Superconducting qubits can function as quantum engines

(Phys.org)—Physicists have shown that superconducting circuits—circuits that have zero electrical resistance—can function as piston-like mechanical quantum engines. The new perspective may help researchers design quantum ...

A quantum computer to tackle fundamental science problems

For more than 50 years, Moore's Law has reigned supreme. The observation that the number of transistors on a computer chip doubles roughly every two years has set the pace for our modern digital revolution—making smartphones, ...

Experimental method measures robustness of quantum coherence

Researchers at the UAB have come up with a method to measure the strength of the superposition coherence in any given quantum state. The method, published in the journal Proceedings of the Royal Society A, is based on the ...

Three-way battles in the quantum world

In phase transitions, for instance between water and water vapor, the motional energy competes with the attractive energy between neighboring molecules. Physicists at ETH Zurich have now studied quantum phase transitions ...
