Rhonexum has progressed to Session 3 of the Creative Destruction Lab – Next Gen Computing (NGC) 2025 program.

Following successful participation in the initial sessions, the team continues its journey within the program, benefiting from close engagement with experienced mentors and the broader CDL ecosystem. The structured, objective-driven format and high standards of mentorship have played a key role in refining Rhonexum’s technical direction and strategic focus. Rhonexum would like to thank the mentors who have been closely supporting the project, as well as the CDL team for their continued guidance and support.

The company now looks ahead to the next phase of the program.

New collaboration announcement!

YQuantum × Rhonexum
We are excited to announce a strategic partnership between two Swiss deep-tech innovators: YQuantum and Rhonexum!

To realize the full potential of quantum computing, hardware must evolve beyond individual components. It requires a holistic approach to how electronics are integrated and scaled within the cryostat.
We are combining Rhonexum’s expertise in active cryogenic integrated circuits with YQuantum’s growing capabilities in system integration and scalable hardware platforms.

By aligning our distinct but complementary technologies, we are developing the robust, system-level infrastructure needed to support the growing complexity of future quantum processors.

More to come soon!

Very excited to see Vicente Carbon representing Rhonexum participating in the Future of Computing today at iXcampus. Big thanks to HEC Paris, iXcampus, and Elaia for hosting the event, and to CDL-Paris for providing us with this opportunity.

#FutureOfComputing2025 aims to do one thing: connect Europe’s scientific excellence with its entrepreneurial and industrial capacity. Our goal is to demonstrate how cryogenic electronics can transform hardware as we know it.

Happy to meet you there! Let's embrace cryogenic electronics together.

We were inspired by the talk of Andrea Orzati, CEO of Zurich Instruments, on one of the most pressing challenges in quantum technology: “Control electronics cost per qubit must go down.”

To make large-scale quantum computing viable, the cost per qubit must drop from >10,000 CHF for laboratory setups to <100 CHF through advances in:

• Multiplexing
• Cryo-electronics and ASICs
• Standardization
• Mass manufacturing

These enablers will drive the transition from experimental systems to scalable quantum processors. At Rhonexum, we share this vision. The path toward scalable quantum computing starts with making every qubit affordable.

We had a fantastic time representing Rhonexum at the EPFL Forum Startup Day 2025! It was a great opportunity to connect with curious minds, share our passion for cryogenic electronics, and discuss how we are shaping the future of quantum and low-temperature technologies.

It was inspiring to see so much interest and enthusiasm from students, researchers, and professionals alike. Many thanks to the Forum EPFL team for the impeccable organization and to everyone who stopped by our booth!

Exciting news from the Swiss innovation ecosystem!

We’re proud to share that Hung-Chi Han, Rhonexum’s CTO and co-founder, has been awarded a BRIDGE Proof of Concept fellowship.
The fellowship provides up to CHF 130,000 to help bring innovative projects closer to market.

We truly appreciate the recognition and support from Innosuisse and the Swiss National Science Foundation SNSF, whose joint BRIDGE Funding Programme makes this possible.

We’re thrilled to see Hung-Chi’s work recognized at the national level and look forward to the impact it will bring in advancing cryogenic electronics for quantum technologies.

A big congratulations also to all the other fellows named in this cohort — the future of deep-tech in Switzerland looks bright!

We are thrilled to share that Rhonexum has been awarded a FIT Tech Grant of CHF 100’000.

This support will help us continue developing our platform, enabling designers to develop and verify chips for next-generation technologies such as quantum computing and space exploration.

A big thank you to FIT - Fondation pour l'Innovation et la Technologie for their trust and support, and congratulations to the other awarded startups Hevelion, Kymansis, and IRIS!

In June, I had the pleasure of attending two key events in the Swiss tech ecosystem: the NCCR SPIN: Spin Qubits in Silicon (focusing on spin-based quantum computing) and the SwissChips (dedicated to advanced IC design).

At both events, I had the chance to present how Rhonexum is unlocking the possibilities of cryogenic electronics. We showcased our transistor modeling solution designed for cryogenic operation, helping to bridge the gap between research IC prototypes and scalable system-level design.

• It was exciting to interact with researchers, engineers, professors, and partners who share a vision for the future of quantum and semiconductor technologies.
• Participating in these events paves the way toward Rhonexum’s vision, which is closely aligned with Switzerland’s strategy in deep-tech innovation.
• We’re proud to be contributing to this momentum, building tools that enable faster, colder, and more efficient innovation.

Many thanks to Dominik Zumbühl, Dr. Tobias Denzler, Tristan Meunier, Simone Frasca, Daniel Jetter, Amina SADIK, Cameron Spence, Yang Liu, Hua Wang, Peter Mueller, Qian Liu, Sriskaran Viros, Nur Aiman Fadel.

What a night to remember at the Changemakers & Blaze Startup Accelerator Award Ceremony – Spring 2025! We are honored and grateful to have received two awards:- SW Startup Spark Award – sponsored by Schellenberg Wittmer- Public Vote Award – chosen by the audience. It was a privilege to pitch Rhonexum alongside an incredible group of founders and to share the stage with such bold, innovative teams.

Thank you to:

• Schellenberg Wittmer for believing in our vision and supporting early-stage innovation
• Blaze Acelerator, EPFL Startup, and EPFL Philanthropy for providing a platform that empowers student entrepreneurs to lead change
• The Consulting Society for helping us sharpen our message and channel the full strength of our pitch
• Maurice Gaillard, Jana Obeid, and the entire organizing team for your continuous encouragement
• Everyone in the audience who supported us with your vote, your enthusiasm truly means the world to us.

And a big shoutout to all fellow participants, especially Carebotics and KoatinG, for their inspiring work and positive energy throughout the journey.

This is just the beginning for Rhonexum. Let’s keep pushing technological boundaries.

Rhonexum is thrilled to be part of the upcoming Changemakers x Blaze Startup Accelerator Award Ceremony – Spring 2025 hosted by EPFL Startup!

We're honored to be among an inspiring group of student-led ventures shaping the future of innovation. Join us on May 26 at the Rolex Forum to explore pioneering ideas, connect with visionaries, and celebrate the entrepreneurial spirit driving deep tech forward.

Looking forward to showcasing our progress on cryogenic electronics and ultra-low-temperature transistor models—powered by our mission to enable the next generation of electronics.

We're excited to share that Rhonexum (Quanexum with a slight renaming since then) has been awarded a CHF 30,000 Ignition Grant!

This milestone supports our mission to advance cryogenic electronics through automated measurement systems and transistor models designed for operation down to -270°C—paving the way for breakthroughs in quantum computing, space exploration, and ultra-sensitive measurements.
