Drive-Only Interaction Engineering via Dynamical Freezing
Songbo Xie, Jiheng Duan, Sabre Kais
Freezing is usually used to suppress unwanted dynamics, but it can also be used to engineer interactions. We introduce freezing-induced interaction engineering, a drive-only contro…

Measuring and correcting nanosecond pulse distortions in quantum-dot spin qubits
Jiheng Duan, Fernando Torres-Leal, John M. Nichol
Gate-defined semiconductor quantum dots utilize fast electrical control to manipulate spin and charge states of individual electrons. Electrical pulse distortions can limit control…

Mitigating Residual Exchange Coupling in Resonant Singlet-Triplet Qubits
Jiheng Duan, Fernando Torres-Leal, John M. Nichol
We propose methods to mitigate single- and two-qubit control errors due to residual exchange coupling in systems of exchange-coupled resonant singlet-triplet qubits. Commensurate d…
