Finite-size Entanglement Certification via Third-Order Local Randomized Measurements
Giovanni Scala, Corrado Cosimo Mattiacci, Dorota Pietryka +1
Certifying entanglement in high-dimensional systems usually requires full state tomography, whose cost grows rapidly with the system dimension. Local randomized measurements offer…
Third-Order Local Randomized Measurements for Finite-size Entanglement Certification
Giovanni Scala, Gniewomir Sarbicki
Randomized measurements access nonlinear functionals without full tomography, yet turning third-order local single-copy data into a strong entanglement test remains difficult. We c…
Optimization of two-photon excitation by indistinguishable photons in a three-level atom
Masood Valipour, Gniewomir Sarbicki, Karolina Słowik +1
We investigate the excitation of a three-level ladder-type atom by a unidirectional field with a pair of indistinguishable photons. Starting from an analytical expression for the t…
Entanglement detection via third-order local invariants from randomized measurements
Giovanni Scala, Anindita Bera, Gniewomir Sarbicki
We compute all third-order local invariants accessible via randomised measurements and employ them to derive separability criteria. The reconstruction of the invariants yields expe…
Optimization of two-photon absorption for three-level atom
Masood Valipour, Gniewomir Sarbicki, Karolina Słowik +1
This work discusses the problem of optimal excitation of a three-level atom of ladder-configuration by light in the two-photon state and coherent light carrying an average of two p…
Quantum trajectories and output field properties for two-photon input field
Anita Dabrowska, Gniewomir Sarbicki
The excitation of atomic and molecular systems by propagating light in a two-photon state within the Wigner-Weisskopf approximation has been described using stochastic tools. The p…
