Dynamically corrected gates for a singlet-triplet qubit

POSTER

Abstract

Spin qubits in quantum dots are a promising candidate for quantum information processing due to their long coherence and potential for scalability. However, hyperfine and charge noise in host semiconductor heterostructures make it challenging to achieve high-fidelity single- and two-qubit gates in these devices. Here, we report experimental work on implementing dynamically corrected gates in a Si/SiGe double quantum dot, which are designed to correct errors arising from hyperfine field fluctuations. We demonstrate dynamically corrected identity and Hadamard gates for a singlet-triplet qubit with high-fidelity.
