QTREX Interconnect Independently Tested at 20 mK by a Leading Quantum Computing Company; Over 100 dB Channel Isolation, 60 dB Beyond the Market Leader
QTREX Quantum announced independent testing of its AME cryogenic interconnect at 20 millikelvin by a leading quantum computing company, confirming better than 100 dB channel isolation across the 4-8 GHz qubit band. The result exceeds the published 40 dB crosstalk specification of the leading flexible cryogenic cabling by more than 60 dB, with insertion loss of about 1 dB at 1 GHz and 2 dB at 6 GHz including connectors. On the strength of the results, QTREX and the unnamed testing company are finalizing a binding definitive agreement, with the counterparty's name and terms to be disclosed within weeks.
