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…

Understanding oxide-thickness-dependent variability in dense Si-MOS quantum dot arrays
Arne Loenders, Jacques Van Damme, Clement Godfrin +19
Achieving uniform and scalable control of semiconductor spin qubits remains a key challenge for large scale quantum computing. In this work, we investigate how gate oxide thickness…
