Minimal orthonormal bases for pure quantum state estimation
Authors: Zambrano, Leonardo; Pereira, Luciano; Delgado, Aldo Journal: QUANTUM Publication date: 2024/02/08 DOI: Abstract: We present an analytical method to estimate pure quantum states using a minimum of three measurement bases in any finite -dimensional Hilbert space. This is optimal as two bases are insufficient to construct an informationally complete positive operator -valued measurement (ICPOVM) [...]
