Multiple steps toward the 'quantum singularity'

In early 2011, a pair of theoretical computer scientists at MIT proposed an optical experiment that would harness the weird laws of quantum mechanics to perform a computation impossible on conventional computers. Commenting ...

How do floating water bridges defy gravity?

The term "floating water bridge" may sound nonsensical, but it's the most logical name for a phenomenon that occurs when two beakers of water set slightly apart are zapped with high-voltage electricity and the water molecules ...

Detector blinding attacks on quantum cryptography defeated
