TITLE: Quantum control in silicon qubits creating high fidelity gates in the presence of errors and physical constraints
ABSTRACT: Quantum computers using the spins of electrons trapped in quantum dots at a semiconductor dielectric interface as their qubits are a promising platform because of the small size of the qubits and the well-developed industry around fabrication of semiconductor devices. However, spin qubit devices in silicon are hampered by errors such as those caused by charge noise. Additionally, it has been difficult to scale these devices to larger numbers of qubits because of factors like crosstalk. Consequently, this proposal lays out a plan to expand quantum control methods able to create high fidelity operation in the presence of crosstalk, charge noise and other challenges. The goal of this proposal is to move towards larger arrays of qubits with high fidelity operations, such that more interesting quantum computing calculations can be made in semiconductor qubit devices.
