Latest research published in a Science issue by Vienna Center for Quantum Science and Technology (VCQ) at the University of Vienna and the Institute for Quantum Optics and Quantum Information (IQOQI) has demonstrated that cloud computing can deliver secure cloud computation and ensure data privacy.
The publication says that, “Researchers have succeeded in combining the power of quantum computing with the security of quantum cryptography and have shown that perfectly secure
cloud computing can be achieved using the principles of quantum mechanics.” The ‘secure’ feature that cloud computing can acquire through ‘blind
quantum computing’ is exciting to several sectors like healthcare IT, business IT as the constant restraint has been the high-security risks that exist in pure as well as hybrid cloud computing solutions.
Stefanie Barz, the lead author of the study says,” it is conceivable that future quantum computing capabilities will exist only in a few specialised facilities around the world – much like today's supercomputers. Users would then interact with those specialised facilities in order to outsource their quantum computations. The scenario follows the current trend of cloud computing: central remote servers are used to store and process data – everything is done in the "cloud." The obvious challenge is to make globalised computing safe and ensure that users' data stays private.”
Cloud computing will soon have the “newly established fundamental advantage of quantum computers enables the delegation of a quantum computation from a user who does not hold any quantum computational power to a quantum server, while guaranteeing that the user's data remain perfectly private.”
