SUMMARY:Quantum BC Seminar Series - Dr. James Brown
DESCRIPTION:Quantum BC Seminar Series Tuesday\, January 13\, 2026 at 1:30pm BC Time with Dr. James Brown \nPlease note the earlier start time at 1:30pm \n  \nTitle: Empowering Quantum Research and Education: New Algorithmic Approaches and the qBraid Platform. \nAbstract:\nThis talk presents recent advances in quantum computing research at qBraid alongside practical tools designed to accelerate both research and education in quantum computing. The first half of the talk will explore three cutting-edge research directions that address key challenges in quantum algorithms and molecular simulation. These include 1)An onion quantum reservoir computing (QRC) architecture for time-series prediction\, inspired by classical echo state networks. By simultaneously evolving multiple quantum reservoirs that capture different temporal scales through controlled eigenvalue spectrum manipulation\, we achieve superior performance in predicting aluminum alloy degradation under varying environmental conditions while maintaining shallow circuit depths suitable for current NISQ devices. 2)Improvements to the Generalized Superfast Encoding (GSE)\, a Fermion-to-qubit mapping designed for molecular Hamiltonians. Through path optimization\, multi-edge graph structures for enhanced error detection\, and efficient stabilizer measurement frameworks\, our approach significantly outperforms traditional mappings like Jordan-Wigner and Bravyi-Kitaev. 3) We examine Hamiltonian transformations inspired by Qubit Coupled Cluster (QCC) methods that generate Clifford transformations deterministically. These techniques produce efficient classical approximations with accuracy between MP2 and CISD while significantly reducing entanglement\, enabling improved DMRG calculations and low-depth VQE circuits with reduced CNOT counts. The second half of the talk will feature a live demonstration of the qBraid platform\, which provides seamless access to GPUs\, CPUs\, and QPUs\, alongside qBook—an interactive\, web-based notebook environment designed to transform quantum computing education. These tools lower barriers to entry for students and researchers across the Quantum BC consortium institutions\, enabling hands-on exploration of quantum algorithms and immediate implementation of cutting-edge research techniques. \n  \nBio : I am a research scientist and software developer who develops and implements methods to calculate properties of materials using both classical and quantum/ quantum-inspired algorithms. I have published about methods to calculate a broad range of material properties including molecular vibrations\, vibronic dynamics and electronic structure. \n  \nGoogle Scholar (https://scholar.google.com/citations?user=q0R3tm8AAAAJ&hl=en) \nOpen-Source Software developed from research.\nTangelo (https://github.com/goodchemistryco/Tangelo)\nTDDFTinversion (https://github.com/brownj42/TDDFTinversion) \nJoin on Zoom: https://ubc.zoom.us/j/69443327772?pwd=TGhhTXFIQ3ZiUmNrN0pUa3FObTNydz09 \nMeeting ID: 694 4332 7772 Passcode: 996727 \n
