D-Wave Quantum (NYSE: QBTS) saw its stock surge after the Florida-based company unveiled an expanded commercial partnership with AT&T (NYSE: T) on Monday.
The deal centers on AT&T’s use of D-Wave’s signature annealing quantum computers, marking a significant deepening of ties between the two companies.
In the quantum computing sector, commercial partnerships are widely regarded as among the strongest indicators of real-world technological progress and viability.
The relationship between D-Wave and AT&T is not a new development, as the two organizations have been building toward this expanded agreement for some time.
D-Wave first signaled the collaboration earlier in 2026, when representatives from AT&T appeared at D-Wave’s annual user conference as participants.
That early appearance by AT&T representatives was seen at the time as a meaningful indicator that a more formal commercial arrangement was in development.
The expanded partnership now confirms what many observers suspected, placing AT&T among D-Wave’s most prominent enterprise-level clients in the telecom sector.
Annealing quantum computing, D-Wave’s core technology, is designed to solve complex optimization problems, which are particularly relevant to large-scale telecommunications network operations.
AT&T’s decision to deepen its involvement with D-Wave’s quantum technology reflects growing corporate interest in quantum solutions for real-world operational challenges.
The announcement sent QBTS shares sharply higher, while AT&T stock also gained ground, rising approximately 5.10% following the news of the expanded arrangement.
By contrast, rival quantum computing companies including IonQ (NYSE: IONQ) and Rigetti Computing (NASDAQ: RGTI) saw their shares decline, falling 3.61% and 4.71% respectively on the same trading day.
The divergence in stock performance underscores how commercially meaningful partnerships can distinguish individual players within an otherwise volatile and speculative quantum computing market.
