+8. **Claude Shannon (1948)**  
+   * Although Shannon is primarily known for classical information theory, his definition of entropy plays a crucial role in both quantum computing and quantum information theory. Shannon's entropy measures the uncertainty of a random variable, and this concept extends to quantum systems, forming the foundation for quantum information theory.
