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…
Sdim: A Qudit Stabilizer Simulator
Adeeb Kabir, Steven Nguyen, Sohan Ghosh +5
Quantum computers have steadily improved over the last decade, but developing fault-tolerant quantum computing (FTQC) techniques, required for useful, universal computation remains…
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…
Current Conservation in the Self-Consistent Josephson Junction
Simon Krekels, Vukan Levajac, Kristof Moors +2
Conventional treatments of Josephson junctions (JJs) are typically not current-conserving. In the mean-field BCS theory, current conservation is only guaranteed if the superconduct…
Optimization of Floquet fluxonium qubits with commensurable two-tone drives
Joachim Lauwens, Kristof Moors, Bart Sorée
Protecting superconducting qubits from low-frequency noise by operating them on dynamical sweet-spot manifolds has proven to be a promising setup, theoretically as well as experime…
