Quantum photonic group develops quatum sensors based on diamond Jan 29, 2019
Prof. dr. Milos NESLADEK
IMO-IMOMEC not only makes very pure diamonds as a very hard coating for drilling tools, etc.. Professor Milos Nesladek's quantum photonics group creates very small and very sensitive sensors to measure electric fields, magnetic fields, variations in temperature, pressure and movement, with this base product.
In the pure diamond, the physicists build an artificial impurity consisting of one or several atoms, sometimes called color centers. This impurity becomes the so-called sensor core, with which the variations in an electric or magnetic field are measured. The purer the diamond itself, the more sensitive the sensor inside.
Physicists can build in individual color centers. For example, they replace two adjacent carbon atoms (diamonds are nothing else) by a nitrogen atom and an empty place in the crystal lattice of the stone. In this way they form a magnetic dipole, which in turn behaves like a qubit, the quantum physical equivalent of the classical bit.
