Time-dependent exactly solvable models for quantum computing
A. A. Suzko, Grigori Karlovich Giorgadze · Physics of Particles and Nuclei Letters · 2008
A time-dependent periodic Hamiltonian admitting exact solutions is applied to construct a set of universal gates for a quantum computer. The time evolution matrices are obtained in an explicit form and used to construct logic gates for computation. A way of obtaining an entanglement operator is discussed, too. The method is based on transformation of soluble time-independent equations into time-dependent ones by employing a set of special time-dependent transformation operators.
