What this work is, and what it is not

Quantum devices are real, and their present capabilities are narrow. A simulated circuit is not a device; an algorithm with an asymptotic advantage is not an advantage at any size that has been run. Every result from this division states the qubit count, the noise model and the classical baseline it was compared against, and any claim of quantum advantage that omits the classical baseline is treated as unsupported.

Computational research. Computed from established physics. A computed number is a prediction, and it is only as good as its convergence, its error budget, and whatever data it can be checked against.

Scale bands are a research classification, not a claim of experimental reach. Most of this span cannot be probed by any apparatus that exists: nothing below about 10^-19 m has been measured directly, and anything at 10^26 m or beyond is inferred from observation rather than engineered. Every opportunity states the kind of work it actually is.

Charter

This division builds and simulates quantum models, develops algorithms, models devices, and analyses quantum measurements. It benchmarks honestly against classical methods, and it does not describe a simulated device as a built one.
