Abstract
For decades, one of the expeditions of quantum physics has been to build a quantum computer that can process large-scale, challenging computational problems exponentially faster than classical computers. While scientists and engineers are progressing toward this target, almost every part of a quantum computer still needs noteworthy Research and Development (R&D). Current research is focusing on every angle of the quantum computer problem, including:
• innovative ways to generate entangled photon pairs,
• inventive types of gates and their fabrication on chips,
• superior ways to create and control qubits,
• novel designs for storage/memory buffers,
• effective detectors, and
• Creative ways to optimize them in various architectures.
Optimizing the waveguide geometry, integrated quantum optical circuits are constructed to realize single-photon quantum computing. The central elements for such circuits include sources, gates and detectors. However, a major missing function critical for photonic quantum computing on-chip is a buffer, where single photons are stored for a short period of time to facilitate circuit synchronization. As a significant step in the field, an all-optical integrated quantum processor is being developed at the National Institute of Quantum Computing (NIQC).
For fault-tolerant quantum computing, the speech will explore the frontier of current quests for quantum processing of ultra-high security, integrating the following enabling techniques including
• probabilistic Bayesian network,
• quantum filtering,
• Error Correction Code (ECC), and
• Riemannian geometry.
