GQI's 2026 predictions noted that the proportion of quantum processors shipped for on-premises usage continues to rise. The drivers are data sovereignty, latency, and the security requirements of regulated industries.

On-premises quantum hardware means an organisation owns or leases a quantum system that sits in their facility rather than accessing quantum computation through a cloud API. The practical barrier has been cost and maintenance expertise. But as systems become more reliable and vendors develop managed on-premises offerings, the calculus is shifting for financial services, healthcare, and defence organisations that cannot route sensitive computations through external cloud services.

The data sovereignty driver is straightforward in regulated industries. A hedge fund running portfolio optimisation on external cloud quantum hardware is potentially exposing trading strategy. On-premises removes that risk

Latency matters for time-critical applications. Cloud quantum access introduces network round-trip delays that may be acceptable for research workloads but not for real-time decision support

The managed on-premises model where the vendor provides hardware, maintenance, and software support changes the expertise barrier. You do not need a team of quantum engineers, you need a service contract

IBM's Quantum System Two was designed partly with on-premises deployment in mind. The cryogenic system in a modular format that can fit in a standard data centre environment rather than requiring bespoke infrastructure

The on-premises trend mirrors what happened with AI inference. Cloud-first became hybrid became on-premises-preferred for sensitive workloads. Quantum is following the same pattern with a few years of lag
