It is known that temperature estimates of macroscopic systems in equilibrium are most precise when their energy fluctuations are large. However, for nanoscale systems deviations from standard thermodynamics arise due to their interactions with the environment. Here we include such interactions and, using quantum estimation theory, derive a generalised thermodynamic uncertainty relation valid for classical and quantum systems at all coupling strengths. We show that the non-commutativity between… 

Temperature uncertainty relation in non-equilibrium thermodynamics

Temperature uncertainty of a quantum system in canonical ensemble is inversely determined by its energy fluctuation, which is known as the temperature-energy uncertainty relation. No such uncertainty

Temperature: The ignored factor in quantum mechanics.

We have developed a theoretical formalism to introduce temperature as a parameter into the framework of non-relativistic quantum mechanics using the laws of classical thermodynamics and the canonical

Nonperturbative renormalization of quantum thermodynamics from weak to strong couplings

By solving the exact master equation of open quantum systems, we formulate the quantum thermodynamics from weak to strong couplings. The open quantum systems exchange matters, energies and

Entropy production and fluctuation theorems in a continuously monitored optical cavity at zero temperature

Fluctuation theorems allow one to make generalised statements about the behaviour of thermodynamic quantities in systems that are driven far from thermal equilibrium. In this article we use Crooks'

Quantum Thermometry.

We discuss the application of techniques of quantum estimation theory and quantum metrology to thermometry. The ultimate limit to the precision at which the temperature of a system at thermal

Quantum-classical correspondence in spin-boson equilibrium states at arbitrary coupling

It is known that the equilibrium properties of nanoscale systems can deviate significantly from standard thermodynamics due to their coupling to an environment. For the generalised θ -angled

Entropy Production at Zero Temperature

Fluctuation theorems allow one to make generalised statements about the behaviour of thermodynamic quantities in systems that are driven far from thermal equilibrium. In this article we use Crooks’

Hamiltonian of Mean Force for Strongly-Coupled Systems

A central assumption in macroscopic thermodynamics is the weak coupling approximation, which posits that the equilibrium properties of a system are not influenced by the interactions with its

The problem of time is a notable obstacle towards the recognition of quantum theory as the ultimate fundamental description of nature. Quantum theory may not be complete if founded upon classical

Quantum work statistics close to equilibrium

We study the statistics of work, dissipation, and entropy production of a quantum quasi-isothermal process, where the system remains close to the thermal equilibrium along the transformation. We



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.

Thermodynamic Uncertainty Relations

Bohr and Heisenberg suggested that the thermodynamical quantities of temperature and energy are complementary in the same way as position and momentum in quantum mechanics. Roughly speaking their

Enhancement of low-temperature thermometry by strong coupling

We consider the problem of estimating the temperature T of a very cold equilibrium sample. The temperature estimates are drawn from measurements performed on a quantum Brownian probe strongly coupled

Global and local thermometry schemes in coupled quantum systems

We study the ultimate bounds on the estimation of temperature for an interacting quantum system. We consider two coupled bosonic modes that are assumed to be thermal and using quantum estimation

Operational approach to fluctuations of thermodynamic variables in finite quantum systems.

A quantum approach to the old problem of temperature fluctuations by observing that according to quantum thermodynamics, fluctuations of intensive parameters like temperature cannot exist and that such parameters are not observables, so their estimation has to be done indirectly.

Finite quantum dissipation: the challenge of obtaining specific heat

We consider a free particle coupled with finite strength to a bath and investigate the evaluation of its specific heat. A harmonic oscillator bath of Drude type with cutoff frequency ωD is employed

Precision measurements of temperature and chemical potential of quantum gases

We investigate the sensitivity with which the temperature and the chemical potential characterizing quantum gases can be measured. We calculate the corresponding quantum Fisher information matrices

Thermal energies of classical and quantum damped oscillators coupled to reservoirs

We consider the global thermal state of classical and quantum harmonic oscillators that interact with a reservoir. Ohmic damping of the oscillator can be exactly treated with a 1D scalar field

Entropy production and time asymmetry in the presence of strong interactions.

It is shown that the average entropy production quantifies the extent to which the system and bath state is driven away from the conditional equilibrium distribution and that the stochastic entropy production satisfies a generalized Crooks relation and can be used to quantify time asymmetry of correlated nonequilibrium processes.

Local quantum thermal susceptibility

This work introduces the local quantum thermal susceptibility, a quantifier for the best achievable accuracy for temperature estimation via local measurements, providing an operative strategy to address the local thermal response of arbitrary quantum systems at equilibrium.
