1 Aug 2020 | | Abstract: | Quantum Zeno Effect (QZE) has been one of the most interesting phenomena in
quantum mechanics ever since its discovery in 1977 by Misra and Sudarshan [J.
Math. Phys. extbf{18}, 756 (1977)]. There have been many attempts for
experimental realization of the same. Here, we present the first ever
simulation of QZE on IBM quantum experience platform. We simulate a two-level
system for Rabi-driven oscillation and then disturb the time evolution by
intermediate repetitive measurements using quantum gates to increase the
survival probability of the qubit in the initial state. The circuits are
designed along with the added intermediate measurements and executed on IBM
quantum simulator, and the outcomes are shown to be consistent with the
predictions. The increasing survival probability with the number of
intermediate measurements demonstrates QZE. Furthermore, some alternative
explanations for the obtained results are provided which leads to some
ambiguity in giving the exact reasoning for the observed outcomes. | | Source: | arXiv, 2008.01070 | | Services: | Forum | Review | PDF | Favorites | |
