DESCRIPTION:A cloud quantum computer is similar to a random number generat
or in that its physical mechanism is inaccessible to the users. In this re
spect\, a cloud quantum computer is a black box. In both devices\, the use
rs decide the device condition from the output. A framework to achieve thi
s exists in the field of random number generation in the form of statistic
al tests for random number generators. In the present study\, we generated
random numbers on the 20-qubit cloud quantum computer and evaluated the c
ondition and stability of its qubits using statistical tests for random nu
mber generators. As a result\, we observed that the qubits varied in bias
and stability. Statistical tests for random number generators may provide
a simple indicator of qubit condition and stability\, enabling users to de
cide for themselves which qubits inside a cloud quantum computer to use.\n
