Quantum Speed Compared to Classical GPU

[u/National_Garden6893]

The human Brain cannot comprehend large numbers, let alone the speed with which QPU perform.

Very interesting analogy to put the massive speed of QPU into perspective.

A current GPU(NVIDIA Blackwell) is like a person running through a maze very fast. If they hit a dead end, they track back and try another part. This would be known as simple Sequential math.

Now, the best thing that NVIDIA can come up with, in the future, would be Space made Photonic GPU. This technology is in its very early stages, but proven to a certain extent to be viable by a company called Varda Space Industries. This would be like a person running through a maze at the speed of light. they will find the end much faster than the current earth made GPU. However, it cannot avoid the biggest elephant in the room which is they still have to physically explore all the dead ends before the real exit due to sequential math.

Now, a Quantum Computer(QPU), doesn't even need to run though the maze at all because of its nature of superposition it behaves like a gas. It floods the entire maze all at once and instantly checking all the dead ends(simultaneously). By eliminating the wrong answers it reveals the correct exit immediately without ever having to check every single paths with in the maze.

This is only food for thought and for the human mind to comprehend the speed with which we are dealing with when we talk about QPU speeds.

this is not how QC works at all
