Could Quantum Chips Be the Next "Atomic Bomb"?

A capability, not a single weapon

Quantum chips are being cast in stark metaphors: like the atomic bomb, they are said to change the balance of power overnight. Why the comparison? Because a sufficiently powerful quantum computer could run Shor’s algorithm to factor large integers far faster than today's classical machines, threatening the public‑key cryptography that underpins banking, government communications and military networks. Google’s 2019 Sycamore milestone—announcing “quantum supremacy” for a narrow task—was a wake‑up call. But unlike a single detonation, quantum advantage will arrive as a diffused, incremental capability that reshapes sectors over years and decades.

Cryptography, competition and national mobilization

The immediate fear is systemic: encrypted archives and long‑lived secrets could suddenly be exposed. In response, the U.S. National Security Agency urged agencies to migrate to post‑quantum cryptography in 2023. Governments are not standing idle. China has listed quantum information among priority frontiers in its 14th Five‑Year Plan; the EU runs a Quantum Flagship program; and it has been reported that U.S. lawmakers have approved more than $1.2 billion in bipartisan funding for quantum research. Export controls matter too — in 2022 the U.S. placed advanced quantum tools on a restricted list, tightening technology flows to China and sharpening the geopolitical stakes.

Two camps, many technical routes

The race is as much about physics and engineering as it is about funding. Superconducting qubits—pursued by Google, IBM, Intel and China’s Origin Quantum (本源量子)—leverage existing semiconductor know‑how but demand extreme cryogenics and face coherence limits. Photonic approaches, championed by teams including Pan Jianwei (潘建伟) at the University of Science and Technology of China (中国科学技术大学), promise room‑temperature operation and long coherence for certain tasks. It has been reported that in late 2024 Google and the University of Science and Technology of China each unveiled roughly 105‑qubit processors, underscoring how different architectures are advancing in parallel. Reportedly, firms such as Microsoft and IBM are chasing error‑correction breakthroughs that could tilt the field again.

China’s longtime buildup and the longer view

China’s quantum push has deep roots—from early pioneers like Guo Guangcan (郭光灿) to startups such as Origin Quantum. It has been reported that China achieved a series of high‑profile milestones in 2024–2025, including claims of new processors and prototype systems described as demonstrating quantum advantage. Caveats remain: qubit counts alone are an incomplete metric; coherence times, gate fidelity and system integration matter more for meaningful applications. So will quantum chips become an “atomic bomb” of the information age? Not in a single flash. But as a strategic capability they can create asymmetric advantage, disrupt encryption, accelerate material and drug discovery, and redraw tech geopolitics — and that is why nations are racing to master them.
