The quantum sensor sub-area uses individual particles, such as atoms and photons, to facilitate more sensitive detection than traditional measuring methods can achieve. The work will focus on developing quantum sensor technologies which are based on what are known as spin qubits or optomechanics. (Optomechanics is a combination of optics and nanomechanics.)In addition, completely new avenues will be researched by, for example, using materials in which the speed of light can be increased or reduced for greater measurement sensitivity. An important element also involves shifting the unavoidable measurement uncertainty to a variable other than the one you want to measure.
In the longer term, it is expected that there will be highly sensitive sensors for use in fields such as medicine
and that can be used to locate mineral deposits or warn about earthquakes or volcanic eruptions by extremely precise gravitational measurements.
The quantum sensor sub-area is led by Stefan Kröll, Professor of Atomic Physics, Lund University.
