quantumcomputer chip based on spin qubits in diamond uses modules that are entangled with on-chip optical links. This enables an increased connectivity and a negligible crosstalk and error-rate when the number of qubits increases onchip. Here, 3D integration is the key enabling technology for a large-scale integration of the diamond spin qubits with photonic and electronic circuits for routing, control and readout of qubits. There are several engineering challenges to integrate the large number of spins in diamond with the on-chip circuits operating at a cryogenic temperature. In this paper we will address challenges, present recent results and discuss future outlook of the integration technology for realization of a scalable quantumcomputer based on diamond spin qubits.

An ultrafast electrically-pumped VECSEL design requires an acceptable trade-off in cw output power. Validating our design guidelines and simulations 120 mW cw output power are generated. Homogenous current injection is even achieved for large devices.
We analyze the sources of polarization transformation for single photons in a Space-to-Earth quantum communication link, particularly the satellite pointing system, giving an estimate of the effect and discussing poss...
