Proteox 5mK

Lower electron temperatures and improve resolution of quantum states for new material characterisation.

Characterise exotic quantum states
Investigate exotic quantum states such as Majorana Fermions and Fibonacci Particles for next generation qubit development using the fractional
quantum Hall effect

Reduce measurement error
Lower temperatures reduce measurement errors to enable further improvements in metrological standards

Explore quantum thermodynamics
Uncover the quantum nature of heat, with applications towards quantum refrigerators and improved ultra low temperature thermometry

Increase qubit coherence
Lower temperatures have the potential for increased qubit coherence times for quantum computing and quantum annealing

Low vibration for reduced eddy
current heating
High stiffness, flexible bellows and optimised
resonance to reduce pulse tube oscillations and harmonics eliminate the need for active vibration damping

Easily install experiment services
Clear system plate layout maximises space and ease of access for experiment assembly

High capacity for flexible wiring and line-of-sight access
Six line-of-sight ports and nine non-line of sight ports for DC and coaxial wiring

Expanded temperature range for high field experiments
Active gas gap heat switches enable control to above
30 K at full field and rapid return to base temperature In less than 4 hours

Lower electron temperatures with the world’s coldest dilution unit
The world’s coldest commercially available continuous operation Cryofree® dilution unit provides ultra-low base temperature of < 5 mK and high cooling power of > 25 μW at 20 mK for optical access and Piezo positioners

Active Magnetic Field Cancellation
Our actively cancelled magnets ensure the lowest possible experimental base temperature through reduced Eddy current heating, with cancellation to
< 100 Gauss at the mixing chamber plate

The world’s coldest commercially available continuous operation Cryofree® dilution unit provides ultra-low base temperature of < 5 mK and high cooling power of > 25 µW at 20 mK.

System

• Fully redeveloped gas handling system to ensure the minimum number of connections for long term mixture retention
