In science:

The overall shifts should still be reduced because our single-quantum-jump spectroscopy only needs to excite to the n = 1 state less than 20% of the time.

In order to describe such a dynamics, one has hence to define appropriate stochastic increments (if the monitoring is continuous) or ‘quantum jumps’ [12, 13].

Feedback control in quantum optics: an overview of experimental breakthroughs and areas of application
The observation of Floquet resonance for microobjects in quickly oscillating external fields might bring a new information about the time scale of hypothetical quantum jumps.
Are there Floquet Quanta?
In turn, the appearence of the sharply defined ’Floquet lines’ would confirm the existence of ’slow absorption’ correcting the ideas about quantum jumps .
Are there Floquet Quanta?
We define a quantum measurement as a sequence of binary quantum jumps caused by a macroscopic apparatus. A dynamical theory of measurement is developed, the role of gravity and cosmology being emphasized.
Indeterministic Quantum Gravity and Cosmology XI. Quantum Measurement
As for a critical part, we restrict our consideration to three aspects of the problem of quantum measurements and quantum jumps in general: energy conservation, decoherence, and nonlocality.
Indeterministic Quantum Gravity and Cosmology XI. Quantum Measurement
We treat a quantum measurement in the light of quantum jump dynamics developed in this series of papers [1-10].
Indeterministic Quantum Gravity and Cosmology XI. Quantum Measurement
The impossibility of such a device imposes essential restrictions on measurements and quantum jumps in general.
Indeterministic Quantum Gravity and Cosmology XI. Quantum Measurement
Therefore a theory of measurement and quantum jumps in general must not be based on the concept of decoherence.
Indeterministic Quantum Gravity and Cosmology XI. Quantum Measurement
Quantum entanglement makes possible a situation where a local measurement results in a nonlocal quantum jump.
Indeterministic Quantum Gravity and Cosmology XI. Quantum Measurement
Thus the issue of the relationship between quantum jumps and relativity theory arises.
Indeterministic Quantum Gravity and Cosmology XI. Quantum Measurement
We define a quantum measurement as a sequence of binary quantum jumps caused by a macroscopic apparatus.
Indeterministic Quantum Gravity and Cosmology XI. Quantum Measurement
In view of the principle of cosmic energy determinacy , the law of conservation of energy holds at quantum jumps, so that there is no perpetuum mobile.
