The state vector of a pure quantum system is a set of complex probability amplitudes used for describing the system in each state of a given Hilbert space. Characterizing the state of a quantum system is crucial for fundamental studies in quantum mechanics as well as for manipulating and utilizing quantum systems for practical applications.Here we describe a scan-free direct measurement approach [1] that is capable of simultaneously measuring the entire state vector of a pure quantum system…

This Letter presents an interferometric method, in which any qubit state, whether mixed or pure, can be inferred from the visibility, phase shift, and average intensity of an interference pattern using a single-shot measurement, and shows that QSI is more resource efficient than QST for quantification of entanglement in pure bipartite qubits.
