The Covid Wave

China buckles.

1. Today’s quantum computers are “noisy,” meaning that they fail at almost everything they attempt. Nevertheless, the race to build them has attracted as dense a concentration of genius as any scientific problem on the planet. Intel, I.B.M., Microsoft, and Amazon (along with Google) are also building quantum computers. So is the Chinese government. The winner of the race will produce the successor to the silicon microchip, the device that enabled the information revolution. A full-scale quantum computer could crack our current encryption protocols, essentially breaking the Internet. Most online communications, including financial transactions and popular text-messaging platforms, are protected by cryptographic keys that would take a conventional computer millions of years to decipher. A working quantum computer could presumably crack one in less than a day. That is only the beginning. A quantum computer could open new frontiers in mathematics, revolutionizing our idea of what it means to “compute.” Its processing power could spur the development of new industrial chemicals, addressing the problems of climate change and food scarcity. And it could reconcile the elegant theories of Albert Einstein with the unruly microverse of particle physics, enabling discoveries about space and time. “The impact of quantum computing is going to be more profound than any technology to date,” Jeremy O’Brien, the C.E.O. of the startup PsiQuantum, said recently. First, though, the engineers have to get it to work. (Source: newyorker.com, italics mine)
