Microwave packaging with minimal losses and decoherence

Get the Spec SheetRequest a Quote

QCage are sample holder systems for microwave resonator based quantum devices. The product range features both the relatively compact QCage.24 for versatile and flexible microwave measurements and the upscaled QCage.64 for operating quantum processors with up to 30 qubits. These provide optimal solutions with regards to both performance metrics for coherent operations and ease-of-use in a lab workflow.

QCage.24

QCage.24 is a versatile sample holder system which fit into most common sample loader puck systems but can also be mounted directly into a fridge with options for both perpendicular out-of-plane and flat in-plane mounting configurations. The QCage.24 is equipped with a low-loss PCB with 24 embedded coplanar transmission lines. It supports up to 10 qubits providing flexibility for a wide range of experiments. The optimized cavity and PCB is optimized to ensure resonance-free transmission up to 18GHz. An EMC tight superconducting enclosure minimizes electromagnetic interference, while an internal flux biasing magnet offers precise control for your experiments.

QCage.64

QCage.64 takes quantum research to new heights with its expanded capacity, supporting up to 30 qubits using the 64 embedded transmission lines. Optimized for resonance-free transmission up to 8 GHz, this system is designed for peak performance. Like its counterpart, QCage.64 features an EMC tight superconducting enclosure for electromagnetic compatibility. The inclusion of a flux biasing magnet inside the shielding guarantees precise control and stability for your experiments.

Magnetic Shielding

QCage Magnetic Shielding is available for both QCage.24 and QCage.64, providing unparalleled protection and thermalization. Featuring a top flange plate with convenient mounting holes for easy loading, this shielding consists of a special cryogenic alloy that creates an outer mu-metal shield to avoid flux trapping. An inner superconducting Al can surface, treated and sleeved by copper, achieves full Meissner effect shielding, eliminating external stray magnetic fields and radiation. Two variants with either 24 SMA or 64 SMP connections offer flexibility, and QCage.64 can accommodate one QCage.64 unit or two QCage.24 units.

Saved two years of development

“Developing a functional qubit control electronic system absorbs a PhD-student full time at least for two years. QM’S Quantum Orchestration Platform allowed us set up experiments for full qubit characterization in 2-3 days with an undergraduate summer school student.”

Revolutionizing spin qubit control, all in one box

“The quantum orchestration platform (QOP) platform completely changed the way we control semiconductor quantum dot spin qubits. Key qubit control schemes we previously developed individually using time-consuming hardware description languages are now easily implemented in one box.”

Simplified lab workflow and faster runtimes

“Replacing three devices with one synchronized, orchestrated machine tremendously simplified lab workflow. Now our pulse sequences run in a fraction of the time of any other device combo. Plus, we can “talk” to the FPGA in human-speak, to run real-time calculations that were too complicated before! Along with the yoga-level.”
