Quantum Coherence and Ergotropy. [PDF]
Physical Review Letters, 2020 Constraints on work extraction are fundamental to our operational understanding of the thermodynamics of both classical and quantum systems. In the quantum setting, finite-time control operations typically generate coherence in the instantaneous energy ...

Quantum coherence resonance [PDF]
New Journal of Physics, 2020 It is shown that coherence resonance, a phenomenon in which regularity of noise-induced oscillations in nonlinear excitable systems is maximized at a certain optimal noise intensity, can be observed in quantum dissipative systems.

Quantum privacy and quantum coherence [PDF]
Physical Review Letters, 1997 We derive a simple relation between a quantum channel's capacity to convey coherent (quantum) information and its usefulness for quantum cryptography.Comment: 6 pages RevTex; two short comments added 7 October ...

Quantum Computers and Quantum Coherence [PDF]
Journal of Magnetism and Magnetic Materials, 1999 If the states of spins in solids can be created, manipulated, and measured at the single-quantum level, an entirely new form of information processing, quantum computing, will be possible.

Converting Coherence to Quantum Correlations [PDF]
Physical Review Letters, 2016 Recent results in quantum information theory characterize quantum coherence in the context of resource theories. Here we study the relation between quantum coherence and quantum discord, a kind of quantum correlation which appears even in non-entangled states.

Set Coherence: Basis-Independent Quantification of Quantum Coherence. [PDF]
Physical Review Letters, 2020 The coherence of an individual quantum state can be meaningfully discussed only when referring to a preferred basis. This arbitrariness can, however, be lifted when considering sets of quantum states.

Quantum coherence in a quantum heat engine [PDF]
Journal of Physics A: Mathematical and Theoretical, 2019 We identify that quantum coherence is a valuable resource in the quantum heat engine, which is designed in a quantum thermodynamic cycle assisted by a quantum Maxwell’s demon. This demon is in a superposed state.

Probabilistic Distillation of Quantum Coherence. [PDF]
Physical Review Letters, 2018 The ability to distill quantum coherence is pivotal for optimizing the performance of quantum technologies; however, such a task cannot always be accomplished with certainty.

Quantum coherence via skew information and its polygamy [PDF]
Physical Review A, 2017 Quantifying coherence is a key task in both quantum mechanical theory and practical applications. Here, a reliable quantum coherence measure is presented by utilizing the quantum skew information of the state of interest subject to a certain broken ...

Quantum-coherent nanoscience [PDF]
Nature Nanotechnology, 2021 For the past three decades, nanoscience has widely affected many areas in physics, chemistry, and engineering, and has led to numerous fundamental discoveries as well as applications and products. Concurrently, quantum science and technology has developed into a cross-disciplinary research endeavour connecting these same areas and holds a burgeoning ...
