My Actifit Report Card: December 17 2024

Google has presented Willow, a chip that can bring quantum computing, finally, one of the most surprising achievements of Willow is its ability to execute tasks in a very short time, they literally say that in 5 minutes it can surpass and do tasks of more advanced classic supercomputers. which would take them 10,000 trillion years, a beast, far exceeding the age of the universe.

It seems that what Google engineers have managed to do is defeat the theory of quantum error correction, a theory formulated by American mathematician and theorist Peter Shor.

Classical computing, which we use in our mobile phones, cell phones, computers, etc., uses bits that can have a value of zero or one while quantum computing uses qubits that can have a value between 0 and 1 or both simultaneously, if you have two. classic bits you can represent four combinations 00 01 10 and 11, but you can only process them sequentially, however with two bytes you can represent those same four combinations at the same time at the same time and also each qubit added to the system doubles the possibilities.

Let's take an example, a classic maze, imagine that you are in the maze and there are hundreds or thousands of potential paths, but only one is the correct one. What would the protagonist of this challenge do? If he had a conventional computer, the computer would analyze each and every one. of the paths until you find the right one, something that can take a long time, but what would you do with a quantum computer, the quantum computer would be as if it were a drone and could stand up and see the entire labyrinth from the air, analyzing all the possibilities at the same time and achieving a much better result fast.

At the moment we do not expect to see it in our homes, it will happen as it did with normal computing initially, the first computers that were huge and very expensive were destined for companies, for military services, obviously for the government, for laboratories so it will surely be 20 or 30 years before that we see quantum computers in our home or at reasonable prices.
