Stabilization of Quantum Computer Calculation Basis by Qubit Encoding in Virtual Spin Representation
A. R. Kessel
It is proposed to map the quantum information qubit not to individual spin 1/2 states, but to the collective spin states being eigenfunctions of the Hamiltonian including spin-spin…
Schemes of implementation in NMR of quantum processors and Deutsch-Jozsa algorithm by using virtual spin representation
Alexander R. Kessel, Natalia M. Yakovleva
Schemes of experimental realization of the main two qubit processors for quantum computers and Deutsch-Jozsa algorithm are derived in virtual spin representation. The results are a…
Quantum entanglement and classical separability in NMR computing
Alexander R. Kessel, Vladimir L. Ermakov
In the discussion about the quantumness of NMR computation a conclusion is done that computational states are separable and therefore can not be entangled. This conclusion is based…
Delocalized Qubits as a Computational Basis in the System of Interacting Spins
Alexander R. Kessel, Vladimir L. Ermakov
It is suggested to map the qubits into solid state NMR spin system collective states instead of the states of the individual spin. Such an approach introduces the stable computatio…
Three-Qubit Gate Realization Using Single Quantum Particle
Alexander R. Kessel, Vladimir L. Ermakov
Using virtual spin formalism it is shown that a quantum particle with eight energy levels can store three qubits. The formalism allows to realize a universal set of quantum gates.…
Four Atomic Optical Energy Levels as a Two Qubit Quantum Computer Register
Vladimir L. Ermakov, Alexander R. Kessel, Vitaly V. Samartsev
It is proposed to use four atomic optical energy levels as a two qubit quantum register. A single Pr3+ atom in a monocrystal LaF3 subjected to resonant laser irradiation is used as…
