QTREX Quantum is trading 17.61% up at $0.92 after announcing independent cryogenic interconnect test results. - Testing at 20 millikelvin showed channel isolation above 100 dB; the company is finalizing a binding agreement with the testing customer. - This follows a second consecutive strong session, after a 15.04% gain on October 1. - Benzinga linked Friday’s rise to the announcement; broader indices were higher, but company news was the clearest reported catalyst. QTREX’s release did not explicitly attribute the move to results.
