 ==Functionality Description==
-Quantum process tomography is a method used to characterize a physical process in an open quantum system. This method deals with identifying an unknown quantum dynamical process. This is similar to [[State Tomography]] but the goal here is to characterize a quantum gate instead of a state. The figure of merit here is the density matrix of the quantum dynamic process. This method is extremely resource-intensive.
+Quantum process tomography is a method used to characterize a physical process in an open quantum system. A quantum process is a linear super operator which acts on a quantum state to produce another output quantum state. This method deals with identifying this unknown quantum dynamical process. This is similar to [[State Tomography]] but the goal here is to characterize a quantum gate instead of a state. The figure of merit here is the density matrix of the quantum dynamic process.
