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…

Qudit vs. Qubit: Simulated performance of error correction codes in higher dimensions
James Keppens, Quinten Eggerickx, Vukan Levajac +2
Qudits can be described by a state vector in a -dimensional Hilbert space, enabling a more extensive encoding and manipulation of information compared to qubits. This implies th…
