Entangling macroscopic light states by delocalized photon addition
Nicola Biagi, Luca S. Costanzo, Marco Bellini +1
We present the experimental generation of tunable entanglement between distinct field modes by the delocalized addition of a single photon. We show that one can preserve a high deg…
Measurement-induced strong Kerr nonlinearity for weak quantum states of light
Luca S. Costanzo, Antonio S. Coelho, Nicola Biagi +3
Strong nonlinearity at the single photon level represents a crucial enabling tool for optical quantum technologies. Here we report on experimental implementation of a strong Kerr n…
Conditional Hybrid Nonclassicality
E. Agudelo, J. Sperling, L. S. Costanzo +3
We derive and implement a general method to characterize the nonclassicality in compound discrete- and continuous-variable systems. For this purpose, we introduce the operational n…
Zero-area single photon pulses
L. S. Costanzo, A. S. Coelho, D. Pellegrino +6
Broadband single photons are usually considered not to couple efficiently to atomic gases because of the large mismatch in bandwidth. Contrary to this intuitive picture, here we de…
Universal state orthogonalizer and qubit generator
Antonio S. Coelho, Luca S. Costanzo, Alessandro Zavatta +3
The superposition principle is at the heart of quantum mechanics and at the root of many paradoxes arising when trying to extend its predictions to our everyday world. Schroedinger…
Entangling quantum and classical states of light
Hyunseok Jeong, Alessandro Zavatta, Minsu Kang +5
Entanglement between quantum and classical objects is of special interest in the context of fundamental studies of quantum mechanics and potential applications to quantum informati…
