Oxford’s Secure Quantum Computing Breakthrough

Researchers at Oxford University’s UK Quantum Computing and Simulation Hub claim to have made what could be an important breakthrough in quantum computing security. 

The Issue 

As things stand, if businesses want to use cloud-based quantum computing services, they face privacy and security issues when trying to do so over a network, similar to the issues in traditional cloud computing. For example, users can’t keep their work secret from the server or check their results on their own when tasks get too complex for classical simulations, i.e. they risk disclosing sensitive information like the results of the computation or even the algorithm used itself.
