Measuring the largest coefficients of a quantum state
Nicolás Ciancaglini, Santiago Cifuentes, Guido Bellomo +2
We introduce a hierarchical algorithm for identifying the indices of the largest Pauli coefficients of an unknown -qubit quantum state, either those exceeding a threshold or the…

Towards exact algorithmic proofs of maximal mutually unbiased bases sets in arbitrary integer dimension
Santiago Cifuentes, Nicolás Ciancaglini, Guido Bellomo +2
In this paper, we explore the concept of Mutually Unbiased Bases (MUBs) in discrete quantum systems. It is known that for dimensions that are powers of prime numbers, there exi…
