Quantum entanglement has shifted from a philosophical puzzle to a design brief for engineers working at the scale of atoms, photons and phonons. As researchers learn to control this fragile ...

Physicists developed simplified formulas to quantify quantum entanglement in strongly correlated electron systems. Their approach was applied to nanoscale materials, revealing unexpected quantum ...

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum ...
