Invention Reference Number
This technology introduces a new approach for the generation of continuous variable cluster states for measurement-based quantum computing in a compact and scalable optical system. It leverages a different degree of freedom to reduce the required quantum resources needed for scalability by using independently addressable spatial modes to multiplex sources of entangled light into a single source while maintaining performance. The approach supports the development of practical implementations of quantum systems as it reduces required quantum resources, thus helping advance scalable quantum computing and sensing applications.
Description
This invention introduces a photonic architecture that generates continuous variable cluster states using cascaded parametric amplifiers arranged in a multi-stage configuration. By leveraging a sequence of optical amplification processes in a controlled and adaptable configuration, the system produces entangled quantum states while reducing the number of independent sources of entangled states typically required with conventional methods. The design incorporates spatial mode structuring to enable a more compact footprint and improved scalability compared to traditional approaches.
The approach supports deterministic generation of quantum states and leverages an additional degree of freedom to improve scalability. By distributing the state generation process across multiple stages and implementing spatial multiplexing, the system relaxes performance bottlenecks that can limit scalability. The architecture is adaptable to different configurations, allowing integration into a range of photonic platforms while supporting the generation of cluster states with different connectivity.
