Single-qubit, entanglement-assisted and ancilla-assisted quantum process tomography
Quantum process tomography allows complete and precise characterization of a quantum operation. We report quantum process tomography of unitary, decohering, and partially polarizing operations using single-qubit, maximally entangled, and non-entangled input states.
