ECCN 4A906
NSRSATQuantum computers and related electronic assemblies, and components therefor, as follows .
What This ECCN Covers
ECCN 4A906 controls quantum computers and related "electronic assemblies" and "components," as defined in the entry — broadly, systems exceeding thresholds tied to parameters such as qubit count and gate error rate. Added in a September 2024 interim final rule to align with allied controls, it carries a worldwide license requirement for National Security, Regional Stability, and Anti-Terrorism reasons.
Who needs to check this?
Developers and exporters of quantum computers, cryogenic control assemblies, and qubit hardware, and the research institutions that acquire them.
Compliance tip
This is a recent, worldwide control — check the current entry for the qubit and gate-error thresholds, and review License Exception IEC (and the related general license for certain foreign nationals) before relying on any exception. Software and technology are controlled separately under 4D906 and 4E906.
Items Covered
- a.Quantum computers, as follows:
- 1. Quantum computers supporting 34 or more, but fewer than 100, 'fully controlled', 'connected' and 'working' 'physical qubits', and having a 'C-NOT error' of less than or equal to 10−4;
- 2. Quantum computers supporting 100 or more, but fewer than 200, 'fully controlled', 'connected' and 'working' 'physical qubits', and having a 'C-NOT error' of less than or equal to 10−3;
- 3. Quantum computers supporting 200 or more, but fewer than 350, 'fully controlled', 'connected' and 'working' 'physical qubits', and having a 'C-NOT error' of less than or equal to 2 × 10−3;

Control Reasons
Items controlled for national security reasons under multilateral export control regimes.
Items controlled for regional stability reasons.
Items controlled for anti-terrorism reasons. Most items on the CCL have AT controls.
