Stopping Light: Physicists Move Quantum Computers Closer to Reality

Hmmm; like the graphic reminds of one of my posts.

In Brief.

  • Quantum computers would run some 100 million times faster than your PC, but they have proven to be a monumental feat of engineering.
  • In a new experiment, physicists managed to stop light, which helps us overcome challenges and brings us close to optical quantum computing.

A team of researchers at The Australian National University (ANU) may have found another work-around to bring us closer to quantum computing: The physicists have managed to find a new way to stop light.

Light was trapped by shining infrared lasers into ultra-cold atomic vapor. While the atoms absorbed some photons, a large amount were left in a frozen state in the atomic cloud — enhancing photon interaction with atoms or other photons.
