A design for a quantum engine that uses two entangled quantum bits and is powered by measuring their properties has been tested in the lab for the first time.
At the quantum scale, measuring an object’s property can change its energy. In 2021, Léa Bresque at Grenoble Alpes University in France and her colleagues developed a design for an engine that could be powered using only this energy change. Now, Bresque and other colleagues have tested this design in the lab.
The engine consists of two quantum bits or qubits…
