Quantum Ping-Pong: The New Era of Atomic Photon Control
Posted by Saúl Morales Rodriguéz in categories: particle physics, quantum physics
Scientists have developed “quantum ping-pong”: Using a special lens, two atoms can be made to bounce a single photon back and forth with high precision.
Atoms can absorb and reemit light — this is an everyday phenomenon. In most cases, however, an atom emits a light particle in all possible directions — recapturing this photon is therefore quite hard.
