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.
