The complete power of next-generation quantum computing could soon be harnessed by thousands and thousands of people and firms, because of a breakthrough by scientists at Oxford University Physics guaranteeing security and privacy. This advance guarantees to unlock the transformative potential of cloud-based quantum computing and is detailed in a brand new study published within the influential U.S. scientific journal Physical Review Letters.
Quantum computing is developing rapidly, paving the best way for brand new applications which could transform services in lots of areas like healthcare and financial services. It really works in a fundamentally different method to conventional computing and is potentially much more powerful. Nevertheless, it currently requires controlled conditions to stay stable and there are concerns around data authenticity and the effectiveness of current security and encryption systems.
Several leading providers of cloud-based services, like Google, Amazon, and IBM, already individually offer some elements of quantum computing. Safeguarding the privacy and security of customer data is an important precursor to scaling up and expending its use, and for the event of latest applications because the technology advances. The brand new study by researchers at Oxford University Physics addresses these challenges.
“We now have shown for the primary time that quantum computing within the cloud will be accessed in a scalable, practical way which may even give people complete security and privacy of information, plus the power to confirm its authenticity,” said Professor David Lucas, who co-heads the Oxford University Physics research team and is lead scientist on the UK Quantum Computing and Simulation Hub, led from Oxford University Physics.
In the brand new study, the researchers use an approach dubbed “blind quantum computing,” which connects two totally separate quantum computing entities — potentially a person at home or in an office accessing a cloud server — in a very secure way. Importantly, their recent methods could possibly be scaled as much as large quantum computations.
“Using blind quantum computing, clients can access distant quantum computers to process confidential data with secret algorithms and even confirm the outcomes are correct, without revealing any useful information. Realising this idea is an enormous step forward in each quantum computing and keeping our information protected online” said study lead Dr Peter Drmota, of Oxford University Physics.
The researchers created a system comprising a fibre network link between a quantum computing server and a straightforward device detecting photons, or particles of sunshine, at an independent computer remotely accessing its cloud services. This enables so-called blind quantum computing over a network. Every computation incurs a correction which should be applied to all that follow and desires real-time information to comply with the algorithm. The researchers used a singular combination of quantum memory and photons to attain this.
“Never in history have the problems surrounding privacy of information and code been more urgently debated than in the current era of cloud computing and artificial intelligence,” said Professor David Lucas. “As quantum computers turn out to be more capable, people will seek to make use of them with complete security and privacy over networks, and our recent results mark a step change in capability on this respect.”
The outcomes could ultimately result in industrial development of devices to plug into laptops, to safeguard data when individuals are using quantum cloud computing services.
Researchers exploring quantum computing and technologies at Oxford University Physics have access to the state-of-the-art Beecroft laboratory facility, specially constructed to create stable and secure conditions including eliminating vibration.
