Quantum Computing News: IBM, IonQ, and Xanadu Signal the Next Phase of Quantum Infrastructure and Security

Welcome to Thursday’s update on quantum news. In early 2026, the field still shows steady tech work, but the news also shows how firms now focus on safe data, local gear, and state-backed build plans. This round looks at new post-quantum code work with chat apps, a new system set up in Finland, a U.S. state-backed study on quantum safety, and a large chip-and-light tech plan in Canada.

1. IBM Works with Signal and Threema on Post Quantum Code

We begin with International Business Machines IBM -0.29% ▼ , which stated its research team is now working with the chat apps Signal and Threema to test code that can stand up to a future quantum hack risk. The goal is to stop a threat known as “harvest now, decrypt later,” in which bad actors store encrypted data now and try to break it once large-scale quantum gear is ready. The teams aim to shift from old curve-based code to new post-quantum rules set by the National Institute of Standards and Technology in 2024.

For Signal, the group works on a fix for chat group data that may leak key user facts. IBM said that a simple swap to new code could raise data use by about 100x, so it built a new gatekeeper model to keep checks fast and safe. In turn, Threema is adding a key tool known as ML KEM to keep chat links safe while still being quick to run.

2. IQM Adds Fourth Quantum System in Finland

Next, IQM Quantum Computers said it has set up its fourth on-site quantum system in Finland, a 20-qubit unit at Aalto University. The new gear, known as Aalto Q20, will help train new staff and run tests tied to the next stage of chip work. It will also link to the LUMI supercomputer, so users from across the European Union can run jobs on the gear. IQM Chief Executive Jan Goetz said, “When institutions like Aalto University own their quantum computers, it means their data, their IP, and their expertise stay theirs.” In turn, the move helps Finland grow its quantum workforce, as the state may need about 3,000 new hires in the years ahead.

3. IonQ Studies Zero Trust Security for Quantum Systems

Meanwhile, IonQ IONQ -1.28% ▼ said it is now part of a U.S. state-backed plan that looks at how Zero Trust rules may work for quantum gear. The work takes place with the Applied Research Lab for Intelligence and Security under a plan known as SEQCURE. The group will study how new trust checks may guard data and access across the whole quantum stack, from chips to cloud use. IonQ Chair and Chief Exec Niccolo de Masi said, “As quantum systems transition into the bedrock of national infrastructure, the shift from legacy perimeter security to a Zero Trust Architecture is a strategic imperative.” The work is backed by the U.S. Air Force and may guide how state teams set safe rules for future quantum use.

4. Xanadu Seeks $390 Million for Quantum Chip and Light Tech Plan

Finally, Xanadu Quantum Technologies said it is in talks with the state of Canada and the state of Ontario for up to $390 million in aid for a new plan known as Project OPTIMISM. The goal is to build chip and light tech plants that can help make key parts for large-scale quantum gear. The plan may add new tools for chip pack work, chip tests, and the building of full quantum parts.

Chief Executive Christian Weedbrook said the move “reflects a bold vision for building the advanced manufacturing capabilities required to support the next generation of quantum technologies.” If the deal moves ahead, the work may help boost Canada’s role in chip, light tech, and AI gear supply chains tied to the next wave of quantum data centers.
