(PhysOrg.com) -- Currently, the data stored in classical digital memories such as CDs, DVDs, and barcodes is read by classical light. But as a new study shows, using quantum light to read these classical memories can bring ...
(PhysOrg.com) -- To improve transmission speeds, the Internet has transitioned over the years from one using copper to fiber optic cabling. Unfortunately, this has caused a bottleneck to occur where the light signals meet ...
Quantum teleportation is a technique allowing the transfer of quantum information between two distant quantum objects, a sender and a receiver, using a phenomenon called quantum entanglement as a resource.
