Quantum computing is taking notes from the cloud – recent studies have shown compatibilities between the high-speed, high-security nature of quantum computing calculations and the capabilities of the cloud. Quantum computers, in addition to offering significant speedups for extremely complex computations, are also required to preserve the privacy of the computations they produce. An experiment conducted by scientists and reported in the Science Journal shows how in “blind” quantum computing, inputs can all remain unknown to the computer, through the use of cloud services.
Quantum computing pioneer Anton Zeilinger displayed how quantum computing can be done completely securely within the cloud. In his team’s demonstration, they showed how users send information (single qubits) to a remote computer, along with a formula for the measurements. With crucial data encrypted, the remote computer “entangles” the unknown bits and solves the problem without ever decoding what is actually occurring. Zeilinger’s team built a system to demonstrate how the approach functions, in a series of computational steps that shows the potential for the cloud/quantum computing future. It’s just one more step for the cloud, and a giant leap for mankind. To read more, visit the BBC.
