Computational leakage: Grover's algorithm with imperfections
Pil Hun Song, Ilki Kim
We study the effects of dissipation or leakage on the time evolution of Grover's algorithm for a quantum computer. We introduce an effective two-level model with dissipation and ra…

Uncertainty rescued: Bohr's complementarity for composite systems
Ilki Kim, Guenter Mahler
Generalized uncertainty relations may depend not only on the commutator relation of two observables considered, but also on mutual correlations, in particular, on entanglement. The…

Quantum network architecture of tight-binding models with substitution sequences
Ilki Kim, Guenter Mahler
We study a two-spin quantum Turing architecture, in which discrete local rotations α_m of the Turing head spin alternate with quantum controlled NOT-operations. Substitution sequen…
