The Quantum Insider
Anderon, a new IBM company in Albany, New York, signed a $1 billion CHIPS Act award to make quantum chips in the US. IBM is putting in another $1 billion, and the first chips have already run through the factory.
Historie
IBM and the Commerce Department announced the plan in May 2026 as a $2 billion deal, half from the government and half from IBM. IBM spun Anderon out as a standalone company headquartered in Albany, New York, and calls it America's first factory built only for quantum chips.

A US national lab ranked top quantum computers on one test, and Quantinuum's leads Google and IBM by about 7x
Quantum Computing Report
Sandia National Laboratories, with Quantinuum and Nvidia, released a test that runs the same random programs on any quantum computer and reports the largest program it still gets right. Quantinuum's Helios scored about seven times higher than Google's Willow or IBM's best machine. Quantinuum helped design the test.
Historie
Sandia has benchmarked quantum hardware for the US government for years and in June 2026 published an independent check of Helios in Nature that confirmed Quantinuum's accuracy claims. Helios launched in November 2025 with 98 qubits, and in September 2026 Quantinuum reported a new error-correction scheme running on it. Quantinuum raised $600 million at a $10 billion valuation in September 2025.

Sunlight can make the linked pairs of light that quantum devices need, with no laser involved
Optica
A team from the University of Ottawa and the Max Planck Institute for the Science of Light focused sunlight onto a crystal and got pairs of light particles linked in the way quantum encryption and sensing depend on. The pairs were nearly as good as the ones lasers produce.
Historie
Producing linked pairs of light this way has relied on lasers since the 1980s. The work was published in the journal Optica on August 6, 2026 by a group spanning Ottawa and the Max Planck Institute for the Science of Light in Germany. A separate team at Xiamen University in China reported sunlight-driven photon pairs for imaging in April 2026.

An Amazon researcher says quantum computers could break the math behind new encryption standards
The Quantum Insider
Daniel Simon of Amazon posted a method for solving the math problem those standards rely on for their security. Other cryptographers have not checked the work yet, and no one has worked out how big a quantum computer would need to be to run it.
Historie
Simon wrote the 1994 paper that first showed a quantum computer could solve a specific task far faster than any ordinary computer. Peter Shor credited it as the direct inspiration for his own 1994 method for breaking the encryption used across the internet. Simon now works in the cryptography group at Amazon Web Services. The problem he attacks here has resisted a fast solution since Oded Regev tied it to lattice-based encryption in 2002.

D-Wave built a quantum chip where each qubit reports most of its own errors
D-Wave
In a Nature paper, D-Wave showed a two-qubit operation for a design that catches about 90% of its errors as a calculation runs. Knowing where an error happened means far fewer spare qubits are needed to correct it.
Historie
D-Wave was founded in 1999 in Burnaby, Canada, and sold the first commercial quantum computer in 2011 to Lockheed Martin. Its business has always run on annealing machines, a narrower design aimed at optimization rather than general-purpose computing, and its 4,400-qubit Advantage2 shipped in 2025. Its 2025 claim of beating supercomputers at a magnetism simulation was challenged by researchers who matched it on four graphics cards. This result comes from a separate general-purpose line the company added to its roadmap.

Caltech and the startup Oratomic cut the qubits needed to fix quantum errors by about 100 times
Quantum Computing Report
Quantum computers need spare qubits to catch their own mistakes. The standard method uses more than 100,000 qubits to protect 195 reliable ones, and the new design does the same job with 975.
Historie
Oratomic came out of stealth on March 31, 2026 and raised a $300 million Series A in July, co-led by ARCH Venture Partners, Spark Capital and Khosla Ventures. It was founded by researchers from Caltech, Harvard and Google, including the Caltech professors Manuel Endres and John Preskill. The company builds its machines from single atoms held in place by laser beams, and says a genuinely useful machine needs only 10,000 to 20,000 of them by 2030. The new result is a preprint posted to arXiv on August 3, 2026.

IBM says its quantum computers beat the best supercomputers on three problems, with checkable answers
Quantum Computing Report
IBM published three results with the University of Chicago, Qedma and Algorithmiq. Its machines ran physics problems that leading supercomputers could not match, and each result came with a way to check the answer that past claims lacked.
Historie
IBM made a similar claim in 2023 with a 127-qubit machine running a magnetism problem. Other researchers reproduced that result on ordinary computers within weeks, some of them on a single laptop core. IBM has said since then that it wants a checkable advantage by the end of 2026. The machines used here run in IBM's own cloud, and the circuits were posted publicly so others can try to match them.

A California lab shrank a quantum computer's control room onto a chip inside the freezer
Quantum Computing Report
HRL Laboratories replaced the racks of room-temperature electronics that normally drive a quantum computer with one control chip sitting next to the qubits inside the cooling system. The machine then found and corrected its own errors without help from outside.
Historie
HRL Laboratories is in Malibu, California, and is jointly owned by Boeing and General Motors. It started as Hughes Research Laboratories, where the first working laser was built in 1960. Its quantum group has spent years on a silicon qubit design that is operated with voltage pulses alone, paid for largely by US defense research money. IBM announced on July 23, 2026 that it plans to buy the lab.

A Swiss startup raises $25.5 million to lay out quantum chips as a grid instead of a single line
The Quantum Insider
ZuriQ, a spinout from ETH Zurich, built a chip that holds nine charged atoms in a 3 by 3 grid. Rival machines line their atoms up in one row, so a grid lets the count grow with the area of the chip rather than its length.
Historie
ZuriQ was spun out of ETH Zurich by Pavel Hrmo, Tobias Saegesser and Shreyans Jain. It raised $4.2 million in a pre-seed round in 2025, bringing the total raised to $29.7 million. The nine-atom demonstrator took about 18 months to build, and the chips are made by Infineon. Quantonation led the new round.

The Quantum Insider
SAXON Q, a spinout of the University of Leipzig, opened orders for two diamond-based machines that need no cryogenic cooling and slide into a standard server rack. The smaller one ships within three months. The larger one arrives in 2027.
Historie
SAXON Q spun out of the University of Leipzig in 2021. It builds qubits from atom-sized flaws in diamond crystals that keep working at room temperature, so the machines skip the heavy cooling most quantum computers need. The company says these are the first diamond machines of this kind to pass 10 qubits, and points to more than 220 patents behind the manufacturing. Early units are going to the German Aerospace Center and a Fraunhofer institute.

Quantinuum shows a long-theorized exotic route to quantum computing actually works
Nature
Working with Harvard, Chicago, and Stony Brook, Quantinuum used 54 qubits to build a complete set of quantum operations from exotic states of matter, a first on real hardware. The approach could cut the overhead of error-resistant computing.
Historie
Quantinuum formed in 2021 from the merger of Honeywell Quantum Solutions and Cambridge Quantum. In 2023 its H2 processor created and braided non-Abelian anyons for the first time, but that earlier work did not produce a universal gate set. Quantinuum's current flagship, the 98-qubit Helios system, was independently validated by Sandia in June 2026 at 99.921 percent two-qubit gate fidelity.

EeroQ shows a way to wire up a million qubits with fewer than fifty control lines
Quantum Computing Report
EeroQ moved packets of electrons across its chip a billion times, covering tens of kilometers in total, without losing a single detectable one. It is a demonstration of moving qubits around, not of computing with them.
Historie
EeroQ was founded in 2017 to build quantum computers from electrons floating on superfluid helium, a platform first proposed in the late 1990s. Its technology was developed in partnership with Michigan State University, and the company raised a $7.25 million seed round led by B Capital's Ascent Fund in August 2022. Its chips are fabricated with standard CMOS processes.

QuEra and Los Alamos find a design that makes useful quantum simulation far cheaper
QuEra
The design needs a few thousand qubits for physics-simulation jobs that standard schemes would need hundreds of thousands for, and runs about 250 times faster. The catch is scope: it covers structured simulation problems, not general-purpose computing.
Historie
QuEra was founded in 2018 out of neutral-atom research at Harvard and MIT. It put Aquila, a 256-qubit analog machine, on Amazon Braket in November 2022. In December 2023 the Harvard-led team behind QuEra demonstrated 48 logical qubits on 280 physical qubits, and in February 2025 the company raised $230 million from investors including Google and SoftBank.

Los Alamos finds that quantum AI models that train well can be run on ordinary computers instead
Los Alamos Reporter
The models were designed to dodge a common failure that stops quantum AI systems from learning. The same design turns out to make them easy to imitate on regular computers, undercutting research that assumed they kept a quantum edge.
Historie
Barren plateaus, where gradients vanish exponentially as qubit counts grow, were identified in variational quantum circuits in 2018. The Los Alamos team led by Marco Cerezo first posted the simulability argument on arXiv in December 2023 and has now published it as a perspective in Nature Communications.
