Quantum devices: Towards entangled electrons

Zusammenfassung

A new method has been developed for extracting Cooper pairs from a superconductor and splitting them. The next challenge is to show that these unpaired electrons are entangled.

Quantum mechanics describes physical properties such as polarization or spin in terms of quantum states. Two particles are said to be entangled if the measurement or manipulation of the quantum state of one particle affects that of the other particle
