Diraq has just published a landmark result in Nature Magazine: the demonstration that our qubits, manufactured in a foundry environment, consistently achieve over 99% fidelity in all quantum operations. This means that we’ll be able to use existing semiconductor foundries to put millions of qubits on a single chip, paving the way for compact, economical quantum computers that can be integrated into standard data centres.

Oxford Ionicshas successfully delivered and installed QUARTET, a full-stack trapped-ion quantum computer, at the National Quantum Computing Centre (NQCC). This significant deployment supports the development of commercial use cases for quantum computing, leveraging cutting-edge Electronic Qubit Control technology. QUARTET is designed for high performance and scalability, integrating all qubit control onto standard semiconductor chips. This unique architecture allows for field upgrades through easily swappable Quantum Processor Units, ensuring the NQCC can adapt to evolving computational demands without overhauling its infrastructure. As part of the UK’s Quantum Missions initiative, QUARTET will contribute to the Q-Surge project, enhancing 2D qubit connectivity in collaboration with industry partners. This marks a pivotal moment in quantum computing research and application. For the full article find the link via our comments. #QuantumComputing #OxfordIonics #NQCC

Our latest research reveals how simply changing the stacking orientation in bilayer semiconductor molybdenum disulfide (MoS₂) can dramatically enhance optoelectronic and electrochemical device performance by up to 100x! We show that: 1. 2H stacked bilayer MoS₂ shows 2 orders of magnitude higher photoresponsivity than 3R stacking 2. Up to 2x better hydrogen evolution reaction activity. This work demonstrates that "twist engineering" - controlling how atomic layers stack - is a powerful strategy for optimizing 2D materials without changing their chemical composition. The implications span from next-generation photodetectors to more efficient electrocatalysts for hydrogen production. Insightful research led by Irfan H. Abidi Vishnu Aggarwal Thank you to all our national and international collaborators!!

Scaling up spin-qubit quantum processors - using the ParityQC Architecture. In our new video, Florian Ginzel and Simanraj Sadana introduce one of the quantum hardware platforms we work with, semiconductor spin qubits, and share insights from our recent work on it. Last year, in collaboration with ARQUE Systems GmbH, we presented a version of the ParityQC Architecture specifically for quantum computers based on sparse grids of spin qubits.   Our latest breakthrough, replacement-type quantum gates, opens up even more possibilities for spin qubits, thanks to the novel gates’ ability to preserve noise bias and enable more efficient quantum error correction.
