Quantum Technologies Monthly Analysis Bulletin — September 2026

Global Quantum Agenda

September 2026 proved to be a month in which the production chain emerged as a distinct competitive arena in quantum technologies. IonQ, a developer of trapped-ion quantum computers, acquired semiconductor manufacturer SkyWater Technologies, bringing the link between the design and fabrication of its quantum processors in-house. France-based Quobly demonstrated qubit readout and gate operations on a single chip using a 300-millimetre industrial fully depleted silicon-on-insulator (FD-SOI) process. In Poland, Creotech Quantum's eCAUSIS project, which aims to bring its quantum key distribution (QKD) system into commercial production, received a favourable outcome from European Commission evaluation. The company describes a European supply chain for QKD hardware that is scalable from one thousand to ten thousand units per year. All three developments relate more to serial production capability than to laboratory performance.

A similar emphasis has been reflected in legislative efforts. The American Quantum Competitiveness Act, introduced by Representative Nick Langworthy in the United States, aims to support domestic manufacturing and reduce dependence on foreign sources. The EU Quantum Act, which the European Commission is expected to announce by the end of 2026, is framed around the objective of converting scientific knowledge into industrial capacity.

On the error-correction front, measurable results have emerged. Quantinuum reported a logical memory error rate of 4.6×10⁻⁵ on its 98-qubit Helios system using the Helix architecture — a figure representing the information-storage error rate of a logically stabilised processing unit. National strategy documents and initial public offerings that had featured prominently in recent months have given way, in this period, to manufacturing, revenue and field validation. In the domain of post-quantum cryptography (PQC), revenue figures announced by Keyfactor and SEALSQ reflect the commercial counterpart of the policy timeline. In sensing, the trial in which SandboxAQ's AQNav, presented as a quantum navigation system, determined position without relying on GPS on a Northrop Grumman unmanned aerial vehicle illustrates that flight tests have moved ahead of laboratory demonstrations.

News from Türkiye

The Presidency of the Republic of Türkiye Secretariat of Defence Industries (SSB) announced in its weekly bulletin that the Defence Industries Academy has been conducting a study addressing quantum technologies. The study focuses on the role of quantum technologies in advanced manufacturing and supply chains.

Quantum Computing

IonQ presented its vertical integration strategy at Investor Day 2026. The sixth-generation Superion 256 system was introduced, with customer delivery planned for 2027. It was reported that the Electronic Qubit Control (EQC) approach has reduced per-qubit cost by more than a factor of 300 and shortened the production cycle from nine months to two months. These figures are company statements. The company raised its 2026 revenue guidance to 450–460 million dollars.

IBM introduced its 120-qubit Nighthawk r2 processor. It was stated that active dissipative qubit reset enables more than 100,000 circuits to be executed per second, representing a 25-fold speedup over the Heron generation. Quantinuum's Helix architecture was reported to require 3.5 times fewer physical qubits than the surface code. Xanadu published an updated roadmap targeting fault tolerance in 2028–2029, more than 1,000 logical qubits by 2031, and a logical error rate of 10⁻¹⁶. Quobly announced plans to open cloud access to its silicon spin-qubit-based Alloy Pioneer system by the end of 2026.

Quantum Communications

Cisco and KETS Quantum Security have integrated chip-based QKD into IOS XR routers. Key exchange is carried out automatically over existing Ethernet networks via MACsec. Quantum Computing Inc. presented, at ECOC 2026, a single platform combining high-dimensional QKD with hardware-based quantum authentication and quantum zero-knowledge proof components. Delft-originated quantum communications company Q*Bird has rebranded as Falqon Systems. The company has transitioned from component manufacturing to end-to-end network provision based on measurement-device-independent QKD (MDI-QKD) and operates installations in six European countries. GÉANT and the Quantum Internet Alliance launched a joint effort on European quantum network architecture and interoperability protocols through a memorandum of understanding signed on 8 September 2026. SK Telecom and KISTI have combined a digital twin environment for pre-deployment testing of QKD networks with an ETSI-compliant interface.

On the satellite side, Arqit, Es'hailSat and AIEE demonstrated quantum-safe encryption on operational satellite communications infrastructure in Qatar. Sparkle's Quantum Safe Interconnect service and the Hellas Sat infrastructure established a quantum-safe satellite data link between a data centre in Athens and Cyprus.

Quantum Sensing

SandboxAQ and Northrop Grumman tested AQNav, a magnetic anomaly navigation system presented as a quantum navigation system, on the Lumberjack unmanned aerial vehicle. Real-time positioning without GPS or any external signal was reported. Mesa Quantum raised 11.8 million dollars in a round led by Playground Global; the company aims to bring chip-scale atomic clocks and quantum inertial sensors into production. Diffraqtion, originating from MIT and the University of Maryland, raised its total funding to above 10 million dollars through investment from Lockheed Martin Ventures and Presidio Ventures. The company prepares the first field release of its quantum camera for satellite missions and space situational awareness. Creotech Quantum signed a 24-month contract worth 2.33 million euros with the European Space Agency to develop a space-grade superconducting nanowire single-photon detector (SNSPD). Cloq, originating from the University of Oxford, won first place at the Reuben Entrepreneurship Forum with a compact clock design based on a nitrogen atom trapped inside a buckminsterfullerene cage.

NIST researchers measured the X-rays of plutonium, uranium and neptunium with high accuracy using superconducting transition-edge sensors. The work is directed at material tracking in nuclear facilities.

Policy and Strategy in Quantum

The dominant theme of the period is the PQC transition. Intel Federal Technology Director Steve Orrin highlighted 2030–2031 transition targets for institutions and the January 2027 procurement requirement for national security systems; Intel follows a path that integrates PQC at the silicon level. NIST's PQC standards, the National Security Agency's 2027 target, and Executive Orders 14412 and 14413 have accelerated transition efforts not only in federal agencies but also in the private sector. In IonQ's assessment, in the PQC transition the timelines of regulators, adversaries, vendors and corporate executives do not align with one another. The "harvest now, decrypt later" (HNDL) threat renders this misalignment critical. Symmatrics has launched a voluntary commitment programme envisaging the creation of a cryptographic asset inventory and the preparation of a NIST-compliant migration plan.

In India, Finance Minister Nirmala Sitharaman listed quantum among priority infrastructure investments alongside artificial intelligence and semiconductors; no new budget allocation or timeline was announced. Citing a study attributed to Google, the scenario in which a sufficiently powerful quantum computer could break Bitcoin encryption within minutes was also raised. This scenario rests on secondary reporting and is subject to independent verification.

Investment and Companies in Quantum

Fortaegis Technologies closed a 50-million-dollar Series A round led by Serendipity Capital. The company plans to scale a hardware architecture that generates quantum-resistant keys from the physical properties of silicon across the artificial intelligence data centre, defence and telecommunications markets. EigenQ, a developer of quantum-safe security solutions, secured 45 million dollars in convertible note financing ahead of a Nasdaq listing; the merger with Silicon Valley Acquisition Corp. is targeted for completion in the fourth quarter of 2026. Matter Venture Partners closed its second fund at 450 million dollars. ASML, TSMC, Quanta Computer and the Development Bank of Japan are among the fund's strategic limited partners. Quantum eMotion acquires Plurilock Security for approximately 33.8 million Canadian dollars, with the aim of bringing quantum random number generator (QRNG) hardware into Canadian, US and NATO public procurement channels.

Keyfactor, a cryptography management platform, received a strategic investment of more than 1 billion dollars from Summit Partners and plans to acquire Cofide; the company announced that, driven in part by demand for the PQC transition, its annual recurring revenue has exceeded 200 million dollars. SEALSQ grew its revenue by 131 percent in the first half of 2026 to 11.2 million dollars. It was stated that more than 100 million dollars of the company's pipeline, which exceeds 225 million dollars, is tied to PQC projects. QTREX Quantum reported revenue of 1.55 million dollars in the first half. All of these figures are based on company statements.

From among more than 2,100 applications to the Constructor Start programme, 16 finalists have been selected; 300,000 dollars in direct investment will be distributed as part of Demo Day in Bremen. The quantum technology companies Query Machines and Memstera are among the finalists.

Academia and Education in Quantum

A research team in China directly tested Richard Feynman's path integral formulation. The probability amplitudes of more than 1.4 million possible paths were measured using single-photon measurements, achieving 94.9 percent fidelity. The BESIII collaboration achieved approximately three times better precision than the previous measurement of the electric dipole moment of the Lambda hyperon, using entangled Lambda–anti-Lambda pairs obtained from J/ψ decays. A Stanford University team observed phonon — sound quantum — jumps in a mechanical resonator in real time. Radboud and Columbia universities published in the journal Science a method for suppressing collision-induced losses in molecular quantum gases. An atomic clock announced by the Centre for Quantum Technologies in Singapore in Nature is capable of dividing time at the level of one part in a trillion. A team from the University of Buffalo presented the mathematical solution describing the transition of a frustrated quantum magnet — one in which interactions are mutually conflicting — from a slow regime to a highly entangled fast regime.

On the theory and science communication side, Jonathan Halliwell of Imperial College London explained, through the decoherence and histories approach, that the quantum-to-classical transition does not require a conscious observer. Gregory Scholes of Princeton University argued that biological systems operate through classical networks that are mathematically analogous to quantum effects, rather than through genuine quantum effects. The Quantum Insider and Switzerland-based Tesseract Quantum have entered into a content partnership through "The Quantum Kid," a channel that explains quantum science to children.
