However, their size has been limited so far because they worked only if carved from a single piece of crystal. Since the 1990s, attempts have also been made to produce interferometers from two separate crystals\u2014but without success. Now a team from TU Wien, INRIM Turin and ILL Grenoble has achieved precisely this feat, using a high-precision tip-tilt platform for the crystal alignment. This opens up completely new possibilities for quantum measurements, including research on quantum effects in a gravitational field.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Particles can move as waves along different paths at the same time\u2014this is one of the most important findings of quantum physics.
