This is a fantastic book for those interested in physics, but more importantly for those interested in change. It is the biography of Richard Feynman, the talented physicist, winner of the Nobel … Read more Prize and major contributor to our understanding of particle physics. The term ‘genius’ is often used cheaply, and although Feynman would have declined the description, having read this account it is difficult to argue that he was not fully deserving of the title.I first became aware of Richard Feynman through quotations credited to him, and was intrigued to find out more about the man behind the ideas. This book deals with his life and achievements and as much of this was directed at the hidden and mysterious world and mathematics that define the inner working of atoms, you might expect a difficult read. Have no fear.
The Bloch sphere is a representation of a qubit , the fundamental building block of quantum computers. A quantum computer is a computation device that makes direct use of quantum mechanical phenomena , such as superposition and entanglement , to perform operations on data . Quantum computers are different from digital computers based on transistors . Whereas digital computers require data to be encoded into binary digits ( bits ), quantum computation uses quantum properties to represent data and perform operations on these data. [ 1 ] A theoretical model is the quantum Turing machine , also known as the universal quantum computer. Quantum computers share theoretical similarities with non-deterministic and probabilistic computers .
Richard Phillips Feynman ( pron.: / ˈ f aɪ n m ən / ; May 11, 1918 – February 15, 1988) [ 2 ] was an American theoretical physicist known for his work in the path integral formulation of quantum mechanics , the theory of quantum electrodynamics , and the physics of the superfluidity of supercooled liquid helium , as well as in particle physics (he proposed the parton model). For his contributions to the development of quantum electrodynamics, Feynman, jointly with Julian Schwinger and Sin-Itiro Tomonaga , received the Nobel Prize in Physics in 1965. He developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles , which later became known as Feynman diagrams . During his lifetime, Feynman became one of the best-known scientists in the world.
