Witnessing negativity of Wigner function by estimating fidelities of cat-like states from homodyne measurements
Jaromir Fiurasek, Miroslav Jezek
We derive sampling functions for estimation of quantum state fidelity with Schrödinger cat-like states, which are defined as superpositions of two coherent states with opposite amp…

Efficient experimental estimation of fidelity of linear optical quantum Toffoli gate
Michal Micuda, Michal Sedlak, Ivo Straka +4
We propose an efficiently measurable lower bound on quantum process fidelity of N-qubit controlled-Z gates. This bound is determined by average output state fidelities for N partia…
