Efficient photonic operations for quantum networks

by Dr Mercedes Gimeno-Segovia (PsiQuantum)


Quantum networks use some of the same physical operations required for fault-tolerant photonic quantum computing architectures, in particular creation of entanglement between distict photonic states to enable all-photonic repeaters and efficient multiplexing to save resources of the quantum network. Generation of entanglement between dual-rail photonic states can be achieved through linear projective operators, using the principle of measurement-induced non-linearity. These processes are probabilistic, however it is possible to achieve efficiency far beyond what has been so far reported in the literature. Efficient switching networks enable an effective postselection of successful events, increasing the yield of the network. In this talk, I will present some of the recent progress on the design of efficient switching networks and high-probability entanglement-generating projective gates at PsiQuantum.
