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 optical qubit testing due to:

• Ultimate Sample Stability, isolating cryocooler vibrations and mechanical drift to the nanometer scale.

• Endlessly Configurable Sample Chamber, featuring multiple large windows, low working distance, in-vacuum objectives, and sample motion.

• Superior Cryogenics, building on over 30 years of cryostat development.

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, cooldown and warmup, completing a full sample exchange of a full 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.

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, 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 high heat loads of demanding applications.

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..

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.
