Quantum computation vs classic computation

Click For Summary

Discussion Overview

The discussion revolves around the approach to learning quantum computation, particularly for someone with a background in mathematics and computer engineering but limited knowledge of quantum physics. Participants explore whether to start with quantum physics basics or dive directly into quantum computation theory.

Discussion Character

  • Exploratory, Conceptual clarification, Homework-related

Main Points Raised

  • One participant expresses uncertainty about whether to begin with quantum physics or focus on quantum computation theory.
  • Another participant recommends the book "Quantum Computation and Quantum Information" by Nielsen and Chuang, noting it requires no prior knowledge of quantum mechanics and is suitable for beginners.
  • A third participant agrees on the value of the suggested book but cautions that its chapter on physical realizations of quantum computers may be outdated due to advancements in the experimental field.
  • One participant raises the distinction between hardware and software interests, suggesting that if the focus is on software, understanding quantum logic may suffice without delving deeply into quantum mechanics.
  • This participant also mentions that basic quantum mechanics knowledge may be beneficial for those interested in hardware aspects and suggests using resources like YouTube and Wikipedia for foundational understanding.

Areas of Agreement / Disagreement

Participants generally agree on the usefulness of the recommended book for beginners, but there are differing opinions on the necessity of learning quantum mechanics versus focusing on quantum computation theory, indicating multiple competing views.

Contextual Notes

Some participants highlight the potential limitations of the recommended book due to its age and the evolving nature of the experimental field in quantum computing.

Who May Find This Useful

This discussion may be useful for students or individuals interested in transitioning into quantum computation from mathematics or computer engineering backgrounds, particularly those seeking guidance on foundational learning paths.

Next semester I am going to write a undergrad thesis about quantum computation, but my background is not from physics but from mathematics and computer engineering. In this talk http://www.youtube.com/watch?v=Rvn_3cCrl9c Andris Ambainis talks about how he got into the field of quantum computing and suggest that one can learn quantum mechanics by first learning about quantum computers. Is this a good idea?

My problem is this. I want to write about quantum computation (from a abstract computational view), but I don't know any quantum physics. Shall I start by learning the basics of quantum physics or go straight to quantum computation theory?
 
Physics news on Phys.org
I would suggest Quantum Computation and Quantum Information by Nielsen and Chuang. It assumes no prior knowledge in Quantum Mechanics. If you have some experience in Linear Algebra, then it would be a bonus.Welcome to Physics Forums.

The book suggested above is very good. It has a lot of material for the beginner and they describe the basics very thouroughly. Just be aware that the chapter on the physical realization of quantum computers is somewhat outdated by now as the book is more than 10 years old and the experimental field has moved forward a lot since then. For the rest though, the book is a very good starting place.
 
I would ask myself, hardware or software? If you are only interested in the software side, focus on the quantum logic (I'd ignorantly say it's like fuzzy logic). I don't think actual quantum mechanics is important. However if you do have an interest in the hardware side, some basic quantum mechanics on the experimental side (which is easier) would do. I am not a quantum computer expert. I am just a quantum physicist. Theoretical quantum physics can be tricky with the bra ket notation and all the other conventions. So just avoid that. I would just use youtube and Wikipedia for a basic overview. It's silly, but that helped me so much. Good luck and please post a link when you are done writing!
