ionq vs rgti vs qbts which quantum computing stock should you buy in

Quantum computing has quickly emerged as one of the most exciting new narratives in the market, producing some of the best-performing stocks over the past year. Shares of D-WAVE QUANTUM (QBTS), IonQ (IONQ), and Rigetti Computing (RGTI), three of the industry’s leading names, have surged anywhere from 500% to 1,600% in the last twelve months as investors priced in the... More recently, however, momentum has cooled. Throughout much of 2025, the sector has traded sideways, with QBTS still showing gains while others have flattened or pulled back. The developments in quantum remain thrilling, but these stocks are still highly speculative, and success for investors depends as much on timing and risk management as on the technology itself. In this article, I’ll break down the technical picture for each of these quantum leaders and outline how investors may want to approach trading strategies and risk management in this rapidly evolving sector.

D-Wave Quantum is one of the pioneers of quantum computing, known for its annealing-based quantum systems designed to solve optimization problems. While its approach differs from the gate-based systems pursued by rivals, D-Wave has built a strong base of commercial partnerships and continues to expand its cloud-accessible quantum services. The price action in QBTS stock provides a clear snapshot of what’s happening across the sector and sets the tone for what investors should expect. As promising as the industry appears, the market’s current positioning leaves some ambiguity about where these stocks will head next. Fortunately, by watching the technical picture closely, we can identify some key levels. The quantum computing space has been heating up rapidly, but we’re still in the early stages.

This means IonQ (NYSE:IONQ), Rigetti Computing (NASDAQ:RGTI), and D-Wave Quantum (NYSE:QBTS) have all been lifted by the rising tide. But if that tide continues rising, or once commercially viable quantum computing (or QC) becomes a reality, not every QC startup has the buoyancy to rise all the way to the top. Almost every quantum computing startup has its own way of trying to make QC commercially viable. There will only be a handful of direct QC winners. And it is debatable whether or not the biggest winner will be from the current batch of QC companies that are publicly tradable. OpenAI was the first AI company to achieve a breakthrough, despite public companies having their own AI teams with deeper pockets.

With that in mind, it requires careful consideration before you pick between the popular quantum computing stocks in the market right now. If you’re in it for the long run, it’s even more important to research them individually and determine which one will ultimately prevail. Let’s take a look. IonQ has historically led the quantum computing startup space, and it does have very impressive tech. It has the lowest error rates in the QC business, with 99.99% fidelity on two-qubit gates. As of today, it has Forte, with 36 physical qubits.

It already has customers. Namely, Airbus (OTCMKTS:EADSY), Hyundai, and the U.S. Air Force. IonQ Tempo has 64 algorithmic qubits.
