Multidimensional Quantum Walks, with Application to k-Distinctness
Stacey Jefferey - QuSoft
While the quantum query complexity of k-distinctness is known to be O(n^{3/4−1/4(2k−1)}) for any constant k≥4, the best previous upper bound on the time complexity was ~O(n^{1−1/k}). We give a new upper bound of ~O(n^{3/4−1/4(2k−1)}) on the time complexity, matching the query complexity up to polylogarithmic factors. In order to achieve this upper bound, we give a new technique for designing quantum walk search algorithms, which is an extension of the electric network framework. We also show how to solve the welded trees problem in O(n) queries and O(n^2) time using this new technique, showing that the new quantum walk framework can achieve exponential speedups.
Seminar featuring Professor Richard Curry, University of Manchester
The ability to engineer the electrical, optical and magnetic properties of advanced materials on the nanoscale is of increasing importance to the development of future technologies. One approach to achieving this is through impurity doping, with increased control over the spatial resolution and isotopic purity enabled by the development of dedicated tools. In this talk the 'P-NAME' tool will be described, and the underlying principle surrounding its application for the development of doped systems for quantum technologies including qubits presented. cont.
