Measurement of energy levels in a quantum clock requires much more energy than its running.

“Researchers found that measuring a quantum clock consumes vastly more energy than the clock’s own operation—up to a billion times more. Scientists learned that reading a quantum clock requires orders of magnitude more energy than running it. This surprising imbalance reveals that observation itself shapes the flow and thermodynamics of time.

The energy cost in quantum timekeeping is. An interesting thing. The requirement for successful quantum technology is the ability to measure energy levels in quantum structures. The quantum-size clocks are required. If we want to make atomic-sized microchips. In those microchips, transistors can involve only three atoms. And those three atoms can form the emitter, base, and collector. If those atomic-size structures are possible. 

That is the revolution in technology. But those systems require quantum-sized clocks that synchronize their operations. The quantum-sized. Or nanosized microchips are similar things. As the so-called regular microchips. Their size is just smaller. They also require very accurate clocks. Quantum clocks can also be used. In the new types of pocket-sized inertial navigation systems. The system must only  measure the beginning position and the speed of the actor. 

The gyroscope registers the changes in direction. And the system uses a clock to measure the distance. Of the traveling. The system calculates the speed and the time. The actor uses the (s=vt) (Journey = speed*time) formula to calculate the journey, or the vector between two waypoints. The system can handle.  Even hundreds of waypoints. That gives inertia high accuracy.

The inertia determines the beginning point and measures the speed. And the simplest way to make that kind of measurement. If the speed changes. Is to determine the.New beginning point . Every time the speed and direction change. 

This system makes it possible. To create a GPS-free system that is impossible to jam. The problem with those systems is that clocks and gyroscopes should be small enough. The system should involve at least two gyroscopes. When the actor changes direction. The system switches the gyroscope and starts the new measurement series. The system requires a speed meter that can be a radar. Or a laser-based system . That allows users to use this inertial even while walking.
