But that begs the question of how we know that we have produced an entangled pair. Do we not need a metric to use to make sure they are entangled?

- stelfer 6y agoThe act of measurement on the second particle destroys the entagled state of the pair. That effect can be measured on the first particle's side (which may be far away... on the other side of the galaxy maybe).
- jiofih 6y agoBut to see/interpret the effect on the first particle, you need to know what the measurement on the second was, and that information needs to be transferred across the galaxy by conventional means. Honesty quantum mechanics sounds more like a bug in the universe or some quirk we just don’t understand yet.
- jaggirs 6y agoYour question boils down to whether or not the quantum circuit that entangles the qubits works correctly. You can simply test the reliability of the quantum circuit by running it multiple times and checking that the outcomes behave as you expect. For example, if your circuit is supposed to generate the entagled pair [00 or 11 with equal probability] you would expect measurements to either be 00 or 11 and never 01 or 10.
