Freedom Broker pointed to limitations of IonQ’s new technology

IonQ’s (IONQ) new quantum error decoding system demonstrated high speed in simulations, but its results have not yet been validated on a real quantum computer, Freedom Broker analysts note. This limits the development’s immediate use in commercial systems, despite the company’s shares rising 10.4% after the testing announcement.

What IonQ does

IonQ develops quantum computers, software, cloud services, quantum networks, and solutions in information security and sensing technologies. The company aims to create a full-featured quantum platform that combines computing hardware, software products, and component manufacturing.

Quantum computers use qubits—quantum analogs of classical bits. Such systems are potentially capable of solving certain computational tasks that require too much time or too many resources for traditional computers. However, qubits are sensitive to external influences, so errors remain one of the main obstacles to the technology’s commercial adoption.

Results obtained only in simulation

These results are based on simulation rather than the operation of a real quantum computer, which limits their immediate applicability to commercial systems, Freedom Broker analysts noted.

IonQ announced testing of an end-to-end quantum error decoder operating in real time on a single standard central processing unit, or CPU. The decoder analyzes errors that arise during quantum computations and determines what corrective actions must be taken to preserve the result.

The end-to-end approach means the system covers the entire data-processing pipeline—from receiving error information to generating a decision on how to correct it. Real-time operation is especially important, because correction must be performed fast enough not to delay the quantum computations themselves.

In simulation, IonQ’s technology supported circuits of up to 408 logical qubits. A logical qubit is formed using multiple physical qubits and error-correction mechanisms, which should make computations more resilient.

Additional runtime in the most favorable scenario was 0.02%. This metric reflects the computational delay that the decoder adds to the main operation.

However, the testing was conducted in a software model rather than on an operating quantum computer. Simulation makes it possible to evaluate an algorithm under controlled conditions, but it does not fully show how it will cope with noise, hardware constraints, and other features of a real quantum system. Therefore, the technology still needs to confirm its stated characteristics on a hardware platform.

Revenue increased by 287%

IonQ’s financial results show rapid sales growth alongside continuing large losses. In Q2 2026, the company’s revenue reached a record $80.1 million and increased 287% year over year. The result was 20% above the midpoint of the forecast range previously stated by the company.

About 50% of quarterly revenue came from international markets, approximately 60% from commercial customers, and 25% was provided by clients using multiple IonQ products. These categories may overlap, since a single customer can simultaneously fall into the international, commercial, and multi-product segments.

The company also reported that remaining performance obligations under signed contracts grew 297% year over year. This metric reflects the amount of future revenue IonQ expects to recognize under agreements already signed after fulfilling the relevant obligations.

Loss remains significant

IonQ’s GAAP net loss in Q2 amounted to $1.86 billion, or $5.08 per share. The adjusted loss per share reached $0.33. Adjusted EBITDA loss totaled $120.3 million. It included expenses related to the commercial relationship with SkyWater Technology. Excluding these costs, adjusted EBITDA loss would have been $95.6 million.

Company raised its 2026 guidance

IonQ raised its full-year 2026 revenue outlook to $280–290 million. The company still expects organic sales growth of 100% year over year.

The guidance does not include the possible contribution from the acquired SkyWater. This means the expected sales of the new asset are not yet reflected in IonQ’s stated revenue range.

Management attributes the growth to an increase in quantum computer shipments, use of cloud services, and expansion of international and commercial business. The company is also working on demonstrating a 256-qubit quantum computer and plans to publish results of applying error-correction technology on its own hardware.

SkyWater acquisition expanded the manufacturing platform

In January 2026, IonQ agreed to acquire chipmaker SkyWater Technology (SKYT) for about $1.8 billion. The deal provided for a payment of $35 per share in cash and IonQ stock.

In Q2, the company reported completion of the acquisition. The integration of SkyWater is expected to combine IonQ’s quantum developments with the manufacturing of semiconductor components in the U.S. and form a vertically integrated platform. Previously, IonQ also acquired quantum computing systems developer Oxford Ionics for $1.08 billion.

In October 2025, the company carried out a $2 billion securities offering. It included 16.5 million shares at a price of $93, prepaid warrants to purchase 5,005,400 shares, and seven-year warrants to buy another 43,010,800 securities with an exercise price of $155.
