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 ...

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.

Researchers test quantum encryption hacking risk

(Phys.org) —Quantum communication systems offer the promise of virtually unbreakable encryption. Unlike classical encryption, which is used to send secure data over networks today and whose security depends on the difficulty ...

Beefing up public-key encryption

Most financial transactions on the Internet are safeguarded by a cryptographic technique called public-key encryption. Where traditional encryption relies on a single secret key, shared by both sender and recipient, public-key ...
