I have this code to do a partial measurement on a 2-qubit system.

s=QuantumState["00"]/Sqrt[2]+QuantumState["01"]/Sqrt[6]+QuantumState["10"]I/Sqrt[6]+QuantumState["11"]/Sqrt[6];
s["Formula"]
(* measuring bit[1]*)
qmo=QuantumMeasurementOperator["ComputationalBasis",{1}];
qmo[s]["Probabilities"]
#["Formula"]&/@qmo[s]["StateAssociation"]

The issue is that the returned post-measurement states are not normalized. I'd appreciate it if anyone can let me know how to get the normalized states. Thank you!
