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 and the quantum chaos ...
The results for the Grover algorithm are compared with the imperfection effects for quantum algorithms of quantum chaos maps where the universal law for the fidelity decay is given by the Random Matrix ...
From top to bottom, curves show data without GYQEC, with time fluctuating couplings, with GYQEC at l g = 1 (practically coincides with the previous curve) and at l g = 5, 10, 20. ...
