Reduced sensitivity to charge noise in semiconductor spin qubits via symmetric operation

MD Reed, BM Maune, RW Andrews, MG Borselli… - Physical review …, 2016 - APS
We demonstrate improved operation of exchange-coupled semiconductor quantum dots by
substantially reducing the sensitivity of exchange operations to charge noise. The method …

Methodology of resonant equiangular composite quantum gates

GH Low, TJ Yoder, IL Chuang - Physical Review X, 2016 - APS
The creation of composite quantum gates that implement quantum response functions U^(θ)
dependent on some parameter of interest θ is often more of an art than a science. Through …

High-fidelity quantum gates via optimizing short pulse sequences in three-level systems

C Zhang, Y Liu, J Song, Y **a, ZC Shi - New Journal of Physics, 2024 - iopscience.iop.org
We propose a robust and high-fidelity scheme for realizing universal quantum gates by
optimizing short pulse sequences in a three-level system. To alleviate the sensitivity to the …
