    Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States
    Hybrid Event

    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 lies […]

    QUIEST Seminar: “Breaking No-Go Theorems in Quantum Walks”

    /

    Hybrid Event

    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 as […]
