Determining eigenvalues of a density matrix with minimal information in a single experimental setting
Tohru Tanaka, Yukihiro Ota, Mitsunori Kanazawa +3
Eigenvalues of a density matrix characterize well the quantum state's properties, such as coherence and entanglement. We propose a simple method to determine all the eigenvalues of…
