Quantum thermodynamics
Quantum thermodynamics is an emerging research field aiming to extend standard thermodynamics and non-equilibrium statistical physics to ensembles of sizes well below the thermodynamic limit, in
Computational power of correlations.
This work exposes an intriguing relationship between the violation of local realistic models and the computational power of entangled resource states in measurement-based quantum computation.
Quantum entanglement between the electron clouds of nucleic acids in DNA
We model the electron clouds of nucleic acids in DNA as a chain of coupled quantum harmonic oscillators with dipole-dipole interaction between nearest neighbours resulting in a van der Waals type
Ancilla-driven universal quantum computation
We introduce a model of quantum computation intermediate between the gate-based and measurement-based models. A quantum register is manipulated remotely with the help of a single ancilla that
Weak and Ultrastrong Coupling Limits of the Quantum Mean Force Gibbs State
The Gibbs state is widely taken to be the equilibrium state of a system in contact with an environment at temperature T . However, non-negligible interactions between system and environment can give
Nanoscale temperature measurements using non-equilibrium Brownian dynamics of a levitated nanosphere.
Einstein realized that the fluctuations of a Brownian particle can be used to ascertain the properties of its environment. A large number of experiments have since exploited the Brownian motion of
Coherence and measurement in quantum thermodynamics
Information processing tasks, the so-called projections, that can only be formulated within the framework of quantum mechanics are identified and it is shown that the physical realisation of such projections can come with a non-trivial thermodynamic work only for quantum states with coherences.
Thermodynamics of discrete quantum processes
We define thermodynamic configurations and identify two primitives of discrete quantum processes between configurations for which heat and work can be defined in a natural way. This allows us to
A Sufficient Set of Experimentally Implementable Thermal Operations for Small Systems
Recent work using tools from quantum information theory has shown that at the nanoscale where quantum effects become prevalent, there is not one thermodynamical second law but many. Derivations of
From single-shot towards general work extraction in a quantum thermodynamic framework
A key conclusion here is that the single shot work for case (a) is appropriate only when a \emph{resonance} of a particular energy is required, and choosing the free energy difference of the weight as the transfer-quantity one recovers various single shot results.
