Quantum computers [1–4] are explicitly quantum mechanical systems that use phenomena
such as superposition and entanglement to perform computational tasks more efficiently …

The existence of quantum correlation (as revealed by quantum discord), other than
entanglement and its role in quantum-information processing (QIP), is a current subject for …

We review the theoretical and the experimental researches aimed at quantifying or
identifying quantum correlations in liquid-state nuclear magnetic resonance (NMR) systems …

We present the NMR implementation of a recently proposed quantum algorithm to find the
parity of a permutation. In the usual qubit model of quantum computation, it is widely …

The Redfield master equation was solved analytically for a nuclear system with spin I= 7/2.
Using the irreducible tensor operator basis, the solutions of each density matrix element …

We discuss methods of quantum state tomography for solid-state systems with a large
nuclear spin I= 3/2 in nanometer-scale semiconductors devices based on a quantum well …

We have found that the NMR coherence lifetime T 2 of the symmetric central±1 2→∓ 1 2
transition for O 17 nuclei through a π pulse train can be extended by over two orders of …

Nuclear magnetic resonance is viewed as an important technique for the implementation of
many quantum information algorithms and protocols. Although the most straightforward …

This report experimentally demonstrates that the theoretical background of the atom–field
scenario points out that the NMR quadrupolar Hamiltonian works as an effective …

This chapter reviews the present state of the art in using the endohedral fullerenes N@ C 60
and P@ C 60 as qubits in a spin quantum computer. After a brief introduction to spin …
