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…

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…
