Satellite study proves global quantum communication will be possible

Researchers in Italy have demonstrated the feasibility of quantum communications between high-orbiting global navigation satellites and a ground station, with an exchange at the single photon level over a distance of 20,000km. The milestone experiment proves the feasibility of secure quantum communications on a global scale, using the Global Navigation Satellite System (GNSS). It is...

Quantum is key to securing blockchain, say Russian researchers

Although blockchain is traditionally seen as secure, it is vulnerable to attack from quantum computers. Now, a team of Russian researchers has developed a solution to the quantum-era blockchain challenge, using quantum key distribution (QKD). Writing in the journal Quantum Science and Technology, the researchers set out a quantum-safe blockchain platform that uses QKD to...
