Testing Hyper-complex Quantum Theories With An Exotic Metamaterial

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 and allows the scientists to place bounds on alternative quantum theories. The results could help to guide theoretical work in a search for a more general version of quantum mechanics. [Read More]

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 quantum bits, are sensitive quantum versions of today’s computer 0’s and 1’s (bits) and are the foundation of quantum computers. [Read More]
