The Global Centre for Risk and Innovation (GCRI)
Topics at Quantum Technologies: the pages in this section are listed below, each with its own scope and status.
The Quantum Technologies topics are the eight subject dossiers of its field, among them quantum computing, quantum sensing and quantum communications. Each dossier sets out how the risk develops, what is measured and in which units, the public sources and their licences, the methods, who decides and the limits of the evidence.
GCRI is a research, development and policy institution. It is not a regulator, and it does not certify, license or approve; its findings carry their methods and uncertainty.
The topics serve security managers, researchers and policy analysts. They separate the three technology families, computing, sensing and communications, then turn to post-quantum cryptography, materials, workforce, industry and responsible innovation. A reader looks for evidence of capability and for the transition steps that do not depend on it.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Logical qubit | A qubit encoded across many physical qubits using error correction. |
| Atomic clock | A clock that uses the frequency of an atomic transition as its reference. |
| Trusted node | A relay in a QKD network where keys exist in classical form and must be protected. |
| ML-KEM | A lattice-based key encapsulation mechanism standardised by NIST in FIPS 203. |
| Two-level system defect | A material defect that can absorb energy from a qubit and shorten its coherence. |
The bodies and documents this page is read against. Status and editions change; each link goes to the issuing body.

The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
