Zacks thinks quantum computing is the next big opportunity for investors looking past AI. The market is expected to cross $1 billion in 2026 with funding already doubling over the last year. The Defiance Quantum ETF (QTUM) has already seen big gains recently. They highlighted three stocks to watch: * **IonQ (IONQ)** is a pure-play focusing on scaling to 256+ qubits by 2026. * **IBM** has its Nighthawk processor and aims for quantum advantage next year. * **NVIDIA (NVDA)** is using its CUDA-Q platform to help researchers integrate quantum with GPUs. It's still a volatile sector, but money is pouring in from governments and corporations.
