Advancing RF Density with the Quantum-Proven PkZ

Quantum Computing Products


Quantum computing is a rapidly evolving science with the potential to lead to breakthroughs in diverse applications and industries. Phoenix supports Quantum Computing customers through increased density of microwave cables and attenuators along with a growing level of solutions for bringing signals onto the quantum processor board.

HDQ™: Complete Quantum Processor Board Connections

Quantum proven PkZ® constant impedance contacts are ideally suited to connect a high density of microwave lines to the quantum processor board. The Phoenix Company’s new HDQ connection system leverages the PkZ’s size, density, and reliability to produce a complete board-level microwave solution.

Developed to mate with existing dilution refrigerator and cryostat RF lines, the system provides a straightforward and efficient path to increased board level density. The HDQ-18, rated for 18 GHz performance, is the first series in this new family of products. The system includes board mount receptacle contacts and housings as well as cable harnesses consisting of PkZ to SMA cable assemblies with a plug side housing. There are 3 different housing sizes to select from with full density providing 188 board level connections spread over 4 small-footprint housings.

Once installed, up to 47 microwave lines can be connected in a single plug-in operation!

High Density Modular Connections for Dilution Refrigerators and Cryostats

A quick-connect system for cryogenic-based Quantum Computing applications is available featuring our patented non-magnetic PkZ connection technology. This system replaces existing RF connectors and cables with a higher density of connections from external microwave cables through the hermetic header into each level of the dilution refrigerator or cryostat down to the Quantum processor.

The heart of this system is the blindmate constant impedance PkZ contact. Designed with optional embedded attenuation for mass-interconnection, the system replaces thread-on SMA connectors and attenuators. PkZ housings fit existing dilution refrigerators with up to 64 RF lines per port while simplifying mating of all 64 lines with one plug-in operation.

The Phoenix Company’s Quantum Computing-focused designs are highly adaptable and can be modified to suit various cable types and dilution refrigerator or cryostat requirements. Our vertical integration and proximity to North American customers allows Phoenix to partner with customers to develop unique cryogenic connector solutions.

SMA Cables

The Phoenix Company specializes in custom Low Temperature Microwave Cable Assembly solutions based on our carefully designed, low temperature SMA connectors. These unique, non-magnetic SMAs come pre-cabled on CuNi semi-rigid coaxial cable rated for cryogenic environments. All SMA cable assemblies are designed and manufactured for reliable performance over repeated thermal cycles.
