About · QCIS Series

The global executive forum for
quantum infrastructure.

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 · Leuven, Belgium

Quantum Infra Summit EU

1–2 October 2026 · Leuven

The European edition broadens the scope to computing, sensing, and secure networks — the three pillars of quantum infrastructure critical to European strategic autonomy. Hosted at IMEC Headquarters in Leuven, the summit bridges the EU Quantum Flagship programme, NATO quantum sensing priorities, and post-quantum cryptography deployment across European critical infrastructure.
