Performance of stochastic clocks in the Alternate Ticks Game

Understand

In standard quantum theory, time is not an observable.

• It enters as a parameter in the Schr\"odinger equation, but there is no measurement operator associated to it.
• Nevertheless, one may take an operational viewpoint and regard time as the information one can read from clocks.
• The Alternate Ticks Game, introduced in arXiv:1506.01373, is a completely operational means to quantify the accuracy of time scales generated by clocks.
