New advances promise secure quantum computing at home -- phys.org [View all]

This is basically describing a technology that would allow people to control their own data while using computing power in the cloud. Currently we are required to upload (albeit perhaps invisibly) our information to the cloud for processing. This includes personal information (PII, PHI), financials, documents, etc.

The full power of next-generation quantum computing could soon be harnessed by millions of individuals and companies, thanks to a breakthrough by scientists at Oxford University Physics guaranteeing security and privacy. This advance promises to unlock the transformative potential of cloud-based quantum computing and is detailed in a new study published in Physical Review Letters. The paper is titled "Verifiable blind quantum computing with trapped ions and single photons."

Quantum computing is developing rapidly, paving the way for new applications that could transform services in many areas like health care and financial services. It works in a fundamentally different way than conventional computing and is potentially far more powerful. However, it currently requires controlled conditions to remain stable and there are concerns around data authenticity and the effectiveness of current security and encryption systems.

"Never in history have the issues surrounding privacy of data and code been more urgently debated than in the present era of cloud computing and artificial intelligence," said Professor David Lucas. "As quantum computers become more capable, people will seek to use them with complete security and privacy over networks, and our new results mark a step change in capability in this respect."

The results could ultimately lead to commercial development of devices to plug into laptops, to safeguard data when people are using quantum cloud computing services.
