How to get the group of qubits which are on the same port of measurement?
From IBMQ's quantum computer, we know that logical qubits are mapped to their computers' physical qubits, and then they are measured to get classical bits (0 and 1). For instance, a 27-qubit ...

Dose Quantum threshold theorem apply to IBM Quantum Experience
According to Quantum threshold theorem, error rate can be arbitrarily low. But when I use IBM Quantum Experience to measure a simple $|+\rangle$, it gives result of $|1\rangle$ with probability of 52....
