NTT Develops Long-lived Quantum Memory

NTT, in partnership with Japan's National Institute of Informatics and Osaka University, announced a new approach in the development of a long-lived quantum memory that could be used in quantum computing. The research involves a superconductor diamond quantum hybrid system in which a dark state was shown to be 150 ns, an order of magnitude longer than previous attempts to hold state. By using a gap-tunable superconducting flux qubit, the researchers...

Toshiba Research, BT and ADVA Test ‘Quantum Leap’ Encryption

Toshiba Research Europe, BT, ADVA Optical Networking and the National Physical Laboratory (NPL), the UK’s National Measurement Institute, have tested Quantum Key Distribution (QKD) technology over a live fibre network. BT said the idea behind the trial is to leverage the principles of quantum mechanics in transmitting encryption key information. Any attempt to intercept the key can be identified, as it introduces anomalies which can be detected....
