Title: Quantum Spin Squeezing Gets Real
Summary:
Researchers at NIST and JILA have demonstrated a new technique called “spin squeezing” that could significantly improve the accuracy of atomic clocks. The technique involves entangling atoms to reduce quantum noise, which currently limits the precision of atomic clocks.
Key Points:
– Spin squeezing creates entanglement between atoms, reducing quantum noise
– The technique could improve atomic clock accuracy by a factor of 10
– Applications include GPS, navigation, and measurements of gravitational waves
– The method has potential for other quantum sensors like rotation sensors and accelerometers
Status: Proof-of-concept demonstrated, further development needed for practical applications.
