SEEQC Uses FormFactor’s Qubit Pre-screening Solution to Speed Quantum Computing Development

PRESS RELEASE — FormFactor, Inc. (NASDAQ:FORM), a leading semiconductor test and measurement supplier, today announced that SEEQC, the Digital Quantum Computing company, has deployed FormFactor’s recently announced integrated measurement solution to markedly expedite its quantum computing research and development program. The measurement solution, including the sub-50mK HPD Model 106 Adiabatic Demagnetization Refrigerator (ADR) and the PQ500 RF and DC probe socket, complements sub-10mK dilution refrigerators to accelerate cryogenic test cycles by more than two times.

As the quantum computing industry matures and scales up the number of qubits for commercialization, accelerating test cycles becomes a priority. FormFactor’s innovative new PQ500 high-density probe socket, the first commercial product of its kind, allows scientists to directly probe quantum computing processor dies inside ultra-low temperature cryostats like ADRs.

“Wire-bonding of high-performance quantum and classical superconducting integrated circuits is a time-consuming, low reliability process that is a common hassle for many cryogenic electronics developers,” said Oleg Mukhanov, CTO of SEEQC, a developer of quantum computing systems in which superconducting qubit and single flux quantum (SFQ) chips are combined to achieve high system scalability.

“With FormFactor’s probe socket solution, we have been able to eliminate wire-bonding for qubits, SFQ circuits, and multi-chip modules for faster device characterization to identify the known-good die for final quantum testing. This has streamlined and improved our device characterization process especially in providing fast feedback to our foundry fabricating superconducting integrated circuits and multi-chip modules.”

“SEEQC is an early adopter of FormFactor’s innovative test technologies. Our collaboration with SEEQC delivers the capability that truly addresses the unique test and measurement challenges with the emerging quantum computing industry,” said Amy Leong, Senior VP and General Manager of the Emerging Growth Business Unit at FormFactor. “It’s one more step on our roadmap to bring productivity innovations as the quantum computing market matures.”

Key System Features

FormFactor’s quantum cryogenic measurement system incorporates:

HPD Model 106 ADR Cryostat

  • Pulse tube cryocooler for cryogen free 4K temperatures
  • Two stage ADR provides solid state cooling down to 30mK
  • Sample stage mounting at both 1K and 50mK

PQ500 High Density RF and DC Probe Socket

  • Comprehensive I/O connections: standard setup of up-to 24 RF lines (up to 18 GHz) and 48 DC lines, with extensions to higher I/O connections possible
  • Non-magnetic construction: capable of characterizing qubits below 50mK without magnetic interference when required
  • Sample size: proven with chips up to 10mm x 10mm in size
  • Pressure-based contact: provides test and measurement connection to DUTs (Devices Under Test) using pressure only — no permanent connection required
