Quantum States Reveal Themselves with Measurable 'Fingerprint'

Caption

Measuring the fingerprint of quantum states could help to guard against errors and defective devices in quantum technologies. The existence of such a fingerprint was previously known only for limited cases: researchers in Singapore and the United States have now calculated how to measure a fingerprint for all states of two entangled particles. The findings were published May 26 in Nature Communications.
