Quantum Entanglement and Quantum Computational Algorithms
Arvind
The existence of entangled quantum states gives extra power to quantum computers over their classical counterparts. Quantum entanglement shows up qualitatively at the level of two…
Quantum Computing by Two-Dimensional NMR using Spin- and Transition-Selective Pulses
T. S. Mahesh, Kavita Dorai, Arvind +1
Quantum computing using two-dimensional NMR has recently been described using scalar coupling evolution technique [J. Chem. Phys.,109,10603 (1998)]. In the present paper, we descri…
Implementation of a Deutsch-like quantum algorithm utilizing entanglement at the two-qubit level, on an NMR quantum information processor
Kavita Dorai, Arvind, Anil Kumar
We describe the experimental implementation of a recently proposed quantum algorithm involving quantum entanglement at the level of two qubits using NMR. The algorithm solves a gen…
A two-qubit algorithm involving quantum entanglement
Arvind, N. Mukunda
The phenomenon of quantum entanglement is fundamental to the implementation of quantum computation, and requires at least two qubits for its demonstration. However, both Deutsch al…
Generalised coherent states and the diagonal representation for operators
N. Mukunda, Arvind, S. Chaturvedi +1
We consider the problem of existence of the diagonal representation for operators in the space of a family of generalized coherent states associated with an unitary irreducible rep…
