I'm new to IBM, so I'm still figuring things out. I want to make a POVM measurement of a quantum state for state discrimination purposes. In other words I want a measurement that has three outcomes:
A: It's state A with 100 % certainty (or x %) B: It's state B with 100 % certainty (or x %) C: Can't determine if it's state A or B.
Can anyone help with how to do this in IBM's Quantum Composer?
