Orientational Quantum Revivals

QuantumProposalAll_woanot.jpg

Our collaborators in Duisburg have proposed a quantum experiment in which the interference of the superposed orientations of a freely falling nanorotor leads to revivals of the particle’s initial alignment. Realising this experiment will enable quantum enhanced torque sensing and tests of objective collapse models in the rotational degrees of freedom.
