We may be a step closer to unhackable quantum Wi-Fi thanks to a chip that could establish wireless communication between a wide range of quantum devices.
Quantum communication systems have a distinct advantage over the wireless and fibre-based networks that we use now: they are incredibly hard to hack. This is because they use the quantum states of objects like particles of light to encode and transmit information – those states allow for more complex encryption and can easily reveal if they have been tampered with.
