Quantum computers have not yet achieved any practical application. What they have achieved is performing highly specialized tasks like random circuit sampling or quantum simulation which would be too difficult for even the largest classical computers. While these tasks are highly tailored to the machines and effectively useless in the real world, they are exciting as they are demonstration that these devices can perform computations beyond classical. Turning this computing power towards practical use-cases is more challenging, but something we are likely to see in the next few years. The first applications will likely be ones like quantum chemistry where the problem is inherently quantum mechanical and thus maps more naturally to a quantum computer, or quantum-enhanced classical algorithms which lean heavily on classical solvers combined with quantum. The most important quantum algorithms require error-corrected qubits, which are some ways away but current devices are starting to demonstrate this at a small scale.

- golol 3y agoCould one say that they are basically performing certain physical experiments with particles, and obtaining measurements which would be extremely hard to obtain via classical simulations? Or is that a mischaracterization?
- ghaff 3y agoNot really wrong but using quantum effects to basically model real-world quantum systems is only a subset of potential applications.

- bee_rider 3y agoQuantum computing seems very special-case. I wonder if it is sucking up all the oxygen in the room for “quantum” and “computing” in a sentence together. Classical computing that uses quantum effects seems more useful IMO. Quantum computing algorithms are too hard, let’s do quantum dot cellular automata instead.
