Effects of decoherence and imperfections for quantum algorithms
A. A. Pomeransky, O. V. Zhirov, D. L. Shepelyansky
We study effects of static inter-qubit interactions and random errors in quantum gates on the stability of various quantum algorithms including the Grover quantum search algorithm…

Quantum computation of the Anderson transition in presence of imperfections
Andrei A. Pomeransky, Dima L. Shepelyansky
We propose a quantum algorithm for simulation of the Anderson transition in disordered lattices and study numerically its sensitivity to static imperfections in a quantum computer.…

Strong superadditivity of the entanglement of formation follows from its additivity
Andrei Pomeransky
The additivity of both the entanglement of formation and the classical channel capacity is known to be a consequence of the strong superadditivity conjecture. We show that, convers…
