Qubic develops Kinetic Inductance Traveling Wave Parametric Amplifiers (KI-TWPAs), ultra-low-noise, wide-bandwidth microwave amplifiers intended for reading out superconducting qubits and compatible with other qubit modalities. Its amplifiers derive nonlinear inductance from the transmission line material rather than Josephson junctions, aiming for a more robust, scalable device that operates near the quantum limit and supports multiplexed qubit readout. Qubic reports heat dissipation for its amplifiers is expected to be cut to under 0.1 mW per amplifier, addressing a key bottleneck in cryogenic quantum systems. The company has sold its devices to Quantum Machines and plans to scale manufacturing to meet demand from quantum computing and defense customers. Qubic is also developing an RF quantum sensing platform leveraging its amplifier technology for applications such as threat detection and covert communications, and intends to grow its team three-fold to achieve these goals.
