Engines are systems and devices that convert one form of energy into another, typically into
a more useful form that can perform work. In the classical setup, physical, chemical, and …

The advantages of quantum effects in several technologies, such as computation and
communication, have already been well appreciated. Some devices, such as quantum …

Thermodynamics connects our knowledge of the world to our capability to manipulate and
thus to control it. This crucial role of control is exemplified by the third law of …

In the quantum regime, the third law of thermodynamics implies the unattainability of pure
states. As shown recently, such unattainability implies that a unitary interaction between the …

Practical implementations of quantum technologies require preparation of states with a high
degree of purity—or, in thermodynamic terms, very low temperatures. Given finite resources …

Miniaturization has been the driving force in contemporary technologies. However, two main
obstacles limit further progress: additional reduction in size has reached its quantum limit …

Energy consumption in solving computational problems has been gaining growing attention
as a part of the performance measures of computers. Quantum computation is known to offer …

The laws of thermodynamics are usually formulated under the assumption of infinitely large
environments. While this idealization facilitates theoretical treatments, real physical systems …

Quantum technologies and experiments often require preparing systems in low-temperature
states. Here, we investigate cooling schemes using feedback protocols modeled with a …

Within quantum thermodynamics, many tasks are modeled by processes that require work
sources represented by out-of-equilibrium quantum systems, often dubbed quantum …
