A quantum Szilard engine that can achieve two-level system hyperpolarization
Quantum computers, machines that perform computations exploiting quantum mechanical phenomena, could eventually outperform classical computers on some tasks, by utilizing quantum mechanical resources such as state superpositions ...
Researchers 'split' phonons in step toward new type of quantum computer
When we listen to our favorite song, what sounds like a continuous wave of music is actually transmitted as tiny packets of quantum particles called phonons.
