This chapter delves into the basics of quantum computing (QC), tracing the evolution of its theories and technologies. We will explore various business use cases to highlight the practical applications of QC. Additionally, this chapter examines the security threats posed by QC, including the “harvest now, decrypt later” approach and the potential to break asymmetric cryptography. To address these challenges, this chapter discusses QC security and privacy protection solutions, covering regulations, post-quantum cryptography, and preparation strategies for a post-quantum world. This chapter covers the following topics: Quantum Computing Basics Business Use Cases Security threats posed by quantum computing Quantum Computing Security and Privacy Protection Solutions
