Description |
The quantum analogue of a classical random walk, namely the quantum walk, has evoked considerable research interest in recent years. Initially a mere intellectual curiosity, this concept has now gained importance as it has. been shown to be an universal primitive for quantum computing, promising speedup of execution of a variety of tasks. The talk will begin with a brief introduction to quantum walks and will then be followed by a description of physical systems that have formed the subject of investigation in this context. Experimental realizations of quantum walks- by ions, atoms and light- will be discussed. Finally, the specific cases of quantum walk of cold atoms in real space in a double optical lattice and the quantum walk of light in frequency space will be elaborated upon. |
