Book Description

Build a solid foundation in quantum chemistry and quantum computing using modern tools, updated frameworks, and practical Python examples. In its second edition, this book enhances the original with new chapters and refreshed workflows aligned with the latest advancements. You begin with core principles of quantum mechanics, quantum information, and molecular Hamiltonians, updated to incorporate the latest Qiskit capabilities. You then implement hybrid algorithms such as VQE using improved Python workflows. New to this edition, you will explore noise-aware quantum chemistry, including error-mitigation techniques and optimizer behavior in realistic simulations. The book also introduces quantum machine learning for molecular prediction and a new generation of quantum algorithms for chemistry, including Quantum Phase Estimation (QPE), Quantum Imaginary-Time Evolution (QITE), quantum Lanczos and subspace methods, and sampling-based approaches such as Sample-based Quantum Diagonalization (SQD), Sample-based Krylov Quantum Diagonalization (SKQD), and SqDRIFT, which combines SKQD with a qDRIFT-style randomized compilation of the Hamiltonian propagator. By the end of this book, you will be able to model molecular systems and apply modern quantum techniques with confidence.
