Crosstalk analysis for single-qubit and two-qubit gates in spin qubit arrays

Scaling up spin qubit systems requires high-fidelity single-qubit and two-qubit gates. Gate fidelities exceeding $98\%$ were already demonstrated in silicon based single double quantum dots, whereas for the realization of larger arrays crosstalk effects on neighboring qubits must be taken into account. We analyze impacted by when performing operations neighbor with a simple Heisenberg model. Furthermore we propose conditions driving fields to robustly synchronize Rabi oscillations avoid effects. In our analysis also consider next nearest show that synchronization leads restricted choice field strength, exchange interaction, thus gate time. Considering realistic experimental set parameter values perform nearly crosstalk-free CNOT so open pathway scalable computing devices.
