SQMS Study Links Qubit Performance to Material and Fabrication Features

Curated by Shubham · TechCapsules · Oct 5, 2026

AI-summarised brief · reviewed before publication

Fermilab‑led SQMS researchers studied 22 superconducting transmon qubits, employing seven materials‑characterization methods and quantum coherence measurements. They identified oxide thickness, etched sidewall angles, and trench depth as key factors linked to performance, explaining up to a two‑fold variation among devices. The collaborative effort, involving Northwestern, Rigetti, NIST, Ames, NIST, and the National Physical Laboratory, published findings in Applied Physics Reviews, offering concrete correlations between microscopic material features and qubit coherence.

💡 Why It Matters

· By pinpointing specific fabrication variables that govern qubit performance, the study supplies a practical roadmap for engineers to reduce variability, accelerating the development of scalable, reliable quantum processors.

Second QDA Forum Focuses on Real-World Deployments And Progress of Quantum Computing

Leaders from classical and quantum computing gathered at the second Quantum Datacenter Alliance (QDA) Forum in London’s Battersea Power Station to accelerate fault‑tolerant quantum integration with high‑performance computing (HPC) and AI infrastructures. Speakers from NVIDIA, IBM, Coherent, Equinix, Quantinuum, Atom Computing, DSIT, Nu Quantum and others shared lessons from real‑world deployments, emphasizing that system‑level architecture, control, error correction, interoperability and power consumption are now as critical as qubit performance. The event highlighted existing partnerships that are already delivering commercial use cases such as high‑precision molecular modelling and foreign‑exchange trading optimisation. Attendees called for open sharing and collaborative standards to build scalable, reliable quantum infrastructure, and announced plans for future forums and working groups to sustain momentum toward utility‑scale quantum computers.

💡 Demonstrating interoperable quantum‑HPC hybrids proves the technology can move beyond labs, unlocking immediate value for sectors like finance and drug discovery.

India demonstrates first 5.56 km free-space Quantum Key Distribution link: Know what…

India’s research teams have completed a successful free‑space quantum key distribution (QKD) trial spanning 5.56 km, the longest such link demonstrated in the country to date. The experiment used photon‑based encryption transmitted between two ground stations without fiber optics, confirming that quantum keys can be exchanged reliably over atmospheric distances. Engineers reported a quantum bit error rate within acceptable limits and continuous key generation throughout the test period. The achievement follows similar demonstrations worldwide and aligns with India’s national roadmap to develop quantum communication infrastructure for secure data transmission. Officials said the result paves the way for scaling to satellite‑based QKD and integrating quantum‑safe links into critical networks.

💡 It proves India can build indigenous, long‑range quantum links, a prerequisite for deploying secure satellite communications that protect sensitive governmental and commercial data.

IBM Expands Research Collaborations with IISc and IIT Bombay to Advance Quantum-Centric…

IBM has broadened its research ties with India’s Indian Institute of Science and IIT Bombay, extending collaborations first launched in 2018 and 2021. The new agenda targets quantum‑centric supercomputing workflows, hybrid Quantum‑HPC algorithms, agentic AI and sovereign Indic language models. At IISc, IBM Research India and faculty are co‑designing quantum subspace iteration methods that blend classical approximation‑tolerant diagonalization with IBM quantum processing units, aiming to boost efficiency on cloud‑native supercomputing clusters. At IIT Bombay, teams will refine large‑language‑model runtimes and adapt multimodal AI for Indian languages while building sovereign AI infrastructure. The collaborations also include PhD programs, shared testbeds for quantum‑classical co‑execution, and open‑source toolkits that will be released through IBM’s cloud platform to accelerate adoption across research labs. The joint effort leverages IISc’s computational science, IIT Bombay’s AI systems expertise and IBM’s hardware and hybrid‑cloud stack to support national technology initiatives.

💡 By marrying quantum‑HPC advances with sovereign AI capabilities, the partnership gives India a home‑grown pathway to high‑performance computing that sidesteps reliance on foreign cloud services.

Silicon Quantum Computing and Schneider Electric Advance Energy Grid Forecasting via Watermelon…

Silicon Quantum Computing and Schneider Electric entered Stage 2 of the Australian Government’s Critical Technologies Challenge Program, receiving A$3.6 million to deploy hybrid quantum‑classical machine learning across distributed energy resource networks. The partnership, led by UNSW Sydney, uses SQC’s Watermelon™ quantum feature generator to enhance classical forecasting models. Stage 1 trials showed a 20% average accuracy boost, peaking at 41%, for next‑day energy predictions over a year. Stage 2 will roll out the system to hundreds of Australian homes, embedding quantum‑generated features into Schneider’s production AI pipelines.

💡 The project demonstrates that quantum‑enhanced models can materially improve grid forecasting, potentially reducing energy waste and supporting renewable integration. It marks a rare, large‑scale deployment of quantum technology in a commercial utility setting.
