The study of non-equilibrium physics from the perspective of the quantum limits of thermodynamics and fluctuation relations can be experimentally addressed with linear optical systems. We discuss recent experimental investigations in this scenario and present new proposed schemes while discussing the potential advances they could bring to the field of quantum thermodynamics. 
Experimental study of the generalized Jarzynski fluctuation relation using entangled photons
Optical modes possessing orbital angular momentum constitute a very useful platform for experimental studies on the quantum limits of Thermodynamics. Here, we present experimental results for
Remote preparation of single photon vortex thermal states
Photon pairs produced in spontaneous parametric down-conversion are naturally entangled in their transverse spatial degrees of freedom including the orbital angular momentum. Pumping a non-linear
Gauge invariant quantum thermodynamics: consequences for the first law
Universality of classical thermodynamics rests on the central limit theorem, due to which, measurements of thermal fluctuations are unable to reveal detailed information regarding the microscopic
Thermodynamic length and work optimization for Gaussian quantum states
Constructing optimal thermodynamic processes in quantum systems relies on managing the balance between the average excess work and its stochastic fluctuations. Recently it has been shown that two
Joint measurability in non-equilibrium quantum thermodynamics
Quantum work and fluctuation theorems are mostly discussed in the framework of projective two-point measurement (TPM) schemes. According to a well known no-go theorem, there is no work observable
Second law of thermodynamics for batteries with vacuum state
TLDR
It is shown that the existence of battery ground state leads to a thermodynamic behaviour which cannot be realized using an ideal weight, and this remains true even when battery operates far from its bottom.
Measurement-based quantum heat engine in a multilevel system
We compare quantum Otto engines based on two different cycle models: a two-bath model, with a standard heat source and sink, and a measurement-based protocol, where the role of heat source is played
Noisy quantum metrology with the assistance of indefinite causal order
A generic qubit unitary operator affected by depolarizing noise is duplicated and inserted in a quantum switch process realizing a superposition of causal orders. The characterization of the

The Jarzynski equality, relating non-equilibrium processes to free-energy differences between equilibrium states, has been verified in a number of classical systems. An ion-trap experiment now
Quantum extension of the Jarzynski relation: analogy with stochastic dephasing.
TLDR
A close formal analogy is established between the present "classical trajectory" picture over populations of adiabatic states and phase fluctuations of a quantum coherence in spectral line shapes, described by the stochastic Liouville equation.
Experimental demonstration of information to energy conversion in a quantum system at the Landauer limit
TLDR
The scheme presented here allows for the detailed study of irreversible entropy production in quantum information processors and verification that an operation that changes the information content of the system must necessarily generate heat in the reservoir, exactly as predicted by Landauer’s principle.
Quantum Simulation of Single-Qubit Thermometry Using Linear Optics.
TLDR
Standard thermometry is illustrated by performing a simulation of the qubit-environment interaction in a linear-optical device and discussing the role of the coherence and how this affects the usefulness of nonequilibrium conditions.

TLDR
This work shows that the characteristic function of the work distribution for a nonequilibrium quench of a general quantum system can be extracted by Ramsey interferometry of a single probe qubit.

The characteristic function of the work performed by an external time-dependent force on a Hamiltonian quantum system is identified with the time-ordered correlation function of the exponentiated

Feedback mechanisms such as the ‘demon’ in Maxwell’s well-known thought experiment can, in principle, enable the transformation of information into energy, without violating the second law of

TLDR
The first lawlike balance between applied work, exchanged heat, and internal energy on the level of a single trajectory is demonstrated, and the observed distribution of applied work is distinctly non-Gaussian in good agreement with numerical calculations.
