High-fidelity CNOT gate for spin qubits with asymmetric driving using virtual gates
High-fidelity CNOT gate for spin qubits with asymmetric driving using virtual gates
Recent experiments have demonstrated two-qubit fidelities above 99%, however, theoretically, the fidelity of CNOT operations is limited by off-resonant driving described by off-diagonal terms in the system Hamiltonian. Here we investigate these off-diagonal contributions and we propose a fidelity improvement of several orders of magnitude by using asymmetric driving. Therefore, …
