Getting the light to stop, an important step to making quantum computers
Recently, Australian scientists have succeeded in controlling light to help people get closer to making quantum computers and devices from the future.
Recently, Australian scientists have succeeded in controlling light to help people get closer to making quantum computers and devices from the future .
The team created a "trap" by projecting infrared lasers into an extremely cold stream of atoms causing light to be "retained" and photons moving around this "light trap".
Researcher Jesse Everett from Australian National University (ANU) said: "Cold atoms absorb some photons and the rest are frozen in supercooled clouds."
Photon moves at the speed of light (300,000 km / sec) without interacting with each other. In contrast, atoms often interact. Pause a group of photons in the cloud of super cold atoms to increase interaction.
This process will be used to build a quantum computer in the future.
Quantum computers are a computing device that directly uses the effects of quantum mechanics such as quantum superposition and entanglement to perform operations on input. Quantum computers have hardware different from transistor computers based on transistors.
Currently, Google owns a "given" quantum computer called D-Wave , which takes only 1 second to solve problems that computers typically take 10,000 years.
