biexciton lifetime with an optical resonator. Through the optimization of photonic structures and microscopic simulations of quantum-dot cavity excitation dynamics, it determines the optimal range of Purcell enhancement for maximizing indistinguishability and entanglement.

Summary: This study focuses on refining the concept of Maxwell's demon to explore the limit of energy dissipation in open systems, uncovering a previously unexplored set of fluctuation theorems. These theorems reveal the existence of an intrinsic nonequilibrium state in the system, guided by nonnegative demon-induced dissipative information. The analysis suggests that the bounds of both work and heat in the system are tighter than previously predicted, and proposes a potential experimental test to verify these boundaries.

Summary: The paper discusses how obtaining information of a quantum system through quantum measurements can bring disturbances to the system and affect the entanglement between arbitrary bipartite systems. By modeling the measurement process as tripartite systems and defining various information quantities, the relationships between information gain and entanglement in the tripartite systems are explored.

Summary: This paper revisits the quantum Maxwell demon problem in a thermodynamic feedback cycle under steady-state conditions. A generalized version of the Clausius inequality for a finite-time steady feedback cycle with a single heat bath is derived, which is shown to be tighter than previously known versions. This allows us to clarify that feedback control is necessary to violate the standard Clausius inequality.

Summary: The study on Maxwell's demon problem revisits the issue from the perspectives of energy conservation, entropy increase principle, thermomass energy, and relativistic energy, providing insights on the impacts of information. The analysis shows that the negative entropy carried by information corresponds to positive thermomass energy, not the product of entropy and temperature. This demonstrates that the information energy plays a crucial role in promoting heat transfer in the system according to reversible energy conservation analyses, aligning with the second law of thermodynamics.

Summary: Researchers introduce a robust Maxwell demon that can generate many-body entanglement against bit-flip noises, leading to quantum advantage. They utilize the voter model protocol and derive upper bounds for entropy reduction and work extraction rates. These findings suggest that many-body entanglement stabilization and work extraction are possible under certain conditions.

Summary: Engineered dynamical maps have shown technological applications and potential in quantum thermodynamic processes. In this study, we experimentally realized an autonomous feedback process with tunable dissipative strength by controlling the nitrogen-vacancy center. The efficacy of the feedback process was quantified using a generalized Sagawa-Ueda-Tasaki relation for dissipative dynamics.

Summary: The second law of classical equilibrium thermodynamics states that any process occurs with the loss of information and irreversibility, however, in quantum processes fluctuations may lead to negative entropy production, where heat flows from a cold system to a hot system and information flows back into the system. This apparent violation of the Second Law can be resolved by explicitly incorporating information into the law and describing negative and positive entropy production with a quantum thermodynamic force.

Summary: Measurement plays a crucial role in controlling quantum systems. Weak measurements, through their back action on the system, can enable coherent control and induce topological transitions in geometric phases. This connection reveals subtle topological features in measurement-based manipulation of quantum systems and opens up new avenues for measurement-enabled quantum control of many-body topological states.

Summary: We analyze the generation and destruction of entanglement in a one-dimensional quantum spin chain under locally noisy and disordered Hamiltonian using the concept of a measurement-induced entanglement transition. By continuously measuring the system, we induce a transition from volume to area-law scaling of the steady-state entanglement entropy. The critical measurement strength is systematically reduced by static background disorder, but the dependence on the strength of nonstatic noise is nonmonotonic. According to the extracted finite-size scaling exponents, the universality class of the transition is independent of the noise and disorder strength.
