CQT’s public group directory yielded 34 group profiles, single-sourced from the official directory in October 2026. Summing the profiles gives 149 PhD students and 97 postdoc-level researchers, but this is not a unique-person headcount: the Computer Science group is an umbrella that overlaps named PI groups, and affiliates are included. Per-lab paper counts are not published on a comparable basis, and qubits are not allocated per group — both are addressed below.
Click a column header to sort. A zero means no such person is currently listed on the public profile, not independently verified absence.

Qubits at CQT are not allocated one fixed number per group, and unlike counts cannot be added into one total. The credible claims separate into what runs now, what is being built, and what researchers reach remotely.
CQT owns and operates its established 20-qubit platform. careers.nus.edu.sg
Scale-up of the superconducting platform; to be accessible to external users. careers.nus.edu.sg
Ytterbium and barium ions; hosted at CQT/NUS for the National Quantum Processor Initiative. No operational qubit count stated. cqt.sg
Caesium atoms; setups at NUS and NTU. No operational qubit count stated. cqt.sg
Defect-free Rydberg atom arrays for quantum simulation, built and operated at CQT. cqt.sg
A 3-qubit trapped-ion machine operated in the lab. cqt.sg
CQT researchers run experiments via Singapore's National Quantum Computing Hub; H2 has been used at 56 qubits. cqt.sg
Installation expected to be completed in 2026 under the NQO-Quantinuum partnership. cqt.sg
CQT researchers have used IBM systems through the cloud (e.g. 27-qubit IBM-Auckland, 5-qubit IBM-Lima) and IonQ (11 qubits). cqt.sg
The 216 publication-related claims found for named CQT people and groups mix lifetime totals (e.g. “more than 140 research papers” for Vlatko Vedral in a 2008 annual report), isolated single-paper announcements (such as the 2026 Nature atomic-clock paper from Murray Barrett’s team), group pages whose “recent papers” lists cover different periods (Yvonne Gao’s page lists three 2024 papers; Rainer Dumke’s most recent listed paper is from 2019), and third-party coverage. Some matches are not even CQT Singapore — TU Eindhoven’s “Coherence and Quantum Technology” group shares the acronym.
A meaningful comparison would require a defined window (for example calendar 2025), author disambiguation, and a bibliometric database query. Examples of the heterogeneity: cqt.sg, cqt.sg, cqt.sg, cqt.sg
Method: 34 group profiles scraped from CQT’s official public directory (cqt.sg), scanned October 2026; staffing is a live-directory snapshot, not payroll data. Postdocs counts people in research-fellow roles only. Hardware and access claims drawn from 166 structured claims across CQT pages, NUS job postings, lab sites and press; duplicate press echoes of the same system were collapsed and historical cloud-access demos before 2020 were cut for space. Per-lab paper counts were not reportable from 216 heterogeneous publication claims.
