Architecture

The NQIT Hub’s hardware development effort is guided by detailed and continually updated plans for the system’s architecture.

The Hub’s core proposition is that networking together quantum systems makes for a powerful and flexible information processing platform. Architectural theory and modeling must specify the performance requirements for the nodal devices, and should determine how best they can perform core operations such as entanglement purification, where we upgrade the fidelity of a connective link by using it several times and filtering. Similarly it is essential to identify the requirements for the network’s connective fabric, such as tolerable photon loss rates, switching requirements, detector efficiency and dark count rates, as well as assessing the benefits of introducing advanced components such as photonic memories.
