Grover search under localized dephasing

D. Reitzner, M. Hillery

Decoherence in quantum searches, and in the Grover search in particular, has already been extensively studied, leading very quickly to the loss of the quadratic speedup over the cl…

The Helstrom measurement: A nondestructive implementation

Rui Han, Gerd Leuchs, János A. Bergou

We discuss a novel implementation of the minimum error state discrimination measurement, originally introduced by Helstrom. In this implementation, instead of performing the optima…

Near optimal discrimination of binary coherent signals via atom-light interaction

Rui Han, János A. Bergou, Gerd Leuchs

We study the discrimination of weak coherent states of light with significant overlaps by nondestructive measurements on the light states through measuring atomic states that are e…

Duality games and operational duality relations

Emilio Bagan, John Calsamiglia, Janos A. Bergou +1

We give operational meaning to wave-particle duality in terms of discrimination games. Duality arises as a constraint on the probability of winning these games. The games are playe…

Finding paths with quantum walks or quantum walking through a maze

Daniel Reitzner, Mark Hillery, Daniel Koch

We show that it is possible to use a quantum walk to find a path from one marked vertex to another. In the specific case of stars connected in a chain, one can find the path fr…

Sequential discrimination of qudits by multiple observers

Mark Hillery, Jihane Mimih

We discuss a scheme in which sequential state-discrimination measurements are performed on qudits to determine the quantum state in which they were initially prepared. The qudits b…
