Researchers Use Quantum Computer to Improve AI Predictions


AI models have been helping with predictions for a while now. Doctors, weather forecasters and stock brokers all use AI to try to peek into the future. Inside the Leibniz Supercomputing Centre in Germany, researchers have been experimenting with an AI model and a quantum computer. The quantum computer helps the AI with complex predictions it can’t handle alone.

The research team from University College London, who published their findings on Friday in the journal Science Advances, say that one day, quantum computers could help AI models make fast, accurate predictions across a range of industries, which would take regular computers weeks to figure out.

“The paper demonstrates that for these kinds of studies, even today’s relatively small and unreliable quantum devices can enhance the predictions of conventional AI models,” Peter Coveney, UCL professor and the study’s coauthor, told CNET. 

Quantum computers differ from regular computers in several ways, including being able to perform simultaneous calculations rather than step-by-step calculations, and using quantum bits. While classical computers use bits as the smallest data unit, with each representing either a zero or a one, qubits can represent both zero and one simultaneously (superposition). Two qubits can also be linked together (entanglement). 

Superposition and entanglement allow quantum computers to solve complex problems much faster than traditional computers. But quantum computers are incredibly delicate and must be kept at extremely low temperatures, making them impractical for everyday use.

But while today’s quantum computers are still experimental and often finicky, they might help AI solve big problems that would otherwise be too complicated or time-consuming. 

Quantum advantage

The AI model used in the study is housed on a supercomputer connected to the quantum computer at the research center.

The team used this setup to predict how gases and liquids in a system would move and interact over an extended period. Climate science, medicine and city engineering all use this kind of modeling.

“Our new method appears to demonstrate ‘quantum advantage’ in a practical way — that is, the quantum computer outperforms what is possible through classical computing alone,” coauthor Maida Wang, a PHD student at UCL, said in an announcement.

Quantum computers are incredibly sensitive. Even tiny disturbances in the environment throw off the calculations, so the technology is still mostly used in research labs. 

Because quantum computing is still limited, the researchers did most of the study with the supercomputer. The AI model handled the data processing, then used the quantum computer for one step.

After completing the hard calculations, the quantum computer handed the reins back to the AI model, so it could take care of everything else. 

“Even today’s noisy and error-prone quantum devices can enhance the performance of conventional machine-learning algorithms trained on data from modern supercomputers,” Coveney said.

Solving big problems

Hooking up an AI model to run calculations on a quantum computer might sound outlandish, but there are already real examples of companies using this approach in healthcare. 

In 2025, Google said its Quantum Echoes algorithm could calculate the structure of molecules that could pave the way for future drug discovery. Also, last year, the University of Toronto and Insilico Medicine used AI with a quantum computer to build molecules that target an “undruggable” form of cancer. 

While there are still challenges with ensuring predictions are reliable, as well as with the sheer size of the datasets involved, Coveney said quantum computers can improve complex predictions. 

“We are already at work on real-world applications,” he said.

In the tax world, excise taxes are often the neglected step-child. They take a back seat to income and estate taxes. They do not make the headlines very often.

Excise taxes are largely transaction-based taxes that target specific industries or activities. The businesses that are subject to these taxes generally just pay them, and consider it a cost of doing business.

But the law and rules for these taxes are often not well developed and they can be very difficult to apply in practice. This can be problematic as a misstep with these taxes can be financially devastating for a business. It often spells the end for the business, or, at a minimum, a need to resolve a significant tax balance with the IRS.

The recent case of Texas Truck Parts & Tire, Inc. v. United States, No. 23-20588.(5th Cir. Oct. 8, 2024) provides an opportunity to consider the ill-defined tire import excise tax. This case resulted in a significant tax liability and expanded definition of who qualifies as an “importer” for this tax–which could be extremely problematic for businesses that import tires for sale in the United States.

Facts & Procedural History

The taxpayer (“Texas Truck”) is a wholesaler and retailer of truck parts and tires based in Houston, Texas.

From 2012 to 2017, Texas Truck purchased tires from Chinese manufacturers, which shipped and delivered the tires to Houston. Texas Truck believed that the Chinese manufacturers were the importers of the tires under applicable law and therefore did not file quarterly excise tax returns or pay any excise tax on the tires.

The IRS audited Texas Truck and determined that it, not the Chinese manufacturers, was the importer of the tires and therefore owed approximately $1.9 million in taxes. Texas Truck paid a portion of these taxes and filed an administrative claim for a refund. After the IRS failed to act on the claim, Texas Truck filed suit seeking a refund.

The district court determined on summary judgment that the Chinese manufacturers imported the tires and were therefore liable for the tax. The Government appealed to the Fifth Circuit, which resulted in the current court opinion.

About Excise Taxes on Imported Tires

Section 4071 imposes tax liability on manufacturers, producers, or importers of taxable tires for their sale. The “or” in the code means that the tax could be imposed on any one of these parties.

This leaves one wondering who qualifies as a manufacturer, producer, or importer? The implementing regulations provide definitions of these terms. As relevant to this case, the regulations define an “importer” as any person who “brings” a taxable article into the United States from a source outside the United States, or who withdraws such an article from a customs-bonded warehouse for sale or use in the United States. These rules are found in Treas. Reg. § 48.0-2(a)(4)(i).

The regulations go on to provide an exception for nominal importers. The regulations say that the beneficial owner, not the nominal importer, is liable for the excise tax. The regulations use the example of a broker who ships an item for the ultimate owner, saying that the owner and not the broker should be liable for the excise tax. As we’ll see below, it is not easy to square the “brings” rule with this exception for nominal importers.

As a side note, astute readers may note that the “sale” is what triggers the tax, not the act of importing the tires. They might wonder if this excise tax could be avoided by having an integrated foreign manufacturer-U.S. sales company so there is no “sale.” The statute addresses this. It says that if a manufacturer, producer, or importer delivers tires to its own store or outlet, it is liable for the excise tax in the same manner as if it had been sold when delivered. Thus, for an integrated manufacturer-sales company, the excise tax is essentially triggered on delivery to the United States.

Who “Brings” in the Taxable Item into the United States?

This tax dispute focused on who “brings” the taxable item into the United States as defined in the regulations. This is important as the regulation clearly says that the party who “brings” the taxable item into the United States is liable for the excise tax.

Let’s start with the IRS’s position. The IRS argued that the term “brings” means causing or making something come from abroad. Under this broad definition, any United States business that ordered tires manufactured abroad would be subject to the tax, regardless of who physically transported the tires into the country. This interpretation would cast a wide net.

The district court did not accept this broad definition. It concluded that the Chinese manufacturers were the parties who brought the tires into the United States, as they physically made the delivery. This interpretation aligns with a common-sense understanding of the word “brings”–i.e., the party that physically transports an item from one place to another.

On appeal, the Fifth Circuit agreed with the district court’s narrower interpretation of “brings.” The Chinese manufacturer was the party that brought the tires to the United States. However, the appeals court concluded that the focus should have been on the other language in the regulations regarding “nominal importer” and “beneficial owner” and that these terms basically overrule the language about who “brings” the tires into the United States.

Who is a Nominal Importer vs. Beneficial Owner?

Okay, so if we ignore who “brings” the tires to the United States, who is a “nominal importer” and who is a “beneficial owner?” These are concepts that are often used with trusts, and even foreign FBAR reporting obligations. The regulations provide a starting point.

A “nominal importer” is an entity that appears to be the importer on paper or in form, but doesn’t have the substantive benefits or risks associated with importing. In this case, the Chinese manufacturers were considered nominal importers because they merely handled the logistics of shipping the tires to the United States on Texas Truck’s behalf.

The “beneficial owner,” on the other hand, is the entity that derives the real economic benefit from the importation. The Fifth Circuit, drawing on previous case law and IRS rulings, defined the beneficial owner as the party who is “the inducing and efficient cause of the importation.”

In applying these concepts, the appeals court considered several factors:

  1. Who initiated the order: Texas Truck placed specific orders with the Chinese manufacturers.
  2. Who benefited from the importation: Texas Truck received the tires for resale in the U.S. market.
  3. The nature of the transaction: The Chinese manufacturers didn’t import tires speculatively to sell in the U.S.; they shipped tires in response to Texas Truck’s orders.
  4. The intent of the parties: The arrangement was set up for Texas Truck to receive tires for its business, not for the Chinese manufacturers to establish a U.S. presence.

The Fifth Circuit concluded that Texas Truck was the beneficial owner of the tires. Even though Texas Truck didn’t physically bring the tires into the country, it was “the inducing and efficient cause” of their importation. The Chinese manufacturers, while technically bringing the tires into the U.S., were merely acting as agents facilitating the transaction.

The Takeaway

Businesses importing tires for sale in the United States, particularly those in Texas and other states within the Fifth Circuit’s jurisdiction, should carefully review their importing practices in light of this decision. They may need to reassess their potential excise tax liabilities and ensure they are properly reporting and paying any applicable taxes. Factors such as who initiates the order, who benefits from the importation, and how the sales process is structured can all impact the determination of who is the “importer” for tax purposes. This interpretation may result in taxpayers needing to restructure their business or having to consider filing excise tax returns for the first time or amended returns to seek refunds.
