When it comes to quantum technology (QT), investment is surging and breakthroughs are multiplying. The United Nations has designated 2025 the International Year of Quantum Science and Technology, celebrating 100 years since the initial development of quantum mechanics. Our research confirms that QT is gaining widespread traction worldwide. McKinsey’s fourth annual Quantum Technology Monitor covers last year’s breakthroughs, investment trends, and emerging opportunities in this fast-evolving landscape. In 2024, the QT industry saw a shift from growing quantum bits (qubits) to stabilizing qubits—and that marks a turning point. It signals to mission-critical industries that QT could soon become a safe and reliable component of their technology infrastructure. To that end, this year’s report provides a special deep dive into the fast-growing market of quantum communication, which could unlock the security needed for widespread QT uptake.
