Logic gates are the elementary building blocks of computers. The finding that a single logic gate may drive a refrigerator is a beautiful demonstration that information-processing devices can have useful thermodynamic properties.

Quantum self-contained refrigerator in terms of the cavity quantum electrodynamics in the weak internal-coupling regime.
TLDR
Two schemes to implement the self-contained refrigerator in the framework of the cavity quantum electrodynamics indicate that the system with the weak internal coupling in the infinite dimensional Hilbert space can be used to realize the quantum self- contained refrigerator on the principle completely the same as the original self-containing refrigerator.
A pr 2 01 4 Experimental Heat-Bath Cooling of Spins
Algorithmic cooling (AC) is a method to purify quantum systems, such as ensembles of nuclear spins, or cold atoms in an optical lattice. When applied to spins, AC produces ensembles of highly…
Prospects and limitations of algorithmic cooling
TLDR
The limitations and prospects of heat-bath algorithmic cooling of spins are investigated, and lower bounds on the number of required reset steps are made use, based on entropy considerations, to present important consequences of using AC as a tool for improving signal-to-noise ratio in liquid-state magnetic resonance spectroscopy.

The smallest refrigerators can reach maximal efficiency
We investigate whether size imposes a fundamental constraint on the efficiency of small thermal machines. We analyse in detail a model of a small self-contained refrigerator consisting of three…
Realization of the quantum Toffoli gate with trapped ions.
TLDR
This work presents the first experimental realization of the quantum Toffoli gate in an ion trap quantum computer, achieving a mean gate fidelity of 71(3)%.
The thermodynamic meaning of negative entropy
TLDR
The main result is that the work cost of erasure is determined by the entropy of the system, conditioned on the quantum information an observer has about it, which gives a direct thermodynamic significance to conditional entropies, originally introduced in information theory.
The thermodynamics of computation—a review
Computers may be thought of as engines for transforming free energy into waste heat and mathematical work. Existing electronic computers dissipate energy vastly in excess of the mean thermal…
Implementation of a Toffoli gate with superconducting circuits
TLDR
By exploiting the third energy level of the transmon qubits, the number of elementary gates needed for the implementation of the Toffoli gate is significantly reduced, relative to that required in theoretical proposals using only two-level systems.
EXPERIMENTAL QUANTUM ERROR CORRECTION
Quantum error correction is required to compensate for the fragility of the state of a quantum computer. We report the first experimental implementations of quantum error correction and confirm the…
Algorithmic cooling and scalable NMR quantum computers
TLDR
Algorithmic cooling (via polarization heat bath)—a powerful method for obtaining a large number of highly polarized spins in liquid nuclear-spin systems at finite temperature, and the “spin-refrigerating” method suggests that this problem can be resolved.
Simplifying quantum logic using higher-dimensional Hilbert spaces
Quantum computation promises to solve fundamental, yet otherwise intractable, problems across a range of active fields of research. Recently, universal quantum logic-gate sets—the elemental building…
