As quantum processors move from laboratory-scale demonstrators towards increasingly complex and industrial systems, their cryogenic infrastructure must scale with them.
More qubits, more interconnections, higher thermal loads and increasing integration density are creating new challenges in cooling power, thermal management, RF and DC connectivity, mechanical integration, magnetic environment, automation and maintainability.
At Absolut System, we believe that the QPU (Quantum Processing Unit) and its cryogenic infrastructure must evolve together.
Our ambition is to provide QPU manufacturers with the cryogenic technologies and system engineering capabilities they need to scale their quantum processors towards industrial and Fault-Tolerant Quantum Computing (FTQC).
Our approach is to make cryogenics a commodity-like, easier to operate with high standards in reliability and industrialisation, allowing QPU manufacturers to focus on their core mission: delivering FTQC.
Beyond QPU developers, Absolut System works with research laboratories and quantum hardware companies requiring advanced cryogenic environments to develop, integrate and test their technologies. From component and technology validation to complete QPU Integration Platforms, our cryogenic engineering capabilities can support different stages of quantum technology development.
Quantum technologies operate across very different temperature ranges and impose very different cooling requirements.
Our approach starts with the QPU requirements — not with the cryostat.
Absolut System defines the cryogenic architecture according to the QPU technology, operating temperature, thermal loads, interfaces and scale-up roadmap.
Increasing the number of qubits is not simply a matter of increasing the size of a fridge.
As quantum processors scale, the number of RF lines, DC connections, optical fibres, control electronics and thermal interfaces increases significantly.
This creates additional heat loads at the different temperature stages and requires increasingly complex thermalisation strategies.
At the same time, QPU developers need systems that are easier to operate, integrate and maintain.
The challenge therefore becomes systemic: more qubits → more interconnections → higher thermal loads → greater cooling power → more complex integration → new cryogenic architectures.
Cryogenics must scale at the same pace as the QPU!
Cooling the QPU is only one part of the challenge.
Future quantum systems require an integrated cryogenic environment combining:
This is why Absolut System goes beyond the traditional fridge approach for quantum computing: we develop complete QPU Integration Platforms engineered around the quantum processor and its operating environment.
A cryogenic platform designed for today’s QPU may no longer meet the requirements of its next generation.
Absolut System therefore works with QPU manufacturers and laboratories to understand not only their current requirements, but also the expected evolution of their processor architecture.
Together, we translate the QPU roadmap into a cryogenic roadmap covering successive development platforms, industrialisation and future scale-up.
Our objective is to anticipate tomorrow’s cryogenic requirements before they become a limiting factor.
Absolut System combines more than 15 years of experience in advanced cryogenics with capabilities covering the complete system lifecycle:
Requirements analysis → Modelling → System architecture → Detailed engineering → Manufacturing → Assembly & Integration → Testing & Qualification → Installation → Commissioning → Maintenance & Services
Our teams bring together expertise in cryogenics, thermal engineering, mechanical engineering, vacuum technologies, instrumentation, control and system integration.
This system-level approach enables us to work alongside QPU developers, quantum hardware companies and research teams, from early technology development and validation through to QPU industrialisation and future large-scale quantum infrastructures.
We don’t just design cryostats. We engineer the cryogenic infrastructure around your QPU roadmap. In addition, when the challenge starts at component or technology level, we engineer the cryogenic environment required to develop, integrate and validate it.
Based on this approach, Absolut System is developing QCube®, a new generation of cryogenic platforms dedicated to quantum computing.
QCube® platforms combine cooling technologies, thermal management, QPU integration, connectivity, automation and system engineering within architectures designed around the requirements of each quantum processor.
From millikelvin environments to high-power sub-Kelvin and Kelvin platforms, the QCube® family is designed to address different QPU technologies and different stages of quantum scale-up.
From the first QPU development platform to future large-scale quantum infrastructures.
Quantum scale-up cannot be achieved by developing the QPU and its supporting infrastructure independently.
It requires close cooperation between quantum processor manufacturers, cryogenic technology providers, control electronics specialists and the wider semiconductor and HPC ecosystems.
Absolut System’s ambition is to build long-term partnerships with QPU developers and to develop the cryogenic technologies required for successive generations of quantum computers.
Our cooperation with Quobly on spin-qubit quantum computing illustrates this approach: aligning QPU and cryogenic roadmaps from the first development platform towards industrialisation and future large-scale systems.
