The global executive forum for
quantum infrastructure.
Established in 2010, ISIG is the trusted global platform fostering collaboration and driving innovation across the semiconductor and quantum industry — running influential regional summits across the U.S., Middle East, Europe and Asia, fully endorsed by local governments and leading companies throughout the supply chain.
The Mission
From prototype to
platform.
The Quantum Computing Infra Summit (QCIS) is the executive forum dedicated to the hardware, software and infrastructure challenges standing between today's quantum prototypes and tomorrow's utility-scale quantum platforms.
Organised by the International Semiconductor Industry Group (ISIG), QCIS brings together CTO-level executives from leading quantum hardware companies, foundry partners, cryogenic systems suppliers, cloud providers and government programme offices.
In 2026 the summit runs in two editions — Silicon Valley in April and Brussels in October — enabling the global quantum community to convene, benchmark progress and coordinate on the critical path to quantum utility.

EU Edition · Brussels, Belgium
Quantum Infra Summit EU
1–2 October 2026 · Brussels
The European edition broadens the scope to computing, sensing, and secure networks — the three pillars of quantum infrastructure critical to European strategic autonomy. Hosted in Brussels, the heart of EU institutions, the summit bridges the EU Quantum Flagship programme, NATO quantum sensing priorities, and post-quantum cryptography deployment across European critical infrastructure.
