Recently, quantum sensing has become a distinct and rapidly growing branch of research within quantum nanotechnology. The field is providing new opportunities, especially with regard to high sensitivity and precision.
The Hardware of Quantum Sensors are ‘Quantum Circuits’ composed of ‘QuBit’ Devices.
QuBit devices can be constructed from
a_Natural Atoms (e.g. NMR, Ion-Trap, Quant Dot Spin Qubits),
b_‘Artificial’ atoms (e.g. superconductive Qubits) and
c_Photons (Photonic QuBits).
The quantum phenomena (superposition, entanglement, coherence) in QuBit devices are very fragile to outside interference.
In quantum computers our best is done to overcome fragility as a weakness for the entanglement of a large enough number of QuBits,
i.e. for developing Quantum Computers with Quantum Supremacy.. Quantum Sensors capitalize on this fragility to achieve extra-
ordinary sensitivity.
Recently, quantum sensors have been developed e.g. for 1. brain scanning, 2. virus-detection, 3. underwater or underground GPS, etc. with unprecedented performance and low cost.
This course will review the foundations of Quantum Sensing, the Quantum Sensing Protocol, and the Atomic, Artificial Atomic, and Superconducting QuBit based Quantum Sesnors, with special emphesis on the applications in Information Technology and Bionics.
