The quantum computer is a class of physical devices that can perform high-speed mathematical and logical operations and that can store and process quantum information following the laws of quantum mechanics. From: Nanomaterials and Devices, 2015 ...
focusing on why there is often a quantum speedup in the number of basis functions over classical mean-field methods. Next, we analyze the overheads associated with measuring quantities of interest on a quantum computer and introduce more efficient ...
(Arute et al.,2019). In an artificial experiment, they were able to demonstrate that a programmable quantum device could solve a problem that a classical computer could not solve in a feasible amount of time. However, the task solved by Google ‘s quantum computer was custom tailored to ...
Comparison of velocity U between the full-order model (a) and the reduced-order model solutions (b). Figure 7. Cumulative energies of the obtained POD base vectors. The first 95 POD bases vectors have a cumulative energy above 99.9%, which means that the rest of the base vectors can be...
A computation on a quantum computer works by preparing a superposition of computational states. A quantum circuit, prepared by the user, uses operations to generate entanglement, leading to interference between these different states, as governed by an algorithm. Many possible outcomes are canceled out...

Universal quantum computers are potentially an ideal setting for simulating many-body quantum dynamics that is out of reach for classical digital computers. We use state-of-the-art IBM quantum computers to study paradigmatic examples of condensed matter
We investigate the relation between the speed of quantum NOT gate and the asymmetry or detuning of the potential in system of the interaction of a two-level rf-SQUID qubit with a classical microwave pulse. The rf-SQUID is characterized by an asymmetric double well potential that gives rise to...
Quantum computing promises to offer substantial speed-ups over its classical counterpart for certain problems. However, the greatest impediment to realizing its full potential is noise that is inherent to these systems. The widely accepted solution to th
