The Quantum Spy

David Ignatius's 2017 techno-thriller follows a covert race between the CIA and Chinese intelligence to obtain a breakthrough in quantum computing. The intelligence agencies treat the technology as a strategic advantage, not merely as a scientific research project.

It is primarily an espionage thriller, using quantum computing as the reason for the conflict between the CIA and Chinese intelligence. Readers get spycraft, recruitment, surveillance, and geopolitical maneuvering alongside the technology premise.

The novel was written by David Ignatius, an American journalist and author known for political and intelligence fiction. It was published in 2017 and belongs to the modern techno-thriller tradition.

Quantum computing could affect encryption, communications security, and strategic intelligence, so the technology becomes a national-security asset. That premise drives the race between the CIA and Chinese intelligence throughout the book.
