Shares of D-Wave Quantum (NYSE: QBTS) jumped Monday morning on the announcement that AT&T (NYSE: T) is expanding its use of the company's quantum computing technology across its network operations. This is excellent news in a rough year for D-Wave's stock, which is down more than 26% in 2026.

So should investors buy D-Wave Quantum's stock now?

Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue »

This new agreement with AT&T expands on a pilot program that demonstrated D-Wave's annealing quantum computing cut processing time for a network optimization workload by 240x, from approximately one hour to 15 seconds.

Ultimately, this result with AT&T could catalyze D-Wave as other companies take notice of the real-world results from the pilot program. The quantum computing industry as a whole could use a boost, having largely lost investor enthusiasm this year after a 2025 run-up.

D-Wave's stock is still highly speculative and volatile. The commercial applicability of quantum commuting is largely unknown and untested. This nod of credibility from AT&T should help. Investors in D-Wave need to proceed with patience and caution, however, as the company has relatively little revenue compared to its losses.

On the positive side, D-Wave has more than $42 million in remaining performance obligations (RPO), a 563% year-over-year increase. The AT&T deal, paired with this jump in RPOs, could signal real traction for D-Wave's technology.

With the stock down significantly in 2026, risk-tolerant long-term investors willing to tolerate continued volatility may see the AT&T deal as the cue to climb aboard.
