Digital computers have transformed human contact, employment, and time management, yet they have limits in drug development. Classical computers can only hold one piece of data at a time, making it impossible to replicate complicated chemical and biological processes. In contrast, quantum computing constructs physical theories with particles such as electrons or photons. Despite these limits, digital computers continue to play an important role when paired with AI, machine learning, and quantum computing. Digital Twin Systems (DTS) are more extensive and integrated uses of digital twin technology that include entire systems or networks rather than just one physical object. This paper compares various DTS and highlights challenges with those DTS.
