Quantum Summit
Quantum Summit
World Technology Forum — Quantum Summit
Three quantum computing companies went public within a single year, Washington began writing nine-figure cheques to pick its own national champions, and Google's Willow chip proved that adding more qubits can now reduce errors instead of adding them. The Quantum Summit convenes the hardware makers, cloud platforms and governments racing to turn that lab result into a computer worth owning.

Physical qubits in IBM's Condor — the largest superconducting processor deployed
Quantum computing is still an early-revenue industry riding a long-horizon economic thesis. The gap between today's numbers and 2040's is precisely what makes it a Summit topic rather than a settled market.
BCG concentrates that value in drug discovery, financial modelling, materials science and logistics optimisation. Other estimates run lower on narrower hardware-and-software revenue definitions — roughly $170–200B by 2040 per BlueQubit and SpinQ Quanta — a reminder that, as with gaming and AI, the range reflects differing scope rather than disagreement about direction.
IBM, Google and Rigetti lead on raw qubit count; Quantinuum and IonQ lead on gate fidelity — the two most mature, most heavily funded modalities.
QuEra, Pasqal, Atom Computing and Infleqtion are scaling fastest by qubit count; PsiQuantum and Xanadu are betting on silicon-photonic paths to fault tolerance.
DARPA's Quantum Benchmarking Initiative, the US National Quantum Initiative, the EU Quantum Flagship and China's state programme are now openly picking strategic winners.
NIST's finalised post-quantum standards are driving a "harvest now, decrypt later" migration deadline across banking, government and telecoms infrastructure.
Three of the field's most heavily funded hardware makers reached public markets within months of each other in 2026. Quantinuum — the Honeywell-backed trapped-ion leader that holds the record for verified logical qubits (48, on its Helios processor) — listed on Nasdaq under QNT in June following a $600 million raise at a $10 billion valuation, with analysts expecting it to price above $20 billion. Infleqtion, the neutral-atom specialist, completed a SPAC merger onto NYSE as INFQ in February, the first publicly traded neutral-atom company. Xanadu, the photonic-computing pioneer, followed with a Nasdaq/TSX SPAC merger as XNDU in March. They join the long-established public pure-plays IonQ (NYSE: IONQ), Rigetti (NASDAQ: RGTI) and D-Wave (NYSE: QBTS). In parallel, the US government moved from research grants to strategic procurement: DARPA's Quantum Benchmarking Initiative awarded roughly $1 billion to IBM, $375 million to chip foundry GlobalFoundries, and $100 million each to D-Wave, Rigetti, PsiQuantum, Quantinuum, Atom Computing and Infleqtion — Washington effectively naming its own quantum champions.
Thirty-six hardware makers, cloud platforms, national programmes, standards bodies and iBANK's own quantum initiatives — spanning every qubit modality in commercial development. Filter by category, or search by name.
Qubit counts, funding figures and valuations reflect the most recently reported technical milestones, financing rounds or credible 2025–2026 industry estimates, compiled from public filings, press releases and trade coverage including The Quantum Insider, Quantum Zeitgeist, company investor communications and DARPA/NIST public announcements. Figures for private or pre-listing entities may not reflect a completed transaction. Compiled for Summit convening purposes as of September 2026 and not intended as investment research.
Four threads run through the Quantum Summit programme, each mapped to the institutions in the directory above.
Superconducting, trapped-ion, neutral-atom, photonic and silicon-spin approaches, each with a different bet on how the field reaches fault tolerance.
Azure Quantum, Amazon Braket and a growing layer of algorithm and application software making early hardware usable today.
DARPA, the US National Quantum Initiative, the EU Quantum Flagship and national champions in the UK, China and India.
NIST's standards and the migration deadline they set for every institution holding data an adversary might decrypt later.
