Quantum Teleportation Is Real, Here’s How It Works
Researchers have developed devices based on silicon photonic microcircuits that can use the features of quantum physics to generate and manipulate individual particles of light in programmable nanochains..
Quantum computers can potentially solve problems that are not even modern supercomputers can do it, as well as ensure the absolute security of the transmitted information. However, this technology is based on quantum information in the form of encoded elementary particles that are difficult to control and measure.
Scientists from the University of Bristol, together with colleagues from the Danish Technical University, have demonstrated for the first time the successful teleportation of the quantum state of a photon between two programmable microcircuits..
During the experiment after measuring the particle, the team achieved the simultaneous destruction of the connection of its quantum entanglement and transfer of this state to another particle located on the receiving chip. The accuracy of teleportation was quite high and amounted to 91%.
Despite all the complexity and quirkiness of these technologies, researchers have recently been able to integrate quantum states into ordinary electronic devices and control them using electricity.
