The advantages of the photons makes optical quantum system ideally suited for fundamental quantum physics experiments and a variety of applications in quantum information processing. Here I will briefly review privacy-preserving photonic quantum cloud computing, where quantum information is securely communicated and computed. Related to this I will discuss new experimental insights into the verification of quantum computer and quantum simulators. Based on the utilization of integrated waveguides I will also present new results on resource-efficient intermediate quantum computing utilizing the Bosonic nature of photons.

As outlook I will briefly discuss the current status of new fundamental quantum experiments that aim to test the interface between quantum mechanics and general relativity. As a first step we aim to probe jointly the quantum superposition principle and the mass-energy equivalence for photons (i.e. massless particles) by utilizing a rotating fiber-interferometer. In the future we aim to exploit a precise interferometer to observe gravitationally induced phase shifts for probing the quantum complementarity principle and gravitational time dilation.
