Giant Aoms’ title for recording time at room temperature

Giants atoms have an enthusiasm as contenders for making the best Real simulators and computers, as researchers prevented them for an immature time for an experiment at room temperature.

Remove an atom, sustain electromagnetic properties or laser lights – which changes the energy of its electrons – and you can use it to encode information. Do it with thousands of atoms and you have a computer in the quotum or a simulator for exotic amounts of value. However, after a time, atoms can change their state, indicating the errors. They are only controlled, and therefore useful, in a last “life”, which once was a maximum of 1400 seconds for room temperature experiments. Scientists have made traps of atoms longer, but those ways require the full setup placed in a giant fridge, Posing logistics challenges.

Zhenpu Zhang and Cindy Regal At the University of Colorado Boulder and their colleagues now break the record at room temperature. They used Atoms in Rydbergwhich is larger in diameter because some of their electrons are not far from their nuclear. The team loads the atoms in a vessel that is worthless to all air particles that disturb them, then grabbed each atom with lasers or “Optical Tweezers“It is a fundamental way of preventing atoms in Rydberg, which is more sensitive to electromagnetic fields and light.

Researchers also added a copper layer on the sides of the room, then cooled cooled to -269 ° C (-452 ° F). It protects atoms from heat, which can change their states. In addition, Zhang said any air particles deviated to the brass stick, similar to how warm water drops on a cold face. As a result, the team can continue atoms trapped and controlled for about 50 minutes – 3000 seconds, or almost twice as similar to previous experiments.

Zhang started building this setup about five years ago from near-scratch, as regal. “It’s like a total change how to think about doing these experiments,” he said.

Clément sayrin In Kantler Brossel Laboratory in France says the new method can be possible maneuvering many atomswhich can increase the power of computation to any computer or simulator made from them. “Three thousand seconds too long. You have to work to have these long-term life for atoms,” he said. However, having many atoms in the chamber also meant to use many lasers to control them, which may reduce the atoms of atoms, more Engineering challenges remainIt’s like.
