Quantum logic using correlated one-dimensional quantum walks

By Yoav Lahini, Gregory R. Steinbrecher, Adam D. Bookatz and Dirk Englund


Quantum computing through quantum walks The behavior of quantum particles walking on a lattice can be exploited to design quantum gates. Quantum gates, which are the building blocks of a general purpose quantum computer, are typically designed in easy to model physical systems where the necessary behavior for the gate operation can be explicitly written out. In contrast, a collaboration between the Physics and Electrical Engineering departments at MIT has shown that the behavior of much more complicated quantum systems can be engineered, with the aid of numerical optimization, to perform the full set of necessary operations for a quantum computer. This insight expands the range of platforms that could be useful for quantum information processing, helping push towards the realization of a general purpose quantum computer
