Private quantum computation: An introduction to blind quantum computing and related protocols
It addresses the problem of secure quantum computation for researchers and practitioners in quantum technologies, but is incremental as it is a review of existing work.
The paper reviews protocols that securely delegate quantum computation to untrusted devices, focusing on maintaining privacy and integrity of the computation.
Quantum technologies hold the promise of not only faster algorithmic processing of data, via quantum computation, but also of more secure communications, in the form of quantum cryptography. In recent years, a number of protocols have emerged which seek to marry these concepts for the purpose of securing computation rather than communication. These protocols address the task of securely delegating quantum computation to an untrusted device while maintaining the privacy, and in some instances the integrity, of the computation. We present a review of the progress to date in this emerging area.
