Company profile
KELVIN QUANTUM LTD develops the electronics layer for quantum technology, including readout and control systems engineered to operate at the same ultra-low temperatures as the quantum processors and sensors they serve. Its Cryo-CMOS hardware is designed for continuous operation from room temperature down to deep cryogenic conditions, addressing a bottleneck that the company associates with scaling quantum systems. The company designs from the chip up, with expertise spanning mixed-signal and analogue RF ASICs, cryogenic-capable DACs, ADCs, mixers and amplifiers, in-fridge FPGA platforms, electronic sub-systems and complete packaged solutions. Based in Glasgow, Scotland, KELVIN QUANTUM LTD specializes in electronic verification using in-house cooling systems that operate down to millikelvin temperatures, allowing designs to be characterized and validated under the conditions they are expected to face in use. By integrating electronics directly inside cryogenic refrigeration systems, the company states that it can improve connectivity, reduce power consumption and noise, enable faster and more precise measurements and simplify system architecture for larger-scale quantum machines. KELVIN QUANTUM LTD also develops in-cryostat electronic systems for control and readout of quantum technologies using RF and DC signals, linking Cryo-ASICs and Cryo-FPGA systems to complete low-temperature control architectures. Company milestones listed with its technology information include graduation from ChipStartUK and winning the best start-up pitch at Q2B 2025.
Exhibits
Cryo-ASICs are presented as low-power integrated-circuit solutions built on Kelvin Quantum's experience in cryogenic circuit design. The company designs analogue and mixed-signal ASICs using CMOS process nodes, tailoring, characterizing and validating them for operation down to mK temperatures and targeting ultra-low power dissipation where every milliwatt of heat load matters. Kelvin Quantum deliberately uses commercially available CMOS foundry processes rather than exotic technologies, citing supply-chain stability, multi-source availability and a well-understood reliability track record for long-lived quantum-computing deployments. For cryogenic packaging, it selects and validates packaging materials and interfaces for mechanical and thermal performance at cryogenic temperatures, with the goal of robust electrical connections and long operating lifetimes in extreme environments. ASIC customization is based on the customer's qubit platform, control topology and system-level constraints so that the resulting device fits the specific cryostat architecture. The Quantum Control Platform provides full in-cryostat systems for readout and control of on-chip quantum devices using RF and DC signals, supported by FPGA processing power, high-frequency PCBs, peripheral electronics and packaging that can be integrated within commercial cryogenic refrigeration systems. Its listed platform capabilities are RF capability DC-20GHz, a reprogrammable FPGA based system, operation from room temperature to milliKelvin, real time reconfiguration and packaging designed for EMC and optimized for heat transfer. Because refrigerators are bespoke and cooling power varies, Kelvin Quantum offers tailored solutions for the customer's system and application rather than treating the control platform as a fixed configuration. Cryogenic Sub-Systems provide semiconductor-based electronic subsystems for in-cryostat integration of quantum control and readout operations, with the company describing faster, more accurate and higher-density operation and benchmarking at cryogenic temperatures. The Multiplex capability spans DC and RF functions out to hundreds of outputs, supporting high-channel-count cryogenic control architectures. Power Supplies are described as in-cryostat reconfigurable voltage and current supplies for low-temperature systems. Signal generation and manipulation components include Digital to Analogue converters, Analogue to Digital converters, RF synthesisers and Mixers. FPGA-based microcontrollers are offered for bespoke operation, experimentation and characterization at cryogenic temperatures. The company's project process starts with Technical Consultation, where requirements such as qubit count, gate fidelity targets, power budget and operating temperature stage are mapped. It then develops the architecture and schematic, presents design trade-offs before transistor layout, completes a full custom ASIC layout with DRC/LVS clean status and submits it to the foundry. After tape-out, Kelvin Quantum performs cryo bring-up and characterization in its own cryogenic test infrastructure and supports integration of the resulting system into the customer's cryostat.
