Quantum Open Architecture (QOA) & Quantum Systems Integration: From Monoliths to Modular Quantum Computing

Today's quantum computers are monoliths — a single vendor designs the chip, builds the control electronics, writes the software, and operates the cloud platform. The customer gets a black box. This is exactly where classical computing was in the 1960s, ...

Underestimating China: Why Beijing Could Win the Quantum Race

Nine investigations. One conclusion. China's structural advantages in quantum technology make it the most dangerous competitor the West has ever underestimated. Over the past several months, I examined every dimension of China's quantum program — the industrial policy that elevated ...

China’s Quantum Supply Chain: How Export Controls Are Building What They Sought to Prevent

In June 2023, a Zhejiang University graduate named Chen Jie sat for an interview with a Chinese tech columnist. Chen had founded a cryogenics company called CSSC Pengli in Nanjing thirteen years earlier — a subsidiary of China State Shipbuilding ...

China’s Quantum Sensing Ecosystem: From Deep-Sea Diamonds to Drone-Mounted Submarine Hunters

In April 2025, a team from the University of Science and Technology of China published what might be the most consequential quantum sensing result of the decade — and almost nobody in the Western security community noticed. They had taken ...

OT Security in the Age of AI Exploits: What Anthropic’s Mythos Preview Means for Critical Infrastructure

On April 7, 2026, Anthropic disclosed Claude Mythos Preview, an AI model that autonomously discovers and exploits zero-day vulnerabilities in every major operating system and web browser. As I detailed in my analysis of the announcement, these capabilities represent a ...

China’s Quantum Networking and QKD — World’s Most Ambitious Quantum Communication Program

On September 29, 2017, a video call connected two men separated by 7,600 kilometres. On one end, in Beijing, Bai Chunli, president of the Chinese Academy of Sciences. On the other, in Vienna, Anton Zeilinger, the physicist who would later ...

China’s Quantum Computing Hardware: The Core Capability the West Keeps Misjudging

The published record suggests China trails the US by about a year. The actual gap may be narrower — or it may already be closed. In December 2025, a team at the University of Science and Technology of China quietly ...

China’s Quantum Talent Ecosystem: Building a Superpower’s Workforce

In 1996, a 26-year-old physics student from the University of Science and Technology of China arrived in Vienna to begin doctoral work under Anton Zeilinger, one of the world's leading quantum experimentalists. Five years later, he went home. That decision ...

China’s Hefei National Laboratory: The Nerve Center of a Quantum Superpower

On April 26, 2016, Xi Jinping walked into USTC's Advanced Technology Research Institute in Hefei and listened to a physicist named Pan Jianwei describe the future of quantum information science. What Xi said next — "Very promising, very important… the ...

The $15.3 Billion Number That Everyone Cites and Nobody Can Verify

In October 2023, I was on a call with a European defense ministry official who wanted to discuss quantum threats. Within the first five minutes, he cited it. "China has invested $15.3 billion in quantum technology - nearly double the ...

China’s 15th Five-Year Plan Makes Quantum an Industrial Imperative — Not Just a Research Priority

When China's National People's Congress approved the 15th Five-Year Plan on March 12, 2026, it completed a journey that had been building for over a decade. Quantum technology, once buried deep in academic research budgets, emerged at the top of ...

The CRQC Scorecard: How Close Is Each Quantum Modality to Breaking Your Encryption?

Yesterday, two papers landed that set social media on fire. Google Quantum AI published a landmark resource estimate showing that fewer than 500,000 superconducting qubits could break Bitcoin's elliptic curve cryptography in under nine minutes. Hours later, a team from ...
