Quantum computers can perform certain computational tasks much faster than classical computers. Unlike classical bits, which store their data in zeros and ones, qubits (quantum bits) can exist in superpositions of states to simultaneously explore more possibilities. That sounds like a major leap forward in computing, but quantum computers are also larger, pricier, and consume more power than their classical counterparts. They also output a higher percentage of errors. That's why they're still primarily used for niche research projects rather than mainstream computing applications. Nevertheless, the quantum computing market could still expand at a 30.6% CAGR from 2026 to 2034, according to Fortune Business Insights, as those systems become smaller, more scalable, more affordable, and more accurate. That rosy outlook sent many quantum stocks soaring to record highs last October. Still, most of the top names subsequently pulled back as macro headwinds rattled the market and drove investors away from the speculative sector. One such quantum stock was IonQ (IONQ +2.69%), which has dropped nearly 50% from its all-time high. However, I believe IonQ could be the first quantum stock to prove the bears wrong and generate massive gains over the next decade for a few simple reasons. What does IonQ do? Most quantum computing systems accelerate electrons through superconducting loops to process data in a quantum state. Those electron-based systems are cheaper to manufacture than more advanced systems, but they must be cryogenically cooled. By comparison, IonQ develops "trapped ion" systems that trap ions in an electromagnetic field within a vacuum chamber and manipulate them with tiny lasers. These room-sized systems are much larger than electron-based systems, but they don't require any refrigeration.
