DOI: 10.1088/1402-4896/ade377

Abstract: Grover’s quantum algorithm can find a marked item from an unstructured database faster than any classical algorithm, and hence it has been used for several applications such as cryptanalysis and optimization. When there exist multiple… read more here.

DOI: 10.1103/physreva.101.032346

Abstract: Grover's quantum search algorithm provides a quadratic speedup over the classical one. The computational complexity is based on the number of queries to the oracle. However, depth is a more modern metric for noisy intermediate-scale… read more here.

DOI: 10.1103/physreva.96.012329

Abstract: In various applications one is interested in quantum dynamics at intermediate evolution times, for which the adiabatic approximation is inadequate. Here we develop a quasi-adiabatic approximation based on the WKB method, designed to work for… read more here.

DOI: 10.1364/oe.532364

Abstract: We present a low-resource and robust optical implementation of the four-dimensional Grover coin, a four-port linear-optical scatterer that augments the low dimensionality of a regular beam-splitter. While prior realizations of the Grover coin required a… read more here.
