Quantum information processing


Though still in its infancy, quantum information science is nonetheless a rapidly advancing field of endeavor. Our areas of interest include fundamental questions in nonlocality, entanglement and quantum coherence. Present studies are directed towards solid-state superconducting nanoelectronics as a potential candidate for scalable quantum computing, and the application of quantum information processing to adaptive quantum networks.


Superconducting nanoelectronics

Nanoscale electronics is a rich and interdisciplinary field of investigation. Josephson junctions are a promising candidate for scalable quantum computation –  these systems are uniquely positioned at the borders of quantum and classical regimes, have well-characterized classical dynamics, and have been systematically investigated for evidence of macroscopic quantum coherence, entanglement and superposition. Future high-performance computing approaches hold the potential to incorporate Josephson junction-based flux qubit core processors into superconducting digital electronics such as rapid single flux quantum (RSFQ) logic and hybrid-technology multithreaded (HTMT)-derived architectures.


Adaptive
quantum networks

Quantum learning architectures have been suggested to offer new domains for quantum algorithm design. Machine learning-inspired architectures are self-organizing, robust, and ideal for such tasks as pattern recognition and associative processing. In International Journal of Theoretical Physics Vol. 43, No. 10 we introduce a novel model of superposed adaptive quantum networks, with considerations for high-dimensional dissipative quantum systems in quantum computation and molecular biology.
