Local qubit invariants on quantum computer
arXiv:2604.15920 · doi:10.1088/1402-4896/ae96dd
Abstract
We present two general methods to implement quantum circuits for the direct measuring of local unitary invariants on quantum computers. We work these out for important three-qubit invariants, and also demonstrate these on the IBM Quantum Platform for important entanglement measures of three qubits.
