Fidelity Analysis of Adiabatically Driven Donor Spins as Two-Qubit and Ququart Systems

Brian Michon, James Keppens, Ashutosh Kinikar +3

Donor spin systems host a native Hilbert space whose dimension exceeds that of a qubit, meaning they can be used as qudits. Here we study a \ce{Si{:}P} donor spin system through le…
