The article introduces a novel manufacturable platform for photonic quantum computing, emphasizing its potential for practical applications. It details a benchmarking process for silicon photonics-based modules that generate, manipulate, and detect photonic qubits, achieving remarkable fidelity levels. Key metrics include 99.98% state preparation and measurement fidelity, along with successful qubit interconnects exceeding 99.72% fidelity. The paper also outlines next-generation technologies, such as low-loss waveguides and efficient detectors, aimed at minimizing loss and enhancing operational efficiency in quantum systems.
We benchmark a set of monolithically-integrated silicon photonics-based modules to generate, manipulate, network, and detect heralded photonic qubits, demonstrating dual-rail photonic qubits with 99.98% state preparation and measurement fidelity.
Our manufacturable platform addresses the challenges of photonic quantum computing by integrating high-fidelity components that can be produced at scale, thus pushing the field closer to practical applications.
Next-generation technologies such as low-loss silicon nitride waveguides and high-efficiency photon-number-resolving detectors will help tackle the problem of loss and enable further advancements in quantum computing.
Conditional on photon detection and ignoring loss, we achieve chip-to-chip qubit interconnects with 99.72% fidelity, showcasing the potential for robust networking in photonic quantum systems.
