# Bell state: simultaneous measurement of two entangled qubits

What will happen if the two qubits in Bell state for a 2-qubit system, $$\frac{1}{\sqrt2}(\left|00\right\rangle+\left|11\right\rangle)$$ are simultaneously measured at the same instant? Two scenarios: Qubits are measured in the same states or different states. Has anyone tried to measure the qubits experimentally in IBM-Q? What is the answer from Quantum Mechanics?

I tried to prepare and measure this Bell state on IBM Q. There is a low probablity, around few percent, that you measure states $$|01\rangle$$ or $$|10\rangle$$. But this is caused by a thermal noise and spontaneous break of the entangled state.
