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.

Disentangling Losses in Tantalum Superconducting Circuits

“QM’s chip packaging solutions are exquisite pieces of engineering that have enhanced our resonator Q-factors to as much as 200 million. It is clearly a very highly engineered product that I’m sure will be widely adopted in the field.”

PhD Student, Kevin D Crowley Houck Lab, Princeton University

iSWAP with multiplexed readout​ in 10 lines of QUA code​

“We were extremely surprised by the flexibility that OPX offers and by how much easier it makes our experiments. Moreover, OPX provides extreme speed-ups. No more frustration due to long waiting times for unwanted results!”

Prof. Tse-Ming Chen National Cheng Kung University, Taiwan

Innovative engineering and higher research throughput

“QCage integrates seamlessly into our workflow of preparing and loading QPUs and supports higher throughput in our lab. Our research directly benefits from QCage's innovative design and engineering.”

Prof. Javad Shabani New York University

Q-factors as high as 200 million

“QM's chip packaging solutions are exquisite pieces of engineering that have enhanced our resonator Q-factors to as much as 200 million. It is clearly a very highly engineered product that I am sure will be widely adopted in our field.”

Kevin Crowley Houck Lab, Princeton University

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.”

Prof. Gerhard Kirchmair University of Innsbruck

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.”

Prof. Dohum Kim Seoul National University

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.”

Prof. Amit Finkler Weizmann Institute of Science

This system will revolutionize our space

“The first time I was introduced to Quantum Machines, It surprised me how people were getting so excited about it. Only later did I realize, it was like explaining the value of a Laser before it existed, and all you knew are light bulbs. Today I truly believe that these systems will revolutionize our space.”
