Book description
Acquire knowledge of quantum chemistry concepts, the postulates of quantum mechanics, and the foundations of quantum computing, and execute illustrations made with Python code, Qiskit, and opensource quantum chemistry packages
Key Features
 Be at the forefront of a quest for increased accuracy in chemistry applications and computing
 Get familiar with some open source quantum chemistry packages to run your own experiments
 Develop awareness of computational chemistry problems by using postulates of quantum mechanics
Book Description
Explore quantum chemical concepts and the postulates of quantum mechanics in a modern fashion, with the intent to see how chemistry and computing intertwine. Along the way you’ll relate these concepts to quantum information theory and computation. We build a framework of computational tools that lead you through traditional computational methods and straight to the forefront of exciting opportunities. These opportunities will rely on achieving nextgeneration accuracy by going further than the standard approximations such as beyond BornOppenheimer calculations.
Discover how leveraging quantum chemistry and computing is a key enabler for overcoming major challenges in the broader chemical industry. The skills that you will learn can be utilized to solve newage business needs that specifically hinge on quantum chemistry
What you will learn
 Understand mathematical properties of the building blocks of matter
 Run through the principles of quantum mechanics with illustrations
 Design quantum gate circuit computations
 Program in opensource chemistry software packages such as Qiskit®
 Execute stateoftheartchemistry calculations and simulations
 Run companion Jupyter notebooks on the cloud with just a web browser
 Explain standard approximations in chemical simulations
Who this book is for
Professionals interested in chemistry and computer science at the early stages of learning, or interested in a career of quantum computational chemistry and quantum computing, including advanced high school and college students. Helpful to have high school level chemistry, mathematics (algebra), and programming. An introductory level of understanding Python is sufficient to read the code presented to illustrate quantum chemistry and computing
