The article for today.

"Contrary to a classical bit that can only be in the state corresponding to 0 or the state corresponding to 1, a qubit may be in a superposition of both states." from the article for today, https://en.wikipedia.org/wiki/Quantum_superposition as of 2020-05-30.

And super qubit here in sense that it can have more than 3 states: 0, 1 and both in 0 and 1. The super qubit with 4 or more base states.

And the super quantum superposition in the sense that more than 2, 3 positions can be in provision by such super qubit.

And then when I ask in java 


//to obtain a random number between [0 - 2].
int n = new java.util.Random().nextInt(3);
it is looking like a measurement of the classical qubit. For example, http://thetechawesomeness.ideasmatter.info/qubit-measurer-logic-machine.html.

And then when I ask in java


//to obtain a random number between [0 - 3].
int n = new java.util.Random().nextInt(4);

It is looking like a measurement of a super qubit with 4 base states.

Of course it is possible to be obtainable by some combination of several classical qubits.

So by doing those operations it starts to seem that the some randomeness is as inverse of super quantum superposition via super qubits or of some combination of classical qubits.

The more the super qubit has such base states or the combination of qubits, the more the some randomness possibility of such system during measurement.

As from https://stackoverflow.com/questions/5819638/is-random-class-thread-safe as of 2020-05-30 "Is it valid to share one instance of the Random class between multiple threads? It is thread safe in the sense it will still generate random numbers when used by multiple threads. guarantee has been added in the Java 7 documentation: "Instances of java.util.Random are threadsafe."docs.oracle.com/javase/7/docs/api/java/util/Random.html". However, I do not hold the information whether one qubit is measurable by several measuring instruments simultaneosly, synchonously, asynchronously, moreover, whether one super qubit is looking like to provide a prospect for such possibility. And otherwise whether one measuring instrument is providing the possibility to measure several qubits, super qubits or combination of qubits at once, simultaneosly, synchonously, asynchronously.
