Abstract

For many quantum optical experiments it is essential to have ultimate control over the propagation of light. In quantum optics interference of quantum states is often studied using linear optical circuits. These circuits are usually realised in free-space setups or by integrated photonics, which provide a low loss platform for investigating quantum interference. Yet, these require a close-to-perfect implementation of the setup and it remains a major challenge to include adaptive elements.
