... 1 Towards functional calculus The most powerful tool for describing linear transformations in finite dimensions is the theory of eigenvalues and (generalized) eigenvectors. What can we say about linear transformations in infinite dimensions? First, why do we want to say anything at all? 1. Several o ...

Entanglement in bipartite and tripartite quantum systems
... for a subsystem of a bipartite pure state is a signature of entanglement. Quantum superposition leads to a kind of correlations that cannot be explained by classical means and it is by the word entanglement that this phenomena is known. Before giving a more precise definition of entanglement, which ...

Abstract - The Budker Group
... Like classical computers, quantum computers utilize bits to store data; however, unlike a classical bit which can only be in the 0 or 1 state, a quantum bit (qbit) can be in a superposition of both the 0 and 1 state. The states of qbits are manipulated using quantum gates, which are simply unitary o ...
