Periodic Reporting for period 1 - cVIS-QM (cryogenic Vibration Isolation enabling Low Temperature Scanning Probe Microscopy in cryogen-free dilution refrigerators)
Periodo di rendicontazione: 2024-11-01 al 2025-07-31
Quantum technology development in Europe is limited by vibrations in cryogen-free dilution refrigerators, which hinder scanning probe microscopy (SPM) and other ultrasensitive techniques at milli-Kelvin temperatures. While these systems avoid liquid helium dependence and allow large-scale operation, vibrations from pulse tube coolers restrict qubit characterization, slowing quantum computing and sensing progress.
The cVIS-QM project tackled this by commercializing cryogenic vibration isolation (cVIS) from the QuCoM Pathfinder project, focusing on:
Demonstrating vibration isolation inside a dilution refrigerator for high-resolution SPM.
Conducting a market study to assess user needs and opportunities.
Defining a Minimum Viable Product (MVP) for integration into cryostats and labs.
Impact includes enabling nanoscale imaging at milli-Kelvin temperatures, providing retrofit solutions for existing refrigerators, and strengthening Europe’s technological sovereignty in quantum technologies, supporting the Quantum Flagship and Chips Act.

The cVIS-QM project had three work packages: WP1 – Demonstrator, WP2 – Market Study, WP3 – MVP Definition, focusing on validating cryogenic vibration isolation (cVIS) in dry dilution refrigerators, its impact on scanning probe microscopy (SPM), and defining commercialization requirements.
WP1 – Demonstrator: A compact cVIS unit was installed in a cryogen-free dilution refrigerator. Design optimization achieved a first resonance below 0.5 Hz. Integration proved straightforward, and an STM suspended on cVIS achieved sub-nanometer vertical resolution despite pulse tube vibrations, validating stable high-resolution SPM operation at milli-Kelvin temperatures.
WP2 – Market Study: Over 10 in-depth interviews and ~70 conference interactions confirmed vibration isolation as essential for SPM (AFM, STM, SQUID-on-tip) and levitation-based sensing, with retrofit compatibility highly valued.
WP3 – MVP Definition: Insights from WP1 and WP2 defined an MVP for Bluefors LD series cryostats with <0.5 Hz resonance, -100 dB attenuation, passive, non-magnetic, and magnet-compatible design. No competing solutions exist, confirming strong demand.
cVIS-QM achieved technical feasibility, validated user need, and defined a user-informed MVP, enabling widespread adoption of cryogen-free dilution refrigerators for quantum research.

Results Overview:
The cVIS-QM project achieved three main outcomes:
Technical feasibility: Installed a compact cryogenic vibration isolation (cVIS) system in a cryogen-free dilution refrigerator, enabling sub-nanometer STM imaging with both pulse tubes active.
Market validation: ~10 interviews and 70+ discussions confirmed strong demand for retrofit vibration isolation for SPM and levitation-based sensing.
MVP definition: Specified a product for Bluefors LD cryostats with <0.5 Hz resonance, -100 dB attenuation, passive, non-magnetic, magnet-compatible, and <24h additional cooldown.
Potential Impacts:
Scientific: Enables high-resolution SPM (AFM, STM, SQUID-on-tip) at milli-Kelvin temperatures, advancing qubit metrology and adoption of cryogen-free systems.
Industrial: Opens markets in quantum computing and nanotechnology, supports device fabrication, and strengthens Europe’s cryostat competitiveness.
Economic/Societal: Reduces helium dependence, accelerates scalable quantum computing, aligns with Quantum Flagship and Chips Act goals.
Next Steps:
Further R&D across SPM techniques and platforms, finalize MVP, secure IP, engage early adopters, access funding, and align cVIS as a standard module in European quantum infrastructure.
