Understanding Quantum Computing: From Qubits to Programming

This chapter explores the fundamental differences between classical and quantum computing, focusing on the unique functionalities of qubits and their potential for high-precision calculations. It delves into the concepts of logical versus physical qubits, error correction, and various computational models, including gate model and quantum annealing systems. Additionally, the discussion sheds light on the intricacies of programming for quantum computers, particularly with Rigetti systems, and how it diverges from classical programming techniques.
