Long-distance quantum links could work by 2030
Boffins working at IBM and Cisco reckon they can link quantum computers over serious distances, and they want to show it is doable before the end of 2030.
The plan could usher in a quantum internet run entirely by potentially dead or alive cats. However, both admitted the networks depend on technologies that do not yet exist and will need universities and federal labs to knock them into shape.
Quantum machines promise to crack physics, chemistry and security problems that would take conventional computers thousands of years. However, they remain error-prone nightmares, and building a dependable model is still a slog for IBM, Alphabet’s Google and the rest. IBM hopes to have an operational machine by 2029.
Cisco opened a lab earlier this year to investigate ways of wiring these chilly contraptions together. The problem starts with IBM’s quantum gear sitting inside huge cryogenic tanks so cold the atoms barely twitch….
