US Quantum Export Controls Explained in Plain English

Updated 2026-10-11 | 4 min read | QUANTUM (QNT) community

Why countries control exports of quantum technology

Quantum computing is an unusual technology: it is mostly published science, yet some of the hardware and know how could help a rival military. Export controls are the tool governments use to slow the flow of the most sensitive pieces without shutting down science. In the United States the main agency is the Bureau of Industry and Security (BIS) inside the Commerce Department. This guide explains the big moves in simple terms, using law firm and press summaries. It is general information, not legal advice. Companies that ship quantum items should read the actual regulations.

September 2024: the interim final rule

According to The Quantum Insider and several law firm summaries, BIS published an interim final rule around September 5 to 6, 2024. It put worldwide export controls on:

• Quantum computers, along with related equipment, components, materials, software and technology used to develop or maintain them.
• Advanced semiconductor manufacturing equipment.
• Certain additive manufacturing equipment for metals.
• Technology for gate-all-around transistor chips (GAAFET).

One law firm summary reported that the quantum computer controls applied to systems with 34 or more physical qubits depending on error rate. Another report did not give thresholds, so we will not state exact error rate rules here. Check the Federal Register text (BIS docket BIS-2024-0020) for them. The same summaries said the rule also covered cryogenic cooling equipment and certain quantum components such as low temperature chips and parametric amplifiers. Our guide to how quantum computers are cooled explains why those fridges matter.

Licensing and the allies path

Reported licensing features included a worldwide license requirement for the newly controlled items, a presumption of approval for exports to a group of close partner countries, and a presumption of denial for destinations such as China and Russia. The rule also created License Exception IEC (Implemented Export Controls). The idea: if a country adopts equivalent controls, exporters to that country can often skip the license application. BIS reportedly published a table of eligible countries. The article we read noted that several like-minded countries had already announced or implemented similar quantum and semiconductor controls.

There were also two practical provisions for science and business: a 60 day delayed compliance date for quantum items to certain destinations so companies could prepare, and treatment of "deemed exports," which means sharing controlled technology with a foreign national inside the US. A reported grandfathering clause protected foreign national employees who already had access and stayed employed as of September 6, 2024, and BIS asked for public comment on deemed export policy for quantum items. Comments were due around November 5, 2024. We did not look for later changes to the rule, so check current status.

Entity List actions

Separately, BIS can put specific organizations on the Entity List, which generally requires a license for any item subject to US export rules. In November 2021 BIS reportedly added 27 entities, including eight in China such as QuantumCTek, over concerns about quantum computing efforts supporting military applications. On March 28, 2025, a Federal Register notice added a group of entities, and trade press reported seven China based firms were added for acquiring or trying to acquire US items to advance China's quantum capabilities, with license applications reviewed under a presumption of denial. We did not find a 2026 Entity List action aimed at Chinese quantum companies, which is not proof that none happened.

Who feels these rules

University labs, startups and big manufacturers all need compliance staff. A startup selling a cryostat or control electronics abroad may need to ask if its product is covered. Researchers working with international students and colleagues care about deemed exports. And governments care because supply chains for dilution refrigerators and special chips are narrow, a point also raised in our global race overview.

The optimistic read

Controls are a sign that quantum is taken seriously. They also encourage allies to coordinate rules, which can make a trusted market inside which companies and researchers move freely. The Commerce funding described in our CHIPS awards guide and the build-at-home focus in the 2026 executive orders push the same direction: strengthen a secure supply chain at home and with partners.

The honest tradeoffs

• Controls can slow collaboration and add cost for small firms.
• Rules can change, and summaries go out of date.
• Export rules for hardware do not stop the publication of math and algorithms, and they have no bearing on a memecoin. QNT is independent of Quantinuum Ltd and any government. This is not financial advice.
