Quantum drums could lead to more powerful computer networks


Tiny musical instruments could simply be the key to the future of quantum computing. Gizmodo reports that NIST researchers built two tiny (about the width of human hair), quantum intanguated aluminum drums to measure their properties and lay the foundation for large quantum networks.

The team used a microwave light to give the battery two patterns (a “cold and calm”, “the other less stable) that incur that accurate levels that human instruments could not correspond to their level coordination. The scientists then measured tiny differences in the positions of the drum head and found that they would move at the same speed relative to the other, just in different directions.

NIST could only keep the entanglement active for about 200 microseconds, even in the absolute null temperature necessary for the experiment. However, this would be long enough for them to be used as qubits to store data and convert it to and from microwaves that can be sent to distant quantum computers in a network. Other researchers have already tried this before, but they have not had success with an entanglement on demand like this.

There is still a lot of work to stay before it reaches the material outside a laboratory. The research group would like drums to carry out complex operations. The breakthrough suggests that it is just a matter of time, however, and the practical quantum networking could be as close to closer.
