Buying Time With Blockchains
Theoretical Physicists at New Zealand’s Victoria University are studying the first quantum blockchain. Quantum entanglement is typically studied based on entanglement across space. The new concept involves quantum entanglement in time. Past transactions (in time) are stored in quantum states, again, across time. Tampering is impossible as the entangled photons from earlier — in time — no longer exist. It’s a quantum time machine. Interesting and understandable read from IEEE SPECTRUM. April 23, 2018.
