Abstract The sensitivity of non-local optical measurements at low light intensities, such as those involved in long-baseline telescope arrays1,2, is limited by fundamental quantum noise and photon losses3. Distributed quantum entanglement has been proposed as a route towards overcoming these limitations and accessing new regimes of non-local optical sensing4,5,6.

2 days ago On February 11 the most concrete action Bitcoin developers have ever taken toward protecting the world's largest cryptocurrency from quantum computers was announced. The Bitcoin core developer Murch posted in his X account: "BIP 360: Pay to Merkle Root was published." The proposal is now formally …

Editor’s summary Quantum computers can outperform classical computers at certain tasks and offer guaranteed security in terms of information communication. However, they are unlikely to be available as individual devices any time soon. Blind quantum computing would allow clients to run their algorithms on quantum servers that are housed in larger facilities without giving away any information about the requested task. Wei et al.
