How NOT to build control-target gates in semiconductor quantum dots and beyond
Roman Korol, John Nichol, Ignacio Franco
Universal quantum computation requires single-qubit control together with at least one entangling two-qubit gate. CNOT and CROT gates are two famous examples of such gates, wherein…
Phase locking nuclear spins in silicon with spin-orbit coupling
Habitamu Y. Walelign, Manas Ranjan Sahu, John M. Nichol
Because they have such long coherence times, nuclear spins have extraordinary potential for use in quantum information processing devices. However, coherent nuclear spin control ge…
Stochastic trajectories and excursions in a double quantum dot system
Guilherme Fiusa, Pedro E. Harunari, Alberto J. B. Rosal +2
We investigate the trajectory-level stochastic dynamics of a double quantum dot system using the formalism of stochastic excursions. An excursion is a sub-trajectory that begins wh…
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…
Spin qubit shuttling between coupled quantum dots with inhomogeneous Landé g-tensors
Zhi-Hai Liu, Xiao-Fei Liu, H. Q. Xu
By utilizing the site-dependent spin quantization axis in semiconductor quantum dot (QD) arrays, shuttling-based spin qubit gates have become an appealing approach to realize scala…
Multi-level charge fluctuations in a Si/SiGe double quantum dot device
Dylan Albrecht, Feiyang Ye, N. Tobias Jacobson +1
Discrete charge fluctuations, routinely observed in semiconductor quantum dot devices, may contribute significantly to device drift and errors resulting from qubit miscalibration.…
