Testing Possibilities
An introduction to testing SMM and DTT, following the path from a conceptual claim to a specified observable, a competing explanation, and a reproducible protocol with controlled resources.
Read article →From a model to a discriminating test
Which observations would distinguish the proposal?
A meaningful test begins with a defined preparation, intervention, and readout. The experimental programme asks what a specified SMM/DTT construction predicts after calibration, how errors enter that prediction, and whether a simpler comparison model gives the same result.
The articles develop clock-selection certificates, generation–registration order tests, and differential atomic comparisons. These protocols turn broad ideas about temporal structure into relationships among independently accessible quantities. They also make practical assumptions visible, including preparation access, bandwidth, observation windows, response calibration, and the treatment of incomplete or rejected outcomes.
A proposed signal becomes distinctive only when it separates the source model from its relevant alternatives. Ordinary quantum coherence can reproduce some registration effects, while common spectral ratios can test a Coulomb baseline without selecting 137. The programme therefore emphasises fixed parameters, complete outcome statistics, and withheld comparisons rather than fitting a separate explanation to each residual.
Calibrate before comparing
Define the clock or response independently, retain its uncertainty, and freeze the model parameters before evaluating an observable intended as a test.
Measure complete protocols
Keep accepted, rejected, and incomplete outcomes, and include preparation, measurement backaction, and finite observation windows in the predicted distribution rather than only successful averages.
Use strong comparisons
Compare with ordinary quantum-control and atomic baselines, then seek multiple linked observables that cannot all be reproduced by one independently adjusted nuisance parameter.

All 220 articles →Calibrating a clock with finitely many tests
Introduce the finite-calibration converse under an independently bounded generator bandwidth. Explain what a finite sequence of delayed measurements can certify and which prior bound it needs.
Read article →Short clock windows and poor conditioning
Use the draft’s qubit readouts to explain why very short observation windows can make clock calibration unstable. Precision depends on how distinguishable the tested responses are.
Read article →A phase-sensitive registration experiment
Outline the proposed protocol linking source coherence to later completion statistics. Compare its response matrix and energy diagnostic with a simpler qubit baseline.
Read article →Freeze parameters before predicting spectroscopy
Explain the post-freeze strategy proposed for atomic observables. A spectroscopy comparison becomes informative when its coefficients are fixed without using the same transitions as targets.
Read article →Differential spectroscopy as a test strategy
Explain why differences between transitions can test a shared model more strongly than a single fitted line. Develop the proposed holonomy comparison as an overconstrained protocol.
Read article →Designing an overconstrained atomic test
Turn the skeleton draft’s research direction into a practical analysis plan. Require more independent observables than fitted parameters and predeclare the cross-state prediction rules.
Read article →How a protocol can reveal dual-time structure
Outline ways to move beyond the finite prepared linear interface: protocol-dependent access, noncommuting transport, or richer memory. Each route must be defined as an observable procedure.
