Secure data transmission using quantum communication

This invention describes a method for securely sending information by first transmitting a random stream of bits using quantum entanglement. A second stream of bits is then sent, which acts as a guide, indicating to the recipient which parts of the random bit stream contain the actual message. This ensures only the intended recipient can reconstruct the valid data.

Why it matters: Since 2014, quantum communication hardware has advanced considerably, enabling more stable and longer-distance entanglement distribution. This makes practical implementation of such a system more feasible now.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedQuantum entanglement hardware, specialized optics
