Silent Waves Selected for the 2025 French Tech 2030 Program
Technology that Enables Discovery
“Being chosen for French Tech 2030 is a strong recognition of the impact and potential of our work,” said Luca Planat, CEO and Co-Founder of Silent Waves. “We're proud to represent the excellence of French research and engineering in quantum hardware, and to be building technology that directly contributes to global quantum progress.”
Silent Waves develops Josephson Traveling-Wave Parametric Amplifiers (JTWPAs) designed to deliver ultra-low noise, wide-bandwidth performance for superconducting quantum computers and cryogenic instrumentation.
Each amplifier is individually characterized at cryogenic temperatures, providing verified performance for gain, bandwidth, noise temperature, and compression point.
This precision engineering ensures researchers and system integrators receive devices that perform exactly as specified, helping accelerate time-to-experiment and reduce calibration uncertainty.
A Superconducting Qubit Physicist at the National Quantum Computing Center (UK) recently commented:
“We tested the Argo JTWPA from Silent Waves in our system, measuring the same performance specified in the datasheet in terms of gain, bandwidth, added noise and compression point. We have been reliably using the amplifier for almost a year to read out different qubit chips, always finding substantial improvement in the SNR of the system, which enables faster and higher-fidelity readout.”
Such testimonials demonstrate how reliable, low-noise amplification is becoming a cornerstone of quantum system performance — not only improving signal-to-noise ratio but enabling new modes of research that demand stability and precision.
Supporting the Next Generation of Quantum Experiments
The recent Alice & Bob paper arXiv:2502.07892 on squeezed cat qubits reported a 160× improvement in bit-flip times, a major step forward in qubit design and stabilization.
While the breakthrough stemmed from the team's innovative architecture and control methods, the experiment relied on a Silent Waves Argo TWPA in the readout chain, confirming the amplifier's reliability and suitability for state-of-the-art superconducting and cat-qubit research.
These examples, from the UK's National Quantum Computing Center to France's Alice & Bob, illustrate how Silent Waves technology is embedded in the front lines of quantum innovation, providing the readout fidelity needed to transform fundamental research into scalable quantum systems.
A Year of Acceleration Ahead
As part of the French Tech 2030 program, Silent Waves will benefit from personalized national support across financing, industrial partnerships, and international growth.
The company will participate in a series of high-level events through late 2025, including La Rencontre de la French Tech at Bercy, the French Tech 2030 Kick-Off, and flagship industry collaborations such as Orange Open Tech and Adopt AI.
“Our mission has always been to make quantum systems more capable, reliable, and accessible,” added Planat. “With French Tech 2030's support, we'll continue scaling our amplifier platforms — Argo, Carthago, and Dreadnought — to serve the world's most advanced quantum research programs.”
