Abstract
Entanglement is a key resource in many quantum communication tasks such as quantum cryptography. Inevitable losses in quantum channels degrade entanglement; therefore, practically making entanglement not useful for these tasks. To mitigate loss, different techniques have been proposed, where a noiseless linear amplifier (NLA) is one of them. A crucial aspect of noiseless quantum amplifiers is their probability of success. Thus, optimizing optical noiseless amplifiers and enhancing their success probability within a designated amplification range is a significant objective. In this context, we demonstrate a pioneering experimental protocol, strategically crafted to improve the probability of success of existing NLA protocols.

I am an experimental physicist involved in research in optical quantum information processing. I did my PhD (2015-2019) in Prof. Pryde’s lab at Griffith University (QOIL). I worked on different projects, including quantum simulation of stochastic processes, efficient single-photon sources and quantum non-locality tasks. Then I joined CGG, as an imaging geophysicist, where I worked on seismic image processing from 2019-2021. In 2021, I joined Prof. Pryde’s lab, as part of CQC2T, to work on quantum communications. Currently, I am a GUPF fellow, where I work on the simulation of recursive stochastic processes using quantum machines.
