Query: Integrated optomechanics and single-photon detection in diamond photonic
  integrated circuits   The development of quantum computers and quantum simulators promises to
provide solutions to problems, which can currently not be solved on classical
computers. Finding the best physical implementation for such technologies is an
important research topic and using optical effects is a promising route towards
this goal. It was theoretically shown that optical quantum computing is
possible using only single-photon sources and detectors, and linear optical
circuits. An experimental implementation of such quantum optical circuits
requires a stable, robust and scalable architecture. This can be achieved via
miniaturization of the optical devices in the form of photonic integrated
circuits (PICs). The development of a suitable material platform for such PICs
could therefore have a large impact on future technologies. Diamond is a
particularly attractive material here, as it naturally offers a range of
optically active defects, which can act as single-photon sources, quantum
memories, or sensor elements. Besides its excellent optical properties, diamond
also has a very high Young's modulus, which is important for optomechanics, and
can be employed for potentially fast and low-loss tuning of PICs after
fabrication. In this work, components for future quantum optical circuits are
developed. This includes the first diamond optomechanical elements, as well as
the first integrated single-photon detectors on a diamond material platform.
Diamond micromechanical resonators with high quality factors are realized and
their actuation via optical gradient forces and electrostatic forces is
demonstrated. The accomplished superconducting nanowire single-photon detectors
show excellent performance in terms of low timing jitter, high detection
efficiency, and low noise-equivalent power. Moreover, a novel scalable method
for PIC fabrication from high quality single crystal diamond is presented.
