Efficient tests of quantumness implemented on a trapped-ion quantum computer

Presenting Author: Crystal Noel, Duke

A test of quantumness is a protocol where a classical user issues challenges to a quantum device to determine if it exhibits non-classical behavior, under certain cryptographic assumptions. Interactive challenges can be used for tests of quantumness. They require only classical communication and are efficiently verifiable. In this talk, I will show how we implement the first interactive protocol using a trapped ion quantum computer. I will also describe how we execute an efficient non-interactive test of quantumness by modifying the original protocol. Our results significantly exceed the bound for a classical device's success.
