For the first time ever, scientists have just transferred quantum data between a solid crystal and a cold atomic gas, using photons. The new research can take us a step closer to developing functional quantum computers and even a quantum internet.
A team of researchers at the The Institute of Photonic Sciences (The Institut de Ciències Fotòniques or IFCO) in Spain achieved a hybrid quantum network link by passing the data between two types of storage “nodes” that were placed in different laboratories.
Previous studies have shown how quantum data can be transferred between identical nodes. The new study however, is the first time that such a data transfer has been achieved with a “hybrid” network of nodes. Passing quantum information between different nodes has previously posed a challenge to scientists as different nodes normally function at different wavelengths and bandwidths.
The research could help make it possible to develop quantum computers using …
