Measuring the largest coefficients of a quantum state
Nicolás Ciancaglini, Santiago Cifuentes, Guido Bellomo +2
We introduce a hierarchical algorithm for identifying the largest Pauli coefficients of an unknown -qubit quantum state. The algorithm traverses a prefix-based tree whose nodes…
Selective continuous-variable quantum process tomography
Virginia Feldman, Ariel Bendersky
Quantum process tomography is a useful tool for characterizing quantum processes. This task is essential for the development of different areas, such as quantum information process…
Selective quantum state tomography for continuous-variable systems
Virginia Feldman, Ariel Bendersky
We present a protocol that allows the estimation of any density matrix element for continuous-variable quantum states, without resorting to the complete reconstruction of the full…
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…
Characterization of non-signaling correlations from mutual information
Ignacio Perito, Guido Bellomo, Daniel Galicer +3
We present a characterization of the set of non-signaling correlations in terms of a two dimensional representation that involves the maximal value of a Bell functional and the mut…
Impossibility of memory in hidden-signaling models for quantum correlations
Ignacio Perito, Guido Bellomo, Daniel Galicer +3
We consider a toy model for non-local quantum correlations in which nature resorts to some form of hidden signaling (i.e., signaling between boxes but not available to the users) t…
