- krastanov 5y agoToday's quantum "computers" are not big or reliable enough to perform "scalable quantum computation" which is the promise of solving some very particular problems exponentially faster than classical computers. However, they are now sufficiently versatile to showcase demos in which they work as analog computers, mimicking very complex states of matter that are otherwise difficult to prepare in a lab or study in classical simulations. It is not particularly practical yet, but it is a convenient benchmark of versatility and "quantumness" on the way to trully scalable universal quantum computers. Think of it as a cool demo of some small part of the required functionality. I imagine demos like this one will one day be part of a benchmark suite for the low-level hardware of a complete quantum computer.
