Interference-free measurement conditions at the nanoscale
At the Centre for Applied Quantum Technology (ZAQuant) at the University of Stuttgart, four decoupled precision measurement chambers provide ideal conditions for measurements at the nanoscale. Through careful planning and optimisation, Müller-BBM Industry Solutions minimises magnetic and mechanical interference, thereby enabling high-precision quantum sensing.

Initial situation
The Centre for Applied Quantum Technology (ZAQuant) on the University of Stuttgart campus required highly specialised research conditions for quantum sensors. The particular challenge lay in the close spatial integration of various research areas, coupled with extremely high requirements for minimising magnetic fields and vibrations.

Mission
Müller-BBM Industry Solutions played a key role in the design of the precision measurement rooms. The aim was to use appropriate designs and forecasts to create an environment in which even the slightest external influences would not affect the research results.

Measurement
The measurements and forecasts include effective magnetic field shielding and special vibration-isolated foundations that significantly reduce external and internal influences. These vibration-isolated foundations consist of concrete blocks weighing 150 tonnes each, which, in principle, rest on six air cushions. One of the precision laboratories was additionally encased in a double-layered shell made of aluminium and mu-metal.
In the acceptance tests, the target design criteria for vibrations in the order of VC‑M (≤ 12 nm/s) and for magnetic fields of < 5 nTeff were clearly achieved.
Result
The result is four high-precision measurement chambers that are situated in close proximity to one another but are virtually completely isolated from one another. This allows various experiments at the nanoscale to be carried out in parallel under stable conditions. The vibration and magnetic field levels achieved during the acceptance tests are among the lowest in the world, enabling research of the highest standard.
