Influence of random telegraph noise on quantum bit gate operation

We consider the problem of analyzing spin-flip qubit gate operation in presence Random Telegraph Noise (RTN). Our compressive approach is following. By using Feynman disentangling operators method, we calculate probability driven by different kinds composite pulses, e.g., Constant pulse (C-pulse), Quantum Well (QW-pulse), and Barrier Potential (BP-pulse) RTN. When pulses RTN act x-direction z-direction respectively, optimal time to achieve perfect qubit. report that highest fidelity can be achieved C-pulse, followed BP-pulse QW-pulse. For a more general case, have tested several sequences for achieving high quantum gates, where use acting directions. From calculations, find when QW-pulse, BP-pulse, C-pulse x-direction, y-direction, z-direction, respectively. extend our investigations multiple QW BP while choosing amplitude constant The results calculation show 98.5% throughout course may beneficial error correction.
