> An analog computer or analogue computer is a type of computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved. In contrast, digital computers represent varying quantities symbolically and by discrete values of both time and amplitude.
- Koshkin 6y agoIsn't a quantum computer digital? ("Quantum" and "continuously changeable" sound opposite to each other.)
- pera 6y agoYes but I don't understand how this can be seen as modelling anything but the experiment one is performing: the way I interpret this proof of quantum supremacy is (and again I know this is incorrect but don't know why) almost like selecting any physical phenomena to which a simulation of it is computationally hard, and then say that the result of this experiment is the returned value of a "computation". I feel it's almost like claiming you are going to simulate fluid dynamics with an actual water tank, some dye, and a camera.
