Neutron interferometers have played an important role for precision measurements and fundamental physics. However, their size has been limited so far because they worked only if carved from a single piece of silicon crystal. 

To overcome this limit, a team from TU Wien, INRiM Turin and ILL Grenoble has recently succeeded in producing interferometers from two separate crystals; a real feat made possible by using a high-precision tip-tilt platform developed and realized at INRiM for the crystal alignment. 

This result opens up new possibilities for quantum measurements, and will allow to investigate fundamental interactions such as, for example, the sensitivity of neutrons to gravity in the quantum regime and to hypothetical new forces with unprecedented accuracy.

The results of the research were published on July 15, 2022 in the Journal of Applied Crystallography.
