kiutra | Simplified and fast cryogenics for quantum technologies

At kiutra, we make cryogenics accessible. We give quantum teams fast, easy access to kelvin and millikelvin temperatures through our systems, services, and rental. And it’s helium-3-free – no dependency on one of the world’s scarcest resources.

L-Type Rapid

The fast-feedback characterization cryostat for sub-kelvin and kelvin temperatures

Fast, cost-effective access to cryogenic temperatures – automated sample loading and simplified operation take the maintenance and waiting out of low-temperature characterization.

X-Type

The cooling architecture for scalable quantum systems

A modular, helium-3-free cooling architecture that separates cooling infrastructure from the quantum setup, so cooling power and system complexity can scale independently.

< 12 mK

Superconducting qubits

< 100 mK

Spin qubits

Scales horizontally with added cooling modules, or vertically by upgrading the payload alone.

Optical 4 K cryostat purpose-built for trapped-ion quantum computing R&D

The T-Type combines closed-cycle 4 K cooling, metal-sealed XHV vacuum, vibration decoupling, and 360° free-beam optical access in a single platform, giving ion traps a stable, long-lifetime environment with full optical control.

Integrated RF and DC wiring for trap operation.
Deploy on an optical table or integrate into a standard 19″ rack.
Optionally available with a dedicated, hermetically sealed ion trap vacuum chamber, enabling fast trap exchange and superior vacuum conditions.

Working with the L-Type Rapid cryostat has been a great experience. The fast-loading mechanism combined with the provided 48 DC contacts, allowed us to quickly check our samples down to 100 mK. Since all the API was written in Python, we could very easily create drivers to integrate the magnet and temperature controls into our measurement programs. These combined ensured a very smooth transition to incorporate the system into our day-to-day sample characterization.

The kiutra system effectively bridges the gap between dilution refrigerators and cryostats, providing a reliable and efficient solution. Its cADR stable temperature control ensures precise and consistent performance. Additionally, the after-sale service is fast, efficient and highly supportive. I recommend it to anyone looking for a system that allows quick sample exchange and efficient characterization.

The unique combination of fast cooling to 100–300 mK, sufficiently large sample space, both RF and DC lines and a several tesla sample magnet enables both the experimental education in quantum mechanics and the characterization of materials and sub-components of qubits, specifically spin-qubit and superconducting qubits.

Quantum technologies are rapidly expanding, and have reached a maturity where the available technology and tools in a lab make the difference. Nanofabrication facilities enable us to create complex qubits and amplifiers, which now require an increasing degree of control only accessible through an extensive (statistical) knowledge of the circuits and materials at or below 100 mK. The kiutra L-Type Rapid is a paradigm changer in this context, as it allows up to 3 test runs per day at 100 mK, with a setup compatible with the most advanced microwave characterizations and qubit measurements. Our model includes a vector magnet (1T/0.15/0.15) which enables ESR and other hybrid, spin or 2DEG devices pre-characterization. State of art measurements can also be performed at low frequencies in the same platform. We are thrilled (an envied) to have such a tool at SPEC!

It is a great experience to work with the L-Type Rapid, really plug and play and we could do measurements from day one. And the Cryogenics as a Service helped us to bridge the time before the delivery and accelerate our cryo-CMOS developments. Looking forward to characterize our cryogenic control electronics for our ion traps with the new cryostat.
