Physicists report that they were able to achieve quantum teleportation with silicon photon chips. The chip-to-chip quantum teleportation is expected to bring new prospects and make it possible to create other technological breakthroughs.

Yet, a number of theoretical and technical barriers stand in the way of building full-fledged quantum computers. Quantum computers are seen a key to solving today’s too complex problems which can not be handled by existing most powerful supercomputers. Moreover a quantum internet could protect the information from malicious attacks in a better way. But all these advancements rely on “quantum information” which is typically encoded in a single quantum particle that is extremely difficult to control and measure.

The experiment was conducted by scientists from the University of Bristol in collaboration with the Technical University of Denmark. They have developed devices based on silicon chips, capable of generating and manipulating individual particles of light in programmable nanoscale circuits. Taking advantage of the quantum entanglement phenomenon, it was possible to conduct quantum teleportation between two microcircuits by transferring the state of a quantum particle from one to the other.
