Engineered magnetoconductance in InAs nanowire quantum dots [PDF]

open access: yes, 2015
Magnetoconductance is the change in the electrical transport properties of a solid state system in response to an applied magnetic field, determined by both its magnitude and orientation.

Implementation of Grover’s Algorithm & Bernstein-Vazirani Algorithm with IBM Qiskit

open access: yesJournal of Informatics and Web Engineering
Quantum logic gates differ from classical logic gates as the former involves quantum operators. The conventional gates such as AND, OR, NOT etc., are generally classified as classical gates, however, some of the quantum gates are known as Pauli gates ...

Fast non-Abelian geometric gates via transitionless quantum driving

open access: yes, 2015
A practical quantum computer must be capable of performing high fidelity quantum gates on a set of quantum bits (qubits). In the presence of noise, the realization of such gates poses daunting challenges.

Geometric quantum computation [PDF]

open access: yes, 2000
We describe in detail a general strategy for implementing a conditional geometric phase between two spins. Combined with single-spin operations, this simple operation is a universal gate for quantum computation, in that any unitary transformation can be ...

Electric circuits for universal quantum gates and quantum Fourier transformation

open access: yesPhysical Review Research, 2020
A set of universal quantum gates can be constructed based on quantum walk by formulating it as a scattering problem on a graph. In this paper, we simulate quantum gates by electric circuits, following a recent report that a one-dimensional LC electric ...

Realizing multi-qubit controlled nonadiabatic holonomic gates with connecting systems

open access: yesAAPPS Bulletin, 2022
Multi-qubit controlled gates are frequently used in quantum information processing. Although they can be built with gates from the universal set of one- and two-qubit gates, this procedure typically becomes very demanding as the number of such gates ...

Quantum circuit optimization for arbitrary high-dimensional bipartite quantum computation

open access: yesNew Journal of Physics
Implementation of high-dimensional (HD) quantum gates shows very promising perspectives for HD quantum computation. A bipartite quantum system with arbitrary dimensions n and m is termed a quNit–quMit.
