Errors due to finite rise and fall times of pulses in superconducting charge qubits
Sangchul Oh · Physical review. B, Condensed matter · 2002
We study numerically the dynamics of two-qubit gates with superconducting charge qubits. The exact ratio of ${E}_{J}$ to ${E}_{L}$ and the corresponding operation time are calculated in order to implement two-qubit gates. We investigate the effect of finite rise and fall times of pulses in realization of two-qubit gates. It is found that the error in implementing two-qubit gates grows quadratically in rise and fall times of pulses.
