Quantum computing with photonic integrated circuits

One of the strong potentials of photonic quantum computing consist in the possibility to leverage matured technologies, currently implemented in several industrial domains. Integrated photonic, one of the most prominent, has already been implemented in proof of principle quantum computing platforms demonstrating its viability for high precision control of large number of qubits. Nevertheless, the tools required to generate, manipulate and detect single and entangled photons are not part of standard fabrication processes; such integrated elements still require extensive research work before integrated photonic circuit could be implemented in large scale systems. We present quantum computing protocols and a dedicated hardware architecture that takes advantage of photonic modularity and integrated photonic circuit with simplified architectures.
