Counterfactual generation of cat states
Akshata Shenoy H., R. Srikanth · arXiv (Cornell University) · 2015
In the counterfactual cryptography scheme proposed by Noh (2009), the sender Alice probabilistically transmits classical information to the receiver Bob without the physical travel of a particle. Here we generalize this idea to the transmission of quantum information. The key insight is to replace their classical input choices with quantum superpositions. We further show that the scheme can be generalized to counterfactually generate multi-partite cat states.
