... where Iˆ is the identity operator defined in the first problem. (e) If T̂L f (x) = f (x − L), how does T̂L act of f˜(k), the fourier transform of f (x)? In other words, what modification of f˜(k) corresponds to translating f (x) by L? (f) Use parts (c) and (e) to determine how D̂ acts on f˜(k). (g) ...

a simple explanation of search technique in quantum framework
... telephone number of a person is the key instead of his name and we want to find the name of the person. In this case binary search is not possible to search this unsorted data base. The major drawback of binary search is the sorting then searching .In real world we have certain problems which have t ...

Extending the idea to real-world applications, Wiesner believed that if money were encoded by these quantum systems ...

Bohr`s atomic model: the evolution of a theory
... Others didn’t think there were such elements at all, they held matter to be infinitely divisible and continuous. Some of the old Greek had beliefs closer to present theories. It was in their writings that the word atom first appeared. They considered the atom the smallest element of which our physic ...

Information Flow in Entangled Quantum Systems
... can discover the value by measuring that observable. However, the states in which the qubit Ôholds a valueÕ in that sense are merely an isolated pair in a continuum of possible states. Hence there is a lot more than one bit of information in a qubit, though most of it is not accessible through measu ...
