Quantum Computing Research: Math & Mechanics Needed?

Click For Summary
SUMMARY

Research in quantum computing, particularly in algorithms and theoretical computer science, requires a foundational understanding of quantum mechanics. A standard undergraduate level of quantum mechanics, such as that covered in David Griffiths' textbook, is sufficient for many theoretical aspects. However, familiarity with quantum field theory may enhance understanding, especially for advanced topics. Theoretical computer scientists in quantum computing typically reference "Quantum Computation and Quantum Information" by Nielsen and Chuang for a comprehensive grasp of the necessary quantum mechanics.

PREREQUISITES
  • Understanding of quantum mechanics at the undergraduate level (Griffiths)
  • Familiarity with quantum computation principles (Nielsen and Chuang)
  • Basic knowledge of theoretical computer science
  • Mathematical proficiency in linear algebra and complex numbers
NEXT STEPS
  • Study "Quantum Computation and Quantum Information" by Nielsen and Chuang
  • Explore advanced topics in quantum mechanics, including quantum field theory
  • Research topological quantum computing and its mathematical foundations
  • Investigate algorithms specific to quantum computing
USEFUL FOR

This discussion is beneficial for aspiring quantum computing researchers, theoretical computer scientists, and applied mathematicians interested in the mathematical and algorithmic aspects of quantum mechanics.

I'm interested in doing research in quantum computing. By that I mainly mean the algorithms and theoretical computer science part, not the experimental part. How much quantum mechanics do I need to know for that? Is the standard undergraduate Griffiths level enough? Do I need to know quantum field theory? What kind of math should I study for that? Is topological quantum computing something an applied mathematician should study or is it just pure mathematics?

Hey ehrenfest. I really don't know how much QM you'd need to know to work in theory but I do work as an internin an Exp Quantum computing lab. I have a griffiths level education in quantum and I am able to get by. a lot still goes over my head though.
 
The TCS people in quantum computing generally know as much QM as you can get out of the Nielsen and Chuang book.
