"Why you might trust a quantum computer with secrets, even over the internet"

Researchers in Singapore and Australia have discovered a technique that could allow data, calculations, and programs being ran by a user to be hidden from the quantum computer, of which the user is operating over the internet. The technique designed by researchers, includes the preparation of the quantum computer by placing its qubits into a particular form of entangled state, which the qubits are then measured one by one to perform the calculation with step-wise instructions provided by the user for each measurement. These instructions encrypt input data and the program being used. This is a remarkable discovery as earlier hypotheses suggest that such encryption of quantum computation is impossible. This article further discusses this method and how it contributes to security, as well as other developments in quantum computing technology.
