Qubic Sells Cryogenic Amplifiers to Quantum Machines

Qubic has secured its first customer contract for its low-noise cryogenic amplifiers, marking a commercialization milestone for the company’s quantum hardware technology. The customer is Quantum Machines, a provider of hybrid control systems for quantum computing. Under the agreement, Quantum Machines will receive early access to Qubic’s cryogenic amplifier technology as an integration partner and will evaluate the devices within its broader quantum computing technology stack.

The collaboration reflects a growing industry focus on more tightly integrated quantum-classical systems, where component-level improvements can directly affect system-level performance. In quantum computers, low-noise signal amplification is especially important for qubit readout, where extremely weak signals must be measured accurately and quickly inside cryogenic environments.

“Anyone following the quantum computing space is aware that the industry is evolving very quickly. Innovative companies like Qubic are contributing to that evolution by developing the components required to overcome the primary roadblocks slowing the scalability of quantum computers. This initial purchase by Quantum Machines represents a confirmation that the amplifiers we’ve developed can and do address a key barrier to the scalability of quantum computers,” said Jerome Bourassa, CEO and Co-Founder at Qubic.

Qubic is also working with the Israeli Quantum Computing Center, a testing platform for quantum components and operational quantum systems. Through that collaboration, Qubic plans to test and evaluate its amplifiers in real quantum computing environments, helping quantify performance gains and validate the devices for future quantum computing use cases.

The primary expected benefits include reduced heat dissipation at 4 Kelvin, faster setup, improved reliability, improved qubit readout, and a simplified user experience. These capabilities are particularly relevant for high-fidelity, low-latency readout, which is needed for real-time quantum control.

The contract calls for Qubic to deliver three versions of its KI-TWPA amplifier by the end of the year. Each version is expected to build on the performance of the previous device. The amplifiers are designed to operate at frequencies matching current readout norms while delivering strong gain and heat dissipation of under 0.1 milliwatts.

“We have been following Qubic’s progress in developing amplifiers optimized for cryogenic conditions. The results are encouraging so far and we’re happy to start testing how such components can be integrated into the cryogenic environment of different quantum computing systems. More broadly, we see this as part of the industry’s shift toward more tightly integrated quantum-classical architectures, where advances across the full control and readout stack are essential for enabling scalable, low-latency quantum systems and delivering greater value to our customers,” said Itamar Sivan, CEO of Quantum Machines.

KI-TWPAs, or kinetic inductance traveling-wave parametric amplifiers, are ultra-low-noise, wide-bandwidth devices that boost microwave signal amplitudes with minimal distortion. They are designed for reading out superconducting qubits and may also be applicable across other qubit modalities.

Qubic’s approach sources nonlinear inductance from the transmission line material rather than relying on Josephson junctions. According to the company, this design eliminates a component that can introduce reliability challenges in some amplifier architectures. The device is also designed to operate near the quantum limit and support multiplexed qubit readout.

“We are excited to collaborate with Qubic in testing these next-generation amplifiers within IQCC’s infrastructure,” said Nir Alfasi, General Manager of the Israeli Quantum Computing Center (IQCC). “Evaluating such technologies in real experimental systems is key to understanding their impact on readout performance, noise, and scalability.”

Thermal management remains one of the major technical constraints in scaling quantum computers. Qubic said its amplifiers dissipate dramatically less heat at 4 Kelvin than alternative technologies, which can account for a substantial share of the heat load in cryogenic readout environments. Reducing that heat load can lower cooling demand and support efforts to increase the number of qubits in a quantum system.

As quantum computer manufacturers work toward larger and more capable systems, cryogenic infrastructure, readout electronics, and quantum-classical integration are becoming increasingly important. Qubic’s amplifier technology is intended to address one of those bottlenecks by reducing heat dissipation while supporting high-quality microwave signal amplification.

The agreement with Quantum Machines represents an important step in the commercialization of Qubic’s KI-TWPA technology. In parallel, testing with IQCC will allow the devices to be evaluated in operational quantum systems. Together, the collaborations position the amplifiers for validation within advanced quantum control architectures and future deployment in scalable quantum computing environments.
