Noise analysis for high-fidelity quantum entangling gates in an anharmonic linear Paul trap

The realization of high-fidelity quantum gates in a multiqubit system, with a typical target set at 99.9% is a critical requirement for the implementation of fault-tolerant quantum computation. To reach this level of fidelity, one needs to carefully analyze the noises and imperfections in the experimental system and optimize the gate operations to mitigate their effects. Here, we consider one of the leading experimental systems for the...
