Abstract
Solid-state spin qubits are a promising platform for quantum computation and quantum networks. Recent experiments have demonstrated high-quality control over multi-qubit systems, elementary quantum algorithms and non-fault-tolerant error correction. Large-scale systems will require using error-corrected logical qubits that are operated fault-tolerantly so that reliable computation becomes possible despite noisy operations.
Overcoming imperfections in this way remains a major outstanding challenge for quantum science. In this talk, I will present our recent results on the fault-tolerant operation of a logical qubit using spin qubits in diamonds. Our approach is based on the 5-qubit code with a recently discovered flag protocol that enables fault-tolerance using a total of seven qubits. We demonstrate fault-tolerant encoding, gate operations and non-destructive stabilizer measurements for a logical qubit of a quantum error correction code.
Bio
Mohamed Abobeih is a postdoctoral researcher in the Taminiau Lab at QuTech. In 2015 he obtained a joint masters degree in Photonics from Karlsruhe Institute of Technology, Aix-Marseille University, and The Institute of Photonic Sciences (Barcelona).
In 2016 he joined the Taminiau Lab as a PhD student. There, he developed novel methods to control complex nuclear-spin systems coupled to the electron spin of a nitrogen-vacancy centre in diamond and used these for applications in quantum sensing and quantum information processing. In 2020 he received the Kavli Delft Publication Prize.
QuTech360
QuTech360 is a series of seminars that will help you build a 360-degree understanding of the research carried out at QuTech. In each seminar, a quantum expert will guide us through one of the main topics studied in their group. While our next seminar is approaching, you can check out the previous talks on YouTube.
