(InnovationOrigins) A prototype of a quantum interface developed at the Institute for Science and Technology (IST) Austria, brings us one step closer to quantum internet by making possible the transfer of information from one quantum computer to another.
One problem with quantum computers is that the electronics only function at extremely low temperatures of a few thousands of a degree above absolute zero (-273.15 °C). If the temperature in the computer rises, all information is destroyed.
The researchers made use of entanglement, one of the basic principles of quantum mechanics. This describes a connection between two particles in which a change of state of one particle simultaneously leads to a corresponding change of the other particle. The phenomenon is already used in quantum cryptography for the secure encryption of data but is also suitable for use in microwave radiation.
The IST Austria physicists succeeded for the first time in generating entangled radiation with a mechanical object. The device could serve as an interface between quantum computers.
