Qudit is a multi-level computational unit alternative to the conventional 2-level qubit.
Compared to qubit, qudit provides a larger state space to store and process information, and …

Solving linear systems of equations is a common problem that arises both on its own and as
a subroutine in more complex problems: given a matrix A and a vector b→, find a vector x→ …

This article outlines our point of view regarding the applicability, state-of-the-art, and
potential of quantum computing for problems in finance. We provide an introduction to …

Computational chemistry is an essential tool in the pharmaceutical industry. Quantum
computing is a fast evolving technology that promises to completely shift the computational …

We point out a general framework that encompasses most cases in which quantum effects
enable an increase in precision when estimating a parameter (quantum metrology). The …

The superposition principle plays the most central role in all considerations of quantum
information, and in most of the" gedanken" experiments and even the paradoxes of quantum …

Consider a Boolean function x: X→{0, 1} that partitions set X between its good and bad
elements, where a is good if x (a)= 1 and bad other-wise. Consider also a quantum …
