Physicists have created a confusion between atom and molecule

A group of physicists from China and the United States created the first controlled quantum entanglement between the cooled atoms and the molecule. The experiment demonstrates a method of creating microscopic hybrid systems for quantum information processing. Work published in the journal Nature.

Classic computing devices that convert information from different physical media for the processing, storage and transmission of data. It is likely that the quantum processing of information, which is produced with the help of quantum computers will also make use of different physical media in the problems of computing, simulation and Metrology.

The basic elements of quantum computers are qubits — microscopic system that can be controlled with the help of macroscopic devices. As qubits are artificial or real atoms. In different implementations of quantum computers qubits frequencies differ by orders of magnitude, so if you use different platforms for quantum computation it is necessary to develop a system to link incompatible frequency qubits.

A group of physicists from the USA and China under the leadership of Dr James Chin-Wen Chou (James Chin-wen Chou) proposed the use of molecules, in which there is a set of transitions with frequencies from a few kilohertz up to several terahertz, as a mediator for communication of various physical qubits. Apart from the fact that molecules have various internal energy levels, they also rotate and vibrate, allowing you to use even higher frequencies up to hundreds of terahertz.
