Welcome back to This Week in Quantum — your weekly digest of the most important news from the world of quantum computing.
The week of June 15–20 was a strong one for hardware actually showing up where it’s supposed to run: national labs, supercomputing centers, and even a launch pad. Quantinuum put fresh numbers behind its trapped-ion flagship, IQM got its first U.S. system online, and France signed on the dotted line for a cat-qubit machine. Let’s get into it.
Industry News
Quantinuum unveils Helios — 98 trapped ions, all-to-all connectivity, 99.92% two-qubit fidelity
Quantinuum introduced Helios, a 98-qubit trapped-ion quantum computer built on barium-137 ions using the company’s quantum charge-coupled device (QCCD) architecture. All-to-all qubit connectivity is achieved via a rotatable ion storage ring and an X-junction, and the system reports an average two-qubit gate infidelity of 7.9×10⁻⁴ alongside a single-qubit gate infidelity of 2.5×10⁻⁵ — good enough for average two-qubit gate fidelities of 99.92%.
A companion paper from Sandia National Laboratories and Quantinuum, published in Nature, reports high-fidelity results from the 98-qubit system, including random circuit sampling benchmarks that place Helios’s operations beyond classical simulation reach. It’s a rare case this year of a hardware announcement backed the same week by an independent national-lab validation rather than a press release alone.
IQM deploys its first U.S. quantum computer at Oak Ridge National Laboratory
IQM’s 20-qubit Radiance system, named Pathfinder, is now operational at Oak Ridge National Laboratory — home to Frontier, the world’s most powerful open-science supercomputer. It’s ORNL’s first commercially procured quantum computer and IQM’s first system on U.S. soil, and it will be connected to high-performance computing systems within the National Center for Computational Sciences’ Technology Integration Group test bed. ORNL owns and operates the hardware on its own campus, matching IQM’s on-premises deployment model that gives customers direct ownership and control of both the system and its underlying IP. IQM has now sold 23 full-stack quantum systems worldwide.
France taps Alice & Bob to deploy an 18-cat-qubit system at GENCI’s supercomputing center
Following President Macron’s announcement in May on the second phase of France’s National Quantum Strategy, GENCI (Grand Équipement National de Calcul Intensif) and Alice & Bob signed an agreement at VivaTech on June 17 for France’s acquisition of an 18-cat-qubit quantum computer, in the presence of French government representatives. It’s a concrete national procurement rather than a pilot MOU, and it lands the same week Alice & Bob’s Helium platform (unveiled the week prior) starts looking for its first customers.
Amazon’s Peter DeSantis: commercially useful quantum computers are five to seven years out
Speaking to CNBC on June 17, Amazon’s top infrastructure executive, Peter DeSantis, forecast that the first commercially useful, small-scale quantum computers will arrive within five to seven years. He pointed to Amazon’s own error-correction progress with its Ocelot chip as the inflection point, after which he expects the technology to scale rapidly — drawing a comparison to Moore’s Law. The estimate places Amazon roughly mid-pack among the industry’s public timelines, more cautious than some 2028–2029 claims and more bullish than the most conservative skeptics.
Quobly closes €115 million Series A to industrialize silicon-based quantum computing
French startup Quobly announced the close of a €115 million Series A round to accelerate the industrialization of its silicon-based quantum computers, with a first commercial product — codenamed “Alloy” — targeted for cloud delivery by the end of 2026. The bet is that leaning on existing semiconductor manufacturing infrastructure gives silicon qubits a shorter path to volume production than more exotic modalities, though the 2026 commercialization timeline is an aggressive one to hold.
INNOSPACE and Norma sign MOU to demonstrate quantum hardware in orbit
South Korean launch provider INNOSPACE and quantum computing firm Norma signed a memorandum of understanding to test Norma’s compact quantum processing unit payload aboard INNOSPACE’s HANBIT rocket, with the goal of gathering operational data under real space conditions. The partnership frames this as a first step toward a cloud-linked Space Quantum Computing Center supporting quantum-enhanced satellite operations — a niche but concrete bet on getting flight data rather than just lab claims.
Atom Computing and Nu Quantum partner on utility-scale, photonically networked quantum computers
Atom Computing and Nu Quantum formalized a partnership, via a memorandum of understanding, to combine Atom Computing’s neutral-atom processors with Nu Quantum’s photonic networking hardware, targeting fault-tolerant, distributed quantum architectures. The collaboration covers integrated photonic network switches and qubit-photon entanglement — the kind of interconnect work that becomes necessary once a single chip can no longer hold enough qubits on its own. Nu Quantum’s earlier $60 million Series A for photonics adds some financial backing to the engineering ambition.
IonQ launches Clavis XG Multiplex for metro-scale quantum key distribution
IonQ introduced Clavis XG Multiplex, the newest addition to its Clavis XG quantum key distribution portfolio, designed to run quantum and classical data simultaneously over existing metropolitan fiber networks without requiring infrastructure redesign. The pitch is straightforward: removing the need to lay new fiber is what turns QKD from a science project into something an enterprise security team can actually budget for.
QuEra announces Libra, a fault-tolerant quantum computer targeted for 2028, and expands its AWS partnership
QuEra Computing unveiled Libra, its first fault-tolerant quantum computer, aiming for over 256 error-corrected logical qubits, roughly one million reliable logical quantum operations, and a logical error rate of 10⁻⁶. The system is planned for delivery via Amazon Braket in 2028 as part of an expanded multi-year collaboration with AWS. As with most 2028-dated roadmaps in this sector, the numbers are encouraging on paper — the real test is whether the hardware shows up on schedule.
Research Highlights
MIT and University of Ferrara develop a mathematical framework for distinguishable quantum light states
Researchers from MIT and the University of Ferrara published a new mathematical framework in Physical Review A that translates quantum states of light into algebraic varieties, enabling more precise design and differentiation of non-Gaussian quantum states via photon addition and subtraction — operations already routine in today’s labs. Better distinguishability between quantum states underpins practical applications in sensing, communications, and computation, moving the theory closer to lab-bench reality.
Passive quantum error correction reaches the qubit-lifetime break-even point
Researchers led by Shruti Shirol at the University of Massachusetts Amherst designed a passive quantum error correction technique that lets qubits correct their own errors, published in Physical Review X. The protocol turns the energy dissipation that normally degrades a qubit into a stabilizing mechanism instead, doubling qubit lifetime and reaching a genuine break-even point — a promising route toward hardware that needs less active error-correction overhead outside carefully controlled lab conditions.
Duke University automates variational quantum eigensolver experiments on trapped-ion hardware
A Duke University team built an automation framework for running variational quantum eigensolver (VQE) chemistry experiments on trapped-ion hardware, executing over 60,000 circuits across multiple molecular test cases with minimal human intervention. The framework cut runtime by 60% and recovered 71% of correlation energy compared to pre-quantum classical baselines — a meaningful workflow upgrade for academic labs, even though the underlying hardware remains the bottleneck on accuracy.
Origin Wukong crosses one million computing tasks and rolls out a post-quantum cryptography shield
China’s Origin Wukong superconducting quantum computer, developed by OriginQC, has been operational for over two years and has now completed more than one million computing tasks, serving users from over 192 countries. Alongside the compute milestone, the Anhui Provincial Key Laboratory of Quantum Computing Chips confirmed the system now integrates Origin Rock, China’s post-quantum cryptography framework designed to withstand both quantum and classical attacks — pairing a compute workhorse with its own security stack rather than treating PQC as an afterthought.
