The trapping problem does not affect the quantum computer. It must not halt for beginning the new task.

The trapping problem does not affect the quantum computer. It must not halt for beginning the new task. Halting one layer or state of the qubit is enough. 

The "trapping problem" means the computer must halt before it can start the new computing process. The regular computer has only a data handling layer with two states zero and one, and when it would need the entire layer or its capacity for making calculations. When some calculation or computing data will send to the system. The system's entire capacity is reserved for the single operand because all data travels like in the one electric wire. 

We can think the computers as factories. Their work is to intake data and process it to the new form. The regular computer has only one line, that handles data. If that system is stuck with some problem, there is no help. Because there is no chance to separate stopped computer from the working computer there is no outcoming help for that problem. 

The only way to tell that something is wrong is to program the computer for reporting to other systems that the work is doing fine. In that case, the program or problem that is driven to the system is segmented into pieces. And the control system will put the recognition mark between the data segments. Those control bites will send the serial number of the work and the individual number of the control segment of the data row to the control system. 

The control system sees that if the same row is running in the system too many times, the control system orders it to stop. In the regular 0/1 computer, the system can do only one mission at a time. Without a control algorithm, the system must search the time what the system uses for a certain operation. And if that time is too long, the system can turn the data row into the garbage. 

But the quantum computers have multiple layers and multiple lines for handling the data. Every single state of the qubit is like a floor in the factory.

And that means the system has multiple data handling lines. That denies the system to stuck in normal cases. The other layer will come for help if another is stuck with the problems like the accurate value of π (3,14.....). There is the possibility that the entire quantum computer can be stuck in this kind of thing like the accurate value of π is taken to every line, and there is no free layer or floor for helping the busy layers.

But the problem can solve by reserving one layer for the control layer, which will unpack the problem if other layers are busy. The quantum system can be stuck in the case that it has the order to increase the power in the data handling process if one layer is not enough. 

If the data travels around one layer and the answer is not satisfying the quantum computer will call another layer to assist with the problem until the entire capacity of the quantum computer is in use. This means that one layer must be kept free for this kind of over leak. 

The term "over-leak" means that the system uses more and more resources for handling some problems and no system has endless resources. Sooner or later that problem is filling the entire system. And that problem reserves all systems resources for a mission that might be endless. So the computer must recognize the endless problems avoiding the over-leak situation.

When we think about the model of the regular computer and intake of the mission. The system works like some factory. There is only one door for intake merchandise. And only one line for handling that merchandise. Before the new mission can take in the system must halt. And the previous mission must take out from the line. 

But when the quantum computer takes the job or the task it must not halt. The thing that is enough is that one layer or state in its qubit is ready. So if we are compiling quantum computers with a factory there are many floors and doors, where the merchandise can take in. So for starting the new mission the entire factory must not stop. The needed thing is that one floor or layer is ready for taking the mission. 

And that means quantum computers can take works more flexibly than regular computers. And if one data handling layer is stuck for working with the problems like π that would not reserve the entire capacity of the data handling system.

If there is happening something unexpected like describe the needed accuracy for the endless decimal numbers. The other layer can ask for help. It can ask other computers do they have a description of how many decimal numbers they are using with endless decimal numbers. Or it can inform the users that they must tell the machine the length of the endless decimal numbers.
