Scalable Qubit Readout to Resolve Superconducting Quantum Computing’s Skeleton in the Closet

Objective

The field of quantum computing faces a critical bottleneck as quantum processors scale beyond 100 qubits: the challenge of high-fidelity qubit readout described as superconducting quantum computing's “skeleton in the closet”. Present readout technologies struggle with noise, bandwidth limitations, and complex cryogenic setups, hindering the path to practical quantum computers. Silent Waves addresses this challenge through a breakthrough technology developed within the TruePA project. Our Traveling Wave Parametric Amplifier and Isolator (TWPAI) offers a revolutionary solution, combining quantum-limited amplification and built-in isolation in a single, compact device. Our TWPAI is a significant leap beyond current state-of-the-art, achieving 20 dB gain and 30 dB isolation with noise performance approaching the standard quantum limit. Importantly, by integrating amplification and isolation functions, we eliminate the need for bulky, magnetically-active individual components, paving the way for scalable quantum processors with thousands of qubits. This project uses well-defined plans to advance our TWPAI to TRL6, focusing on performance optimization, on-chip integration, and system-level validation with commercial quantum processors, showcasing our product to potential customers & key industry players. Our innovation promises to accelerate Europe's quantum computing capabilities, supporting the EU's goal of achieving quantum advantage by 2030. EIC support will accelerate the translation of our cutting-edge research towards a commercial qubit readout product critical to European leadership in quantum technologies, ensuring strategic autonomy in this strategically important field and helping unlock the many transformative applications of quantum computing.
