Researchers have used an ensemble of NV− centers in diamond for implementing different types of quantum heat engines. They have used these to demonstrate the equivalence of the power output of two ...

In and out: An illustration of the quantum engine as a piston, showing the piston compressed when the particles in the gas exist as bosonic molecules and expanded when they are individual fermionic ...

Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem ...

(Nanowerk News) Researchers from Aalto University are designing nano-sized quantum heat engines to explore whether they may be able to outperform classical heat engines in terms of power and ...

(Nanowerk News) Classical motors convert a form of energy such as heat into mechanical work. Can these laws also be transferred to a miniature machine that consists of only a single cesium atom and ...

The theoretical notion of a 'quantum heat engine' has been around for several decades. It was first introduced around sixty years ago by Scovil and Schulz-DuBois, two physicists at Bell Labs who drew ...

Heat engines are devices that utilize waste heat to perform mechanical work and generate power. The invention of heat engines ushered in an era of the industrial revolution two hundred fifty years ago ...

Power boost: a quantum heat engine in synthetic diamond. (Courtesy: Jonas Becker) Physicists have in recent years built a number of microscopic heat engines to investigate how the laws of ...

Researchers in Singapore have built a refrigerator that's just three atoms big. This quantum fridge won't keep your drinks cold, but it's cool proof of physics operating at the smallest scales. The ...

Researchers are designing nano-sized quantum heat engines to explore whether they may be able to outperform classical heat engines in terms of power and efficiency. Researchers from Aalto University ...
