Experimental quantum advantage with quantum coupon collector. (arXiv:2112.07884v2 [quant-ph] UPDATED)

An increasing number of communication and computational schemes with quantum
advantages have recently been proposed, which implies that quantum technology
has fertile application prospects. However, demonstrating these schemes
experimentally continues to be a central challenge because of the difficulty in
preparing high-dimensional states or highly entangled states. In this study, we
introduce and analyse a quantum coupon collector protocol by employing coherent
states and simple linear optical elements, which was successfully demonstrated
using realistic experimental equipment. We showed that our …
