Major step ahead for cryptography

Imagine you could work out the answer to a question, without knowing what the question was. For example, suppose someone thinks of two numbers and then asks another person to work out their sum, without letting them know ...

Secure computers aren't so secure

(PhysOrg.com) -- Even well-defended computers can leak shocking amounts of private data. MIT researchers seek out exotic attacks in order to shut them down.

First-ever calculation performed on optical quantum computer chip

(PhysOrg.com) -- A primitive quantum computer that uses single particles of light (photons) whizzing through a silicon chip has performed its first mathematical calculation. This is the first time a calculation has been performed ...

Researchers make breakthrough in the quantum control of light

Researchers at UC Santa Barbara have recently demonstrated a breakthrough in the quantum control of photons, the energy quanta of light. This is a significant result in quantum computation, and could eventually have implications ...
