Role of Quantum Coherence in Thermodynamics [PDF]
PRX Quantum, 2022 We find necessary and sufficient conditions to determine the inter-convertibility of quantum systems under time-translation covariant evolution, and use it to solve several problems in quantum thermodynamics both in the single-shot and asymptotic regimes.

Finite-Time Quantum Landauer Principle and Quantum Coherence. [PDF]
Physical Review Letters, 2021 The Landauer principle states that any logically irreversible information processing must be accompanied by dissipation into the environment. In this Letter, we investigate the heat dissipation associated with finite-time information erasure and the ...

Experimental signature of initial quantum coherence on entropy production [PDF]
npj Quantum Information, 2022 We report on the experimental quantification of the contribution to non-equilibrium entropy production stemming from the quantum coherence content in the initial state of a qubit exposed to both coherent driving and dissipation.

Experimental Progress on Quantum Coherence: Detection, Quantification, and Manipulation [PDF]
Advanced Quantum Technologies, 2021 Quantum coherence is a fundamental property of quantum systems, separating quantum from classical physics. Recently, there has been significant interest in the characterization of quantum coherence as a resource, investigating how coherence can be ...

Relation between quantum coherence and quantum entanglement in quantum measurements [PDF]
Physical Review A, 2022 Quantum measurement is a class of quantum channels that sends quantum states to classical states. We set up resource theories of quantum coherence and quantum entanglement for quantum measurements and find relations between them.

Do photosynthetic complexes use quantum coherence to increase their efficiency? Probably not [PDF]
Science Advances, 2021 Quantum coherence probably does not enhance the efficiency of photosynthetic systems, but it may still play an important role. Answering the titular question has become a central motivation in the field of quantum biology, ever since the idea was raised ...

Accessible and inaccessible quantum coherence in relativistic quantum systems [PDF]
Physical Review A, 2021 The quantum coherence of a multipartite system is investigated when some of the parties are moving with uniform acceleration and the analysis is carried out using the single mode approximation.

Quantum coherence and distribution of N-partite bosonic fields in noninertial frame [PDF]
Classical and quantum gravity, 2021 We study the quantum coherence and its distribution of N-partite GHZ and W states of bosonic fields in the noninertial frames with arbitrary number of acceleration observers.

Entanglement, Coherence, and Extractable Work in Quantum Batteries. [PDF]
Physical Review Letters, 2022 We investigate the connection between quantum resources and extractable work in quantum batteries. We demonstrate that quantum coherence in the battery or the battery-charger entanglement is a necessary resource for generating nonzero extractable work ...

Photodiode-based time zero determination for ultrafast electron microscopy
Structural Dynamics, 2023 Pump-probe experiments in ultrafast electron microscopy require temporal overlap between the pump and probe pulses. Accurate measurements of the time delay between them allows for the determination of the time zero, the moment in time where both pulses ...
