  • QUIEST PhD & Postdoc Seminar

    Singh 313 3205 Walnut Street, Philadelphia, PA, United States

    Presentation by: Vatsal Bandaru, PhD student in ESE   Talk Title: Two-Dimensional Conveyor-Mode Shuttling Scheme for Scaling Si/SiGe Spin Qubit Architectures   Description: Existing two-dimensional spin-qubit matrices are not easily scalable. Individually controllable gate electrodes require immense signal overhead, resulting in a signal fan-out problem. Additionally, short-range exchange interactions are unsuitable for coupling distant qubits,...

  • Physical Chemistry Seminar: “Locality as a Design Variable at Interfaces”

    Carolyn Hoff Lynch Lecture Hall (Chemistry Complex) 433 South University Avenue, Philadelphia, Pennsylvania

    Sarah King Assistant Professor of Chemistry, University of Chicago Research Synopsis: The King Lab at the University of Chicago seeks to uncover how interfaces and nanoscale material heterogeneity determine the ultrafast dynamics, properties, and functionality of materials. Interfaces and boundaries between materials, phases, and structural motifs influences material suitability for applications such as photovoltaics or...

  • QUIEST Seminar: Gurudev Dutt (UPitt): “Towards Macroscopic Superpositions with Levitated Diamond Crystals”

    Raisler Lounge (Towne 225) 107 Towne Building, Philadelphia, PA, United States

    Abstract: Nitrogen-vacancy (NV) centers in diamond offer a "uniquely quantum handle" for controlling mechanical systems. While NV-based sensing in bulk diamond has reached high levels of maturity —enabling applications from in vivo thermometry in biological systems and characterizing local magnetic environments in quantum materials to nanoscale EPR spectroscopy of individual surface spins— a new frontier...

  • Condensed and Living Matter Seminar: “Epitaxially engineered hybrid materials for quantum technologies”

    David Rittenhouse Lab, 2N3 209 S 33rd St, Philadelphia, PA, United States

    Nitin Samarth Verne M. Willaman Professor of Physics & Professor of Materials Science/Engineering, Penn State University Research Synopsis: The synthesis of complex epitaxial quantum materials allows the exploration of emergent phenomena arising from the interplay between factors such as electron-electron correlations, broken symmetry, spin-orbit coupling, electron-phonon coupling, and topological order. This provides exciting opportunities for...

  • QUIEST Seminar: Christino Tamon (Clarkson University): “Breaking No-Go Theorems in Quantum Walks”

    Raisler Lounge (Towne 225) 107 Towne Building, Philadelphia, PA, United States

    Abstract: A continuous-time quantum walk on a graph is given by the unitary matrix exp(-itA) where A is the adjacency matrix of the graph. This defines a Schrodinger evolution with A as the Hamiltonian. In quantum computing, quantum walk is important for designing fast quantum algorithms (such as Grover search) and useful quantum protocols (such...
