: Using "anti-bunching" to ensure a source emits exactly one photon at a time, critical for secure cryptography.

To study quantum effects, particles must be nearly still. Trapping techniques provide the controlled environment necessary for these observations. Quantum Optics Including Noise Reduction, Trapp...

: Squeezing "shirks" the uncertainty in one variable (like phase) by increasing it in another (like amplitude). : Using "anti-bunching" to ensure a source emits

: Combine magnetic fields and laser cooling to slow atoms to micro-Kelvin temperatures. : Squeezing "shirks" the uncertainty in one variable

The integration of noise reduction and trapping is leading to the . By trapping atoms (memory) and connecting them via low-noise squeezed light (transmission), we are building a network that is physically impossible to hack.

Classical optical measurements are limited by "shot noise," a result of the random arrival times of photons. Quantum optics overcomes this through .
