QTREX Quantum’s cryogenic interconnect was independently verified at 20 millikelvin by a leading quantum computing firm, recording more than 100 decibels of channel isolation across the 4-to-8 gigahertz qubit band. The result exceeded market-leading flexible cabling by more than 60 decibels, with no detectable crosstalk. QTREX said it is finalizing a binding definitive agreement with the testing customer and expects full commercial disclosure within weeks, alongside additional fourth-quarter commercial deals. Shares rose 12.43% to $0.88 in Friday premarket trading, according to Benzinga Pro data.
