This brief post shows how to establish an entangled state on IBM Quantum’s computers – here using ibmq_manila.
The circuit to establish \(\displaystyle \frac{|00\rangle + |11\rangle}{\sqrt{2}}\) is as follows:
A few clicks later, and the circuit is added to the queue…
The total wait to get onto ibmq_manila was about an hour and the circuit ran 1,000 times in 5 seconds.
Here are the results:
It worked across 93.9% of runs: both qubits had the same measurement outcome, roughly 50-50 split between \(|00\rangle\) and \(|11\rangle\).
