Quantum Physics and Mechanics

Quantum Technology

Quantum technology is a new arena of engineering and physics. In quantum technology transitions some of the properties of quantum mechanics, especially quantum superposition, quantum entanglement and quantum tunnelling, into practical applications such as quantum sensing, quantum computing, quantum simulation, quantum cryptography, quantum imaging and quantum metrology. Quantum superposition states can be very sensitive to many external effects, such as electric, magnetic and gravitational fields; rotation, acceleration and time, and therefore can used to make very accurate sensors. Quantum secure correspondences are the methods which are anticipated to be 'quantum safe' in the approach of a quantum processing frameworks that could break current cryptography frameworks. One significant component of a quantum secure communication systems is expected to be Quantum key distribution, or 'QKD': a method of transmitting information using entangled light in a way that makes any interception of the transmission obvious to the user.
