Researchers from Yale University for the first time in the history of science demonstrated the possibility of teleporting not only quantum information, but also the state of the quantum logic element, each of which was represented by a separate quantum bit, a qubit.

This capability, carried out at a strictly defined and fully controlled point in time, opens a new way for creating a new architecture of modular quantum computers, to which, if necessary, it will be possible to connect additional modules, increasing the processing power of these systems.

Naturally, the key moment in this achievement is the phenomenon of quantum teleportation, which has already been used more than once to transfer a quantum state (information) from one object to another.

Using a protocol theoretically developed back in the 1990s, the Yale researchers transmitted not only quantum information but also a quantum function without conducting any direct physical impact on the objects involved.

Quantum logic elements, qubits, which contain a certain computational function, are necessary for the realization of this kind of quantum computing, which are performed by many small systems that are united into a single network.

According to the existing theory, such an architecture will avoid the occurrence or easily compensate for errors that somehow arise with the operation of quantum processors. In addition, the modular architecture will make it possible in the future without great difficulty to create large and complex computing systems.

Separate modules of the quantum system should be maximally isolated from one another in order to prevent their mutual influence. The same isolation, on the other hand, makes it as difficult as possible to exchange data between individual modules, and the teleportation of quantum functions is that wand that helps to circumvent this problem.

In addition to teleporting the quantum function, the Yale researchers have created in their system circuits with additional qubits, which allow to detect and immediately correct errors.
