Precision Positioning for Quantum Technologies

QuVac provides cryogenic nanopositioning, scanning, and optical solutions for demanding quantum research environments, including dilution refrigerators, superconducting quantum systems, scanning probe microscopy, quantum sensing, trapped-ion platforms, and ultracold-atom experiments.

Our portfolio focuses on technologies that remain reliable under extreme conditions.

Tested Before Delivery

One of the major differentiators of Multifields technology is the validation process.

Unlike many nanopositioning systems that are primarily characterized at room temperature and subsequently assumed to operate correctly at low temperatures, Multifields performs cryogenic quality control testing of motion components before shipment.

This approach helps ensure:

>Reliable low-temperature performance
>Reduced commissioning risk
>Improved reproducibility
>Greater confidence in demanding experiments

For researchers operating dilution refrigerators and cryogenic quantum platforms, this verification process can significantly reduce integration time and experimental downtime. All the products are delivered with detailed room temperature as well as the low temperature test reports!

Closed-Loop Cryogenic Scanners (New!)

The flagship platform is Multifields’ closed-loop 25 mm/35 mm series scanners (Product Name: Scanner25.Ultra/35.Ultra), utilizing capacitive position feedback for true closed-loop operation at cryogenic temperatures. No laser interferometer based feedback required !

Advantages over Interferometric Feedback

> No optical fibers
> No fiber vacuum feedthroughs
> No laser heat load (~100 µW saved per axis)
> No optical alignment at cold
> Simpler cryostat integration

To the best of our knowledge, this represents the world’s first laser-free closed-loop cryogenic scanner capable of operating under these combined extreme conditions down to 10mK and 35 Tesla magnetic fields.

Cryogenic Nanopositioners

Default closed-Loop sensor integration without the Footprint Penalty

Unlike many conventional cryogenic nanopositioning systems, Multifields nanopositioners feature integrated resistive closed-loop position control as a standard capability rather than an optional add-on. The position feedback system is incorporated without increasing the overall device footprint, preserving valuable experimental space inside cryostats, vacuum chambers, and high-field magnet systems.

The result is true closed-loop positioning performance without the size, complexity, or integration compromises often associated with external feedback solutions.
In addition to the flagship Scanner25/35.Ultra line close-loop scanners, QuVac offers a broad range of closed-loop nanopositioners for:

>Sample positioning
>Optical alignment
>Scanning probe microscopy
>Quantum sensing
>Cryogenic instrumentation
