First On-Chip Nanoscale Optical Quantum Memory Developed（图）
On-Chip Nanoscale Optical Quantum Memory
2017/9/20
Quantum memory stores information in a similar fashion to the way traditional computer memory does, but on individual quantum particles—in this case, photons of light. This allows it to take advantage...
