The Photonic Quantum Processor Program, led by Dr Alberto Peruzzo from RMIT University, will develop integrated single photon sources into complex photonic structures to produce and manipulate large-scale quantum states on chip. We will integrate arrays of quantum dots emitting at telecom wavelength with state-of-the-art high-speed, low loss switches and high-efficiency single photon detectors with the aim of generating quantum states of up to several tens of photons. This large photon state (N~20-40 photons) will be coupled to large multi-mode interferometers for demonstration of Scattershot BosonSampling, small-scale quantum simulators and algorithms, and testing fundamental aspects of quantum mechanics. Technological development will focus on robust fabrication of low-loss photonic waveguides, fast switches, on-chip filtering, engineered nonlinearities and superconducting detectors.
