Quantum Photonics

Physicists have looked for deviations from standard quantum mechanics, testing whether quantum mechanics requires a more complex set of mathematical rules. A research team led by Philip Walther at the University of Vienna designed a photonic experiment using exotic metamaterials, which were fabricated at the University of California Berkeley. Their experiment supports standard quantum mechanics [...]

Quantum Teleportation in a Photonic Chip

Key circuits for quantum teleportation, which generate and detect quantum entanglement, have been successfully integrated into a photonic chip. These results from an international team of scientists from the universities of Bristol, Tokyo, Southampton and NTT Device Technology Laboratories open the door to developing ultra-high-speed quantum computers and strengthening the security of communication. Qubits, or [...]
