We like phat pipes, and we cannot lie. And over the past 20 years we’ve seen internet connections change from dial-up to ADSL over copper wire, to today’s fibre-optics. So what’s next for how we transfer data?
Imagine a network that, instead of using pulses of light to send signals, uses the properties of photons themselves. This is a quantum network, and it relies on something Einstein wasn’t very fond of: quantum entanglement. Decried as ‘spooky action at a distance’ by the moustachioed relativity-theoriser, entanglement means creating a pair of photons in such a way that, when you measure the quantum state of one, you immediately know the same property of the other no matter how far apart they are. Transferring information in this way is known as quantum teleportation,…
