Abstract
Due to the limited availability of quantum computing power in the near future, cryptographic security techniques must be developed for secure remote use of current and future quantum computing hardware. Prominent among these is Universal Blind Quantum Computation (UBQC) and its variations such as Quantum Fully Homomorphic Encryption (QFHE), which herald interactive and remote secure quantum computing power becoming available to parties that require little more than the ability to prepare and measure single qubits. Here I present a simulation of such a protocol, tested classically on the simulation platform LIQ$Ui|\rangle$ and then later adapted to and run on the recently released IBM 16-qubit quantum chip using their beta cloud service. It demonstrates the functionality of the protocol and explores the effects of noise on potential physical systems that would be used to implement it.
