Easy Control over Fermionic Computations
Yuri Ozhigov
Quantum fermionic computations on occupation numbers proposed in quant-ph/0003137 are studied. It is shown that a control over external field and tunneling would suffice to fulfill…

Quantum Computer with Fixed Interaction is Universal
Yuri Ozhigov, Leonid Fedichkin
It is proved that a quantum computer with fixed and permanent interaction of diagonal type between qubits proposed in the work quant-ph/0201132 is universal. Such computer is contr…

Implementation of Quantum Fourier Transform and Simulation of Wave Functions by Fixed Interaction
Yuri Ozhigov
We study a quantum computer with fixed and permanent interaction of diagonal type between qubits. It is controlled only by one-qubit quick transformations. It is shown how to imple…
