Michio Kaku "Moore's law and Quantum Computers"

Michio Kaku “Moore’s law and Computers”

Welcome to our blog. Some days ago in the NTYCX class our teacher showed us a very interesting video of Michio Kaku, a really recognized physicist, https://youtu.be/rUWfod_8JsM. The main topic was ''How to program a Quantum Computer''.
Also in this video there are explanations about technology. Before you watch this video, you have to know that some words are difficult to understand so probably you will need a dictionary.

Michio Kaku, the theoretical physicist, starts the video explaining about the Moore's law (you can see the definition in the green box). Michio says that this will colapse giving a nice example " if you know that in christmas time you will get the same computer of last year, would you buy it if it is exactly the same?" The answer is probably no. It is expected a big economic depression because the people will not buy new computers.

This makes us wonder, how will the computers be in te future?

Quantum computers

Probably the replacement of sylicon power will be quantum computers, but we don't know when this will happen.

quantum computers require totally different way of programming. This type of computers consist on individual atoms instead of numbers.
The source of the power of quantum computers are quantum bits. You are no lo longer calculating on numbers, but how do you programm them? 3 x 5 = 15 is the world's record for QC calculations. This may seem easy, but it is not, it is really difficult to build and programm.
Stability and decoherence is the big issue. Every simple movement causes decoherence making it useless.

Computer architecture

Computer architecture is a set of rules and methods that describe the functionality, organization, and implementation of computer systems. Examples, Microprossesers, personal computers, microcontroler.

Computer architecture normally consists in three elements, ISA, Microarchitecture and Harware components, which are optional.

ISA 

•  Analogous to human language
•  Allows communication between H/W ans S/W
• Collection of comands

Microarchitecture

• Interconnection technique between different elements of the mashine
• It defines data paths, dataprocessing and storage element

Harware components (optional)

• System design, performances and cost flexibility
• Example: Ram, imput and output ports

We hope you like our post, here you can watch the explenation of  Michio Kaku about quantum computers.
