Workflow from Scientific Research

The sequence for the estimation of the initialization fidelity of the qubit register with four sequential gate sequences of native multi-qubit gates between the electron and nuclear spin qubits: randomize, measure, initialize and measure. Randomization of the nuclear spin register is performed by initializing the electron spin into a mixed state and performing SWAP gates between the electron and nuclear spins via adiabatic EDSR. Measurement involves controlled- rotations of the electron spin conditional on the total nuclear spin state, followed by a measurement of the electron spin. The initializtion step involves initialization of the electron spin followed by SWAP gates between the electron and each of the nuclear spins.
