Quantum memory study sharpens estimates of closely spaced frequencies
A May paper reports improved precision against direct intensity measurement, with published analysis material available for scrutiny.
Calibration, baselines, and deployment constraints.
A May paper reports improved precision against direct intensity measurement, with published analysis material available for scrutiny.
Recent work on Rydberg readout, quantum memory and optical-clock comparisons shows why the final measurement depends on the whole experiment.
An outdoor result can demonstrate a defined measurement task; it does not validate every claimed underground or navigation application.
