Quantum internet breakthrough after ‘quantum data’ transmitted

Quantum ComputingA new quantum computing study claims that a recent finding in the production, storage and retrieval of “quantum data” has brought us one step closer to the quantum internet.

Currently, quantum information is unstable over long distances and quantum bits, or qubits — the carriers of quantum information — are easily lost or fragmented during transmission.

Classical computer bits are transmitted today as pulses of light through fiber optic cables using devices called “repeaters” to amplify signals across the length of the network. To transmit qubits over longer distances the way classical computer bits are transmitted today we need similar devices that can store and retransmit quantum states across the whole network, ensuring signal fidelity no matter how far the data has to go.
