October 2, 2026, marks the debut of WISeSat. Space on the Nasdaq Capital Market under the ticker symbol “SAIQ,” establishing a newly independent public company focused on securing satellite communications. The listing follows the completion of a business combination with Columbus Acquisition Corp., approved by shareholders on September 30, 2026, and positions WISeSat. Space, a subsidiary of WISeQey Corp., to expand its space infrastructure and use its existing cybersecurity expertise.

“The Nasdaq listing represents an extraordinary milestone for WISeSat.Space and for everyone who has contributed to this journey,” said Carlos Moreira, Chief Executive Officer of SEALSQ, WISeQey and WISeSat. Space, adding that the company aims to combine satellite communications with digital identity and post-quantum technologies.

WISeSat. The Nasdaq listing supports WISeSat.Space’s ambition to expand its space infrastructure while leveraging WISeQey’s expertise in cybersecurity, digital identity and secure semiconductors. The listing establishes WISeSat. Space as an independent, publicly traded entity while remaining a subsidiary of WISeQey Corp., which already trades on both the SIX Swiss Exchange and Nasdaq under the symbol WKEY. This affiliation allows WISeSat. Space to use existing expertise in secure semiconductors, digital identity and post-quantum cryptography.

Space has been actively deploying satellites into orbit since 2024, with a core mission to provide secure communications for a growing network of connected devices. Applications targeted by the company include remote monitoring systems, logistics tracking, defense infrastructure and critical infrastructure management, all reliant on robust and trustworthy satellite connectivity.

The company’s approach centers on integrating hardware-based security, device authentication and post-quantum protection directly into its satellite communications architecture, WISeSat. Space says. Space aims to extend trusted connectivity beyond terrestrial networks. “I want to thank our employees, management team, technology partners, advisors, investors and all those whose dedication has made this achievement possible.

Their commitment has helped turn our vision of bringing cybersecurity to space into a growing business,” said Moreira. He further explained the company’s long-term vision, stating, “As more devices and essential services rely on satellite connectivity, trust and post-quantum security must be built into the infrastructure from the outset.”

Ivy Delaney has been working with neural networks and machine learning since the mid-nineties, back when a couple of hidden layers and a long afternoon of training counted as ambitious. She has watched the field go from academic curiosity to the thing quietly running underneath everything, and she brings that long view to quantum computing. For Quantum Zeitgeist she covers the ground where the two fields meet. That means quantum machine learning and the variational algorithms it leans on, and it also means the less glamorous but more interesting story of classical machine learning already doing real work inside quantum machines, decoding error-correcting codes, calibrating noisy hardware and learning the error models that simulators depend on. She writes about the hardware those algorithms have to run on too, and about the post-quantum cryptography scramble that the same hardware has set off. Her stories typically start with the paper, whether that is peer-reviewed work, conference proceedings or an arXiv preprint, with the source linked so you can hold a claim up against the research it came from. She is unimpressed by benchmarks that will not say what they beat, and by demonstrations that only work in the press release.
