Quantum computing has quickly become at the vanguard of many computer science fields today. This is motivated by quantum computers ability to perform computational tasks with efficiencies that are not possible with classical computers. Quantum computing technology has a lasting potential impact on society and a broad implications on many aspects of our lives. Communications Industry Researchers (CIR) estimates that the global quantum-computing market is expected to reach $1.9 billion in 2023, increasing to $8 billion by 2027, in spending on associated software and services. Although quantum computing has several advantages, it threatens the current cryptographic techniques, which are necessary for today’s Internet standards like the Transport Layer Security (TLS).
