Quantum blockchain using weighted hypergraph states
Shreya Banerjee, Arghya Mukherjee, Prasanta K. Panigrahi
Abstract
This paper proposes a protocol to prepare a blockchain using quantum tools which maintains the distributive nature of the blockchain and provides security against a quantum attacker. The authors provide an example of a two blockchain prepared in IBM 5 qubit quantum computer, as a proof of concept with fidelity close to 0.9548.
