From Classical to Quantum Information Science: Shifts to New Theories, New Applications

Shamba Dutta

Abstract


Information is an idea created in human brain. But information has physical aspects too. Emergence of new theory and technology in physical science always contribute to shape various theories, models and services in LIS. Shannon’s mathematical formula derives strength from the physical aspect of data or information and gives a new information theoretic approach to communication model by introducing concepts of bit and entropy. With the advancement of Quantum mechanics a new quantum mechanical model is under preparation. Phenomenon like quantum entanglement is successfully being used in computer technology which in turn helps reshape many LIS services. Quantum information science is a newly flourishing field which is expected to bring great advancements in information organization, processing, retrieval, automatic classification, NLP and other LIS related problems.
