University of Geneva University of Calgary, and two groups of researchers has successfully produced a practical solid-state quantum memory device , the ethereal capture quantum entanglement in solid-state within the crystal. This will make quantum computing and quantum communication more feasible. Long-distance quantum computing and quantum transport is a key component of the memory, before the photon is difficult to store, and use quantum states excited atom cloud storage requires large equipment and professional staff, making the quantum memory is difficult to achieve.

University of Calgary research team led by Wolfgang Tittel entangled photons will be imported coated with thulium ions and the lithium niobate crystal into quantum superposition states, when the thulium ion shock absorbing photons at different frequencies after some processing, vibration After 7 ns to synchronize and replicate the same entangled state of a photon. Nicolas Gisin University of Geneva used a similar approach and different crystals. In the next through some means of regulation is likely to extend their time from 7 nanoseconds to seconds.
