Quantum Key Distribution
Quantum cryptography provides a secure means for distributing secret keys between two parties (usually referred to as Alice and Bob) on an optical network. A unique feature of the technique is that the secrecy of the keys is independent of the resources available to a hacker.
Applications in quantum information technology, such as quantum cryptography and quantum computing, require new devices that generate and detect light at the quantum level. Toshiba have developed a generic nanotechnology for single photon generation and detection using semiconductor quantum dots.
