In the fast-evolving world of quantum computing, one of the biggest hurdles isn’t how fast calculations can be done—it’s how long you can hold onto the delicate quantum information in the first place.

A crucial building block for quantum computers based on sound has been shown to work for the first time. One popular way of building quantum computers is to encode information into quantum states of ...

Some properties of quantum computers can be imitated with sound trapped in a simple mechanical device. This has the advantage of being less fragile than quantum computers, while still replicating some ...
