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.

الخلفية

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. Sunlight is far messier than laser light, and the group found that did not stop the pairs from forming.

  • Micius satellite (China) Sent linked light pairs between ground stations 1,200 km apart in 2017 using a laser it carried.
  • Xiamen University team Used sunlight for a related imaging result in April 2026 without showing the pairs were truly linked.

Canada is putting $20.3 million into a quantum research hub for its military

The Quantum Insider

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.

الخلفية

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.

الخلفية

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.

الخلفية

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.

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.

الخلفية

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.

الخلفية

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.

IBM uses AI to discover 465 new ways to protect quantum computers from errors

IBM Research

IBM pointed an AI-guided search at the design space of error-correcting codes. One of the finds packs 50 protected qubits into a design where the previous best of that size held 16, but the candidates still need verification and testing on real hardware.

Quantum Art spun out of Roee Ozeri's group at the Weizmann Institute and is led by CEO Tal David and CTO Amit Ben Kish. It raised a $100 million Series A in December 2025 and extended it to $140 million, bringing total funding to about $200 million. Its architecture centers on multi-qubit gates and optical segmentation of ion chains into cores.

Rigetti's newest 108-qubit computer is now available to rent through Amazon's cloud

Quantum Zeitgeist

The machine, called Cepheus-1, is built from twelve small chips tiled together rather than one large one, and it triples the qubit count of Rigetti's previous generation. It runs on Rigetti's own cloud as well as Amazon Braket.

الخلفية

Rigetti was founded in 2013 by Chad Rigetti. Its 84-qubit Ankaa-3 system reached 99.5% median two-qubit gate fidelity in December 2024. The 36-qubit Cepheus-1-36Q, built from four 9-qubit chiplets, followed in 2025 as the company's first multi-chip system at that fidelity level.

Conductor Quantum lets AI coding assistants run real quantum computers from your editor

Conductor Quantum

The new tool, called CODA MCP, connects assistants like Claude to more than 1,000 qubits of hardware from IBM, IonQ, Rigetti, and Quantinuum. No account setup is needed to start running jobs.

الخلفية

Conductor Quantum was founded in 2024 by Brandon Severin and Joel Pendleton, who met during PhDs at Oxford. The Y Combinator-backed startup has raised about $4 million and builds AI software that automates tuning of silicon spin qubits. It partnered with Finnish silicon-qubit maker SemiQon in November 2025.

Quantinuum turns 98 raw qubits into 48 reliable ones, a ratio thought to be years away

Quantinuum blog

Quantum computers fight errors by bundling many raw qubits into one dependable one. A year ago, the common estimate was that each dependable qubit would need hundreds or thousands of raw ones. Quantinuum did it with about two.

الخلفية

Quantinuum was formed in 2021 by merging Honeywell Quantum Solutions and Cambridge Quantum. It launched Helios in November 2025 with 98 barium-ion qubits and about 99.92% two-qubit gate fidelity, succeeding the 56-qubit H2. Honeywell raised $600 million for the company in September 2025 at a $10 billion pre-money valuation.
