National-security experts and politicians have a message for America: A significant portion of the sensitive data we have today is going to be cracked by foreign powers in the not-too-distant future, and there is nothing anyone can do about it.
But we might be able to stop them from decoding the data we produce down the road, if we act quickly enough.
The danger comes from an ultrapowerful and still-experimental technology called quantum computing—which leverages the quantum properties of atoms to quickly compute problems that no conventional computer could crack. China has already launched the equivalent of a Manhattan Project in order to achieve this end, say experts, and companies like Google, Microsoft and IBM are all pushing ahead with their own efforts to create quantum computers.
Quantum computers, which are still in the very early stage, could revolutionize any number of real-world tasks, from researching new materials to picking the best route for delivery drivers. But right now, what many experts worry about is the problem of security.
