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…
