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…

Modeling of flopping-mode spin qubits: beyond the two-site model
Ashutosh Kinikar, Vukan Levajac, Kristof Moors +3
We present a flexible modeling framework for flopping-mode spin qubits that captures the spatial structure of the double-well confinement and magnetic-field-gradient profile going…

Three components of stochastic entropy production associated with the quantum Zeno and anti-Zeno effects
Ashutosh Kinikar, Ian J. Ford
We investigate stochastic entropy production in a two-level quantum system that performs Rabi oscillations while undergoing quantum measurement brought about by continuous random d…
