While that noise hasn't completely disappeared, Quantum World Congress 2026 proved that the market's tolerance for hype is rapidly wearing thin.
Demonstrating real-time decoding in a simulation is not the same as demonstrating real-time quantum error correction on real hardware.
While earlier benchmarks like Quantum Volume were helpful for NISQ-era systems, they don’t keep pace as fault-tolerant systems scale beyond classical simulation limits.
The companies that win the next phase of quantum computing will not simply invent breakthrough technologies.

SHI has urged organisations to prepare for the security risks posed by quantum computing, warning that companies need greater crypto-agility across their technology systems.
Brad Bowers, Lead Field CISO Global at SHI, said businesses could face a narrow window to replace vulnerable cryptographic systems if quantum computing advances at the faster end of current forecasts.
Replacing cryptographic systems across large organisations can take years because encryption is embedded in applications, networks, databases, identity systems, connected devices and business processes.
One of those risks is known as harvest now, decrypt later, in which attackers collect encrypted data today in the expectation that future quantum systems may be able to unlock it.
Some observers have interpreted findings like this as evidence that post-quantum cryptography remains immature.

Insider Brief Researchers operated a programmable quantum photonic processor in orbit, demonstrating two-photon interference as an early step toward onboard quantum computing.
The processor manipulated two photons in a six-path optical circuit, but detector failures, radiation damage and sunlight-related noise constrained its performance.
Researchers programmed different circuit settings and observed two-photon quantum interference, a behavior needed for several approaches to photonic quantum computing.
This project combined a programmable optical circuit with interference between photons, bringing together two elements needed to process quantum information aboard a spacecraft.
There are potential commercial applications — or, at least, practical applications — for an eventual space-based quantum computing systems.

French quantum computing company Quandela is pushing forward with quantum chip manufacturing that leverages South Korea's semiconductor ecosystem.
The vision is to leverage South Korea's semiconductor process and packaging capabilities in the quantum chip manufacturing process.
The company is also working with Yonsei University, the Korea Research Institute of Bioscience and Biotechnology, and the Korea Research Institute of Standards and Science.
If quantum chip manufacturing collaboration with South Korean semiconductor companies materializes, South Korea could expand its role in the quantum computing hardware supply chain, following its positions in AI memory and foundry services.
As Quandela considers South Korea as one of its potential production bases outside Europe, attention is focused on how quickly its engagement with the South Korean semiconductor ecosystem will expand.

September 28, 2026 • 2 min read Samsung is researching a new way to arrange memory in future quantum computers.
The company has patented a structure that stacks superconducting quantum memory in layers rather than placing the components side by side.
A vertical memory structure for quantum computers Samsung has registered a patent in South Korea under KR102778201B1 for a new superconducting qubit memory structure (via ETNews).
The patent focuses on stacking multiple superconducting resonator layers vertically, so quantum memory components can occupy more of the same chip area.
Quantum computers operate differently from conventional computers.

For the first time, a quantum processor has operated in space.
Heat, vibration, electromagnetic interference, and other disturbances can disrupt those states, introducing errors or destroying the quantum behavior the computer needs to work.
The processor developed by Walther and his colleagues uses particles of light – photons – to carry quantum information.
For the processor to exploit their quantum behavior, those photons need to be indistinguishable from one another.
The only way to tackle these problems was going to be one piece at a time – with the rocket launch first on the menu.

Quantum Computing (QUBT) Quantum Computing Inc. leans into the quantum hardware theme through its Entropy Quantum Computer and photonic quantum products, while still earning about US$9.8 million from software and programming and carrying a market value around US$2.0b.
Quantum Computing Inc. gives this screener a pure-play feel on photonic quantum hardware, since the business is building room temperature machines and related chips that aim to plug directly into AI and data center workloads.
"Acceleration of AI and data center workloads is driving urgent demand for energy efficient, high speed computing.
This is positioning QCi's room temperature photonic quantum and reservoir computing platforms to scale from small research contracts to larger production deployments, which should expand revenue and support higher gross margins as volumes increase."
Read the full narrative for Quantum Computing to see how Quantum Computing's photonic edge could turn that pressure into accelerating upside potential.
