QTREX says printed coaxial quantum interconnect meets partner RF performance targets

QTREX reported its printed coaxial quantum interconnect platform exceeded RF performance thresholds set by strategic partners in qualification testing.

• Testing showed continuous transmission from 10 MHz to 20 GHz with no observed resonance, notch, or discontinuity across measured channels.
• Crosstalk suppression held at least 68 dB below the source signal across the measured frequency band.
• Channel matching averaged 4.4 picoseconds skew above 1 GHz; group delay was 1.020–1.022 nanoseconds, a 2-picosecond spread.
• Results are expected to support commercialization work on high-density connectivity components for scalable quantum control and readout systems.
