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…

Moving quantum agents in a finite environment
Ilki Kim, Guenter Mahler
We investigate an all-quantum-mechanical spin network, in which a subset of spins, the ``moving agents'', are subject to local and pair unitary transformations controlled by th…

Correlation between Correlations: Process and Time in Quantum Networks
Guenter Mahler, Ilki Kim
We study a special inhomogeneous quantum network consisting of a ring of pseudo-spins (here ) sequentially coupled to one and the same central spin under the influence o…
