Google’s quantum computer manages to create a time crystal!

You are probably wondering what a time crystal is. Described as a new phase of matter out of equilibrium, it is a crystal that remains stable and ordered while constantly evolving and without emitting an ounce of energy.

Physicist Frank Wilczek first spoke about this periodic crystal structure in 2012. However, a number of physicists doubted the existence of such a material that could upset the traditional laws of thermodynamics. But researchers from Google, Stanford, Princeton and other universities wanted to prove its existence. To do this, they used Google’s quantum computer, Sycamore.

How did they use Google’s quantum computer?

They claim in a recent study that they used Google’s quantum computer to build a time crystal. The researchers explained in their preprints that they used ” a time inversion protocol that discriminates the external decoherence of intrinsic thermalization and takes advantage of quantum typicality to bypass the exponential cost of dense sampling of the eigen spectrum “.

In addition, the researchers have located the phase transition ” out of the DTC with an experimental analysis of finite size. These results establish an evolutionary approach to study non-equilibrium phases of matter on current quantum processors. », Reports Trust My Science.

The composition of the time crystal

For information, the time crystal is made up of three basic elements: a row of particles that each have a particular magnetic orientation that is enclosed in a mixture of low and high energy configurations, which are called ” multi-body localization “. The second element is the reversal of orientations of these particles which is called “order of proper state”. This is a localized condition secondary to several bodies. And finally, laser light which causes a cycle of states without actually using the net energy of the laser itself. The result is known as ” Floquet time crystal “. The researchers concluded that this research provides ” evolutionary approach to study non-equilibrium phases of matter on current quantum processors “.

Ultimately, one might believe that temporal crystals could bring about a real revolution. However, in truth, researchers have not yet found any use in this material. Thus, it may be necessary to wait a long time before hearing about time crystals in quantum computing, technological developments, etc.
