Entanglement in Random Subspaces
arXiv:quant-ph/0409157 · doi:10.1063/1.1834421
Abstract
The selection of random subspaces plays a role in quantum information theory analogous to the role of random strings in classical information theory. Recent applications have included protocols achieving the quantum channel capacity and methods for extending superdense coding from bits to qubits. In addition, random subspaces have proved useful for studying the structure of bipartite and multipartite entanglement.
