Quantum computing is a novel method of computation that uses the principles of quantum
mechanics to handle highly challenging situations in a very short amount of time. Quantum …

The possibility of integrating quantum computation in a traditional system appears to be a
viable route to drastically improve the performance of systems endowed with artificial …

Grover search algorithm provides a quadratic speedup over all classical algorithms for
unstructured data search. The origin of this quantum advantage has been explored and …

Rydberg atoms possess long coherence time and inherent scalability, which makes it
promising to implement quantum algorithms. An exact and robust quantum search algorithm …

We introduce and explore the notion of texture of an arbitrary quantum state, in a selected
basis. In the first part of this Letter we develop a resource theory and show that state texture …

Finding the minimum value in an unordered database is a common and fundamental task in
computer science. However, the optimal classical deterministic algorithm can find the …

The development of quantum information technology demands precise engineering and
control of quantum states at the single-atom level. Recent advances in electron spin …

Quantifying entanglement is an important issue in quantum information theory. Here we
consider the entanglement measures through the trace norm in terms of two methods, the …

The resolution of NP-hard problems, including the traveling salesman problem and graph
coloring, continues to be a major hurdle in computational science. While traditional …

Healthcare systems widely use information technology (IT) for system authentication (digital
signatures), web surfing, e-mails, instant messaging, protecting data at rest, Voice over …
