Recently, atom-like impurities in diamond (colour centers) have emerged as an exceptional system for quantum physics in solid state. In this talk I will discuss recent developments transforming quantum control tools into quantum technologies based on single colour centers. Specially, realization of quantum optical interface between spins and photons and scalable quantum registers in diamond will be presented. New applications of diamond qubits involving nanoscale magnetic resonance and force measurements will be shown. I will discuss single spin NMR paving the way to ultrasensitive MRI and structure determination of single biomolecules. The detection of proteins using nanodiamond sensors will be presented. I will also highlight future directions of research including combination of quantum error correction and sensing protocols and quantum enabled sensing and imaging in living cells.

I will argue for and against possibilities to experimentally test the interface between quantum physics and gravity in a meaningful way. One promising route has been opened by massive mechanical objects that are now becoming available as new systems for quantum science. Devices currently under investigation cover a mass range of more than 17 orders of magnitude - from nanomechanical waveguides of some picogram to macroscopic, kilogram-weight mirrors of gravitational wave detectors. This provides access to a hitherto untested parameter regime of macroscopic quantum physics, eventually at the interface to gravity. My conclusion is therefore going to be an optimistic one.
