THE QUANTUM ARMS RACE HAS A BASELINE PROBLEM

Summary from the TLDR Hardware newsletter

As the US and China both push quantum computing, sensing, and networking as strategic priorities, the real question isn't who's ahead but ahead of what, since a quantum advantage is only meaningful relative to the classical system it's compared against. Quantum radar is the clearest case: the underlying physics of quantum illumination is real and has shown genuine detection gains in controlled lab conditions, but a laboratory advantage doesn't automatically translate into a long-range operational radar advantage once range, clutter, atmospheric loss, and receiver complexity enter the picture. The same trap applies to quantum machine learning and quantum computing broadly, where a system can look superior on paper simply because it was benchmarked against a weak or poorly optimized classical competitor rather than the best available alternative.
