Optical Qubits
Harnessing the photon as a quantum information carrier, optical quantum computers rely on ultra stable experimental conditions at low temperature.
ARS’ Ultra-Low Vibration Cryostats are optimized for photonic qubit, nitrogen-vacancy centers, and quantum dots, due to:
Ultimate Sample Stability Relative to the Optical Table, isolating cryocooler vibrations and mechanical drift to the nanometer scale.
Low Working Distance and Low Beam Height Transmission-Mode Optics, seamlessly integratable into complex optical setups.
Endlessly Configurable Sample Chamber, featuring multiple large windows, in-vacuum objectives, and sample motion.
Superior Cryogenics, building on over 30 years of cryostat development.
The 4K sample plate of the microDrift cryostat features a breadboard mounting pattern for flexible mounting of sample holders and accessories.
Superconducting Qubits
When cooled to a sufficiently low temperature, materials in superconducting quantum computers such as Niobium reach a state of zero electrical resistance.
To meet these temperature needs, ARS designs and builds cryogenic probe stations suited for rapid characterization with the following advantages:
Fast Vacuum Pumping, Cooldown and Warmup, completing a full sample exchange of a 4” wafer in as little as 130 minutes.
Advanced Probe Thermalization, allowing <5K sample temperatures with four probes in contact.
Unmatched build quality, made of fully-welded stainless-steel vacuum chambers and house-built micromanipulators.

Trapped Ion Qubits
Manipulating the electron states of individual atoms requires a cold, stable environment in a pristine vacuum.
ARS offers a wide range of suitable UHV cryostats for ion trapping, featuring:
True Ultra-High Vacuum Chambers, including all welded stainless-steel connections, and metal seals rated to 1e-12 mbar.
Ultra-Low Vibrations, minimizing coldhead vibrations below 5 nm, peak-to-peak.
High cooling power, efficiently overcoming the high heat loads of demanding applications.
This ultra-low vibration UHV cryostat was customized with a manipulator for an ion trapping experiment.
Quantum Control Electronics (Cryo-CMOS)
Developing electronics to control qubits often involves repeated iteration and testing.
Scale-up faster with our cryogenic electrical characterization platforms, specialized for:
Rapid Cooldown, reaching < 3.0K in as short as 75 minutes.
Large, customizable breadboards, allowing numerous samples to be mounted flexibly.
Numerous measurement wires, ranging from low-heat load DC lines to high frequency RF cables..
Our non-optical cryostats are frequently built with large breadboard cold plates within spacious vacuum chambers with sufficient space for dozens of DC wires and high frequency RF cables.
Spin Qubits
Semiconductor quantum dots can be controlled by magnetic fields in cryogenic, low-noise environments.
Our cryogenic probe stations and cryostats are equipped with:
Strong magnetic fields, available up to 6T within the sample chamber.
Low-noise, biasable sample plates, isolated with coaxial or triaxial shielding.
The sample plate of this cryogenic probe station is placed in the bore of a superconducting magnet. The plate and the magnet are cooled independently by dedicated cryocoolers.
