Qubit Translation in a Quantum Computer

Across the world, teams of researchers are working on creating quantum computers. At the heart of a quantum computer’s power is the qubit, the information quanta similar to an electronic bit. Electrons are used as bits for the internal communication within a modern computer, and photons could be used similarly within a quantum computer. However, with all the teams working on different components and using different techniques, the photons emitted by one component may be useless to another piece of the quantum computer. Finally, researchers, at NIST, have discovered a way to transmute photons from different components and make them nearly indistinguishable. Using their device, a hybrid quantum computer, one that uses completely different internal hardware types, may be possible in the future.
