“Crescendo Achieving best-in-industry gain and noise performance over the readout bandwidth, the Crescendo travelling wave parametric amplifier (TWPA) enables the multiplexed readout of many qubits at once. This enormous reduction in the required overhead in terms of wiring complexity, up-chain components and cost per qubit compared to traditional narrow-band JPA-based readout solutions facilitates future-proof scalable qubit readout.”

“Bass-A10K Quantum algorithms Bass-A10K processor enables logical algorithms that can solve the first wave of problems that were previously out of reach for humanity. This scale-up is enabled by the modularly scaling from VIO-1K to VIO-40K, delivering the first 10,000 qubits in a single QPU fitting in a cryostat.”
