Uhm, two things I just don't understand are:
1: What is programming a quantum computer like?
2: What are the useful applications of a quantum computer?
I know everyone always says encryption, which implies that a quantum computer can run calculations in parallel; specifically, significantly more orders of magnitude more parallel than a conventional, multicore / multi-CPU computer.
But beyond that?
- _glass 3y agoI think the first real applications will be, well, simulations of quantum systems. Right now classical supercomputers cannot model complex molecules, but are still better than quantum computers, where you have to take care of the logical qubits they provide. Modelling this can help finding better fertilizer, new drugs, etc.

- potsandpans 3y ago> what is programming a quantum computer like? You compose a series of gates that manipulate the state qbits to perform calculation. My understanding is that these gates can be abstracted in a somewhat familiar programming language environment. I've got a very rudimentary understanding, my crude summary would be: it's basically applied linear algebra, leveraging the properties of superposition to perform some types of computations more efficiently. Namely, reducing some search spaces to sqrt n. This video is a good hands on intro: https://youtu.be/F_Riqjdh2oM https://youtu.be/F_Riqjdh2oM
