Exact results about the nonequilibrium thermodynamics of open quantum systems at arbitrary timescales are obtained by considering all possible variations of initial conditions of a system. First we obtain a quantum-information theoretic equality for entropy production, valid for an arbitrary initial joint state of system and environment. For any finite-time process with a fixed initial environment, we then show that the system's loss of distinction-relative to the minimally dissipative state…

Impossibility of achieving Landauer's bound for almost every quantum state

The thermodynamic cost of resetting an arbitrary initial state to a particular desired state is lower bounded by Landauer’s bound. However, here we demonstrate that this lower bound is necessarily

Quantum Coherence and Ergotropy.

This work identifies a coherent contribution to the ergotropy (the maximum amount of unitarily extractable work via cyclical variation of Hamiltonian parameters) and shows this by dividing the optimal transformation into an incoherent operation and a coherence extraction cycle.

Quantum Work Statistics with Initial Coherence

A quantitative comparison between both schemes is established in terms of the amount of coherence present in the initial state of the system, as quantified by the l1-coherence measure, and it is proved that the average entropy production can take negative values in the Margenau–Hill framework.

The state dependence of integrated, instantaneous, and fluctuating entropy production in quantum and classical processes

This work derives novel bounds on EP, analyzes the thermodynamics of quantum error correction, and proposes a thermodynamically-motivated measure of the logical irreversibility of a channel.

Thermodynamic machine learning through maximum work production

It is demonstrated that an efficient agent’s model explicitly determines its architecture and how much useful work it harvests from the environment, and establishes an equivalence between nonequilibrium thermodynamics and dynamic learning.

Fundamental energy cost of finite-time parallelizable computing

It is shown that the energy cost per operation of a parallel computer can be kept very small, even for large problem sizes, whereas that of a serial computer fundamentally diverges.

Generalized Zurek's bound on the cost of an individual classical or quantum computation

Stochastic thermodynamics is used to derive a generalized version of Zurek's bound from a rigorous Hamiltonian formulation, which applies to all quantum and classical processes, whether noisy or deterministic, and it explicitly captures the dependence on the protocol.

First and Second Laws of Information Processing by Nonequilibrium Dynamical States

The averaged steady-state surprisal links a driven stochastic system’s information processing to its nonequilibrium thermodynamic response. By explicitly accounting for the effects of nonequilibrium

Nonequilibrium thermodynamics of uncertain stochastic processes

Stochastic thermodynamics is formulated under the assumption of perfect knowledge of all thermodynamic parameters. However, in any real-world experiment there is non-zero uncertainty about the

Engines for predictive work extraction from memoryful quantum stochastic processes

A phase transition in the efficacy of knowledge for work extraction from quantum processes, which is without classical precedent is discovered, which opens up the prospect of machines that harness environmental free energy in an essentially quantum, essentially time-varying form.



Thermodynamic length in open quantum systems

The dissipation generated during a quasistatic thermodynamic process can be characterised by introducing a metric on the space of Gibbs states, in such a way that minimally-dissipating protocols

Role of coherence in the nonequilibrium thermodynamics of quantum systems.

It is proved that a division of the irreversible work can be made into a coherent and incoherent part, which provides an operational criterion for quantifying the coherent contribution in a generic nonequilibrium transformation on a closed quantum system.

Fully quantum fluctuation theorems

Systems that are driven out of thermal equilibrium typically dissipate random quantities of energy on microscopic scales. Crooks fluctuation theorem relates the distribution of these random work

The role of quantum coherence in non-equilibrium entropy production

Thermodynamic irreversibility is well characterized by the entropy production arising from non-equilibrium quantum processes. We show that the entropy production of a quantum system undergoing

Landauer's principle in the quantum regime.

We demonstrate the validity of Landauer's erasure principle in the strong coupling quantum regime by treating the system-reservoir interaction in a thermodynamic way. We show that the initial

Quantifying Memory Capacity as a Quantum Thermodynamic Resource.

A formalism is devised to quantify the thermodynamic value of memory in general quantum systems with nontrivial energy landscapes and outlines an explicit memory-bath coupling that can approximate the optimal qubit thermal information capacity arbitrarily well.

Reversing the direction of heat flow using quantum correlations

It is experimentally demonstrated the reversal of heat flow for two quantum correlated spins-1/2, initially prepared in local thermal states at different effective temperatures, employing a Nuclear Magnetic Resonance setup to observe a spontaneous energy flow from the cold to the hot system.

Resource theory of quantum states out of thermal equilibrium.

It is shown that the free energy of thermodynamics emerges naturally from the resource theory of energy-preserving transformations, provided that a sublinear amount of coherent superposition over energy levels is available, a situation analogous to the sub linear amount of classical communication required for entanglement dilution.

Steady-State Coherences by Composite System-Bath Interactions.

It is found that SSC become increasingly significant as the bath is cooled down, and this phenomenon is characterized analytically in the weak coupling regime for two paradigmatic models, and then numerically in more complex systems without any assumption on the coupling strength.

Fluctuation Theorems for a Quantum Channel

We establish the general framework of quantum fluctuation theorems by finding the symmetry between the forward and backward transitions of any given quantum channel. The Petz recovery map is adopted
