Physicists Showcase Innovative Technique for Generating Photons

Scientists at Leiden University have successfully demonstrated a new method for producing individual photons, which are crucial for quantum cryptography and quantum computers. In a publication in Physical Review Letters on July 23rd, the researchers explained how they created single photons using a laser and a quantum dot inside an optical cavity.

This new method, known as “photon blockade,” overcomes the challenge of residual laser light interfering with the production of single photons. The experimental evidence provided by the Leiden researchers supports this innovative approach, which could have significant implications for the field of quantum optics.Scientists at Leiden University have successfully demonstrated a new method for producing individual photons, which are crucial for quantum cryptography and quantum computers.
