2024 marked a turning point for quantum computing stocks. IBM’s latest quantum processor wasn’t just another research milestone – it sparked a wave of serious investor interest in quantum technology. Now, with market forecasts pointing to $65 billion by 2030, more investors are eyeing this space. But here’s the reality check: not every company with “quantum” in its press releases is actually building working quantum computers. Some are pushing boundaries and creating real breakthroughs. Others? They’re mostly selling dreams.
