Quantum waveguide array generator for performing Fourier transforms: Alternate route to quantum computing
Richard Akis, David K. Ferry · Applied Physics Letters · 2001
Recently, quantum computing has gained attention as a possible means of greatly increasing the speed of certain calculations when compared with traditional, binary computing. A key part of many quantum computing algorithms is the performance of a Fourier transform. In this letter, we propose a quantum waveguide array device that can perform such operations quickly with a parallel approach that uses the analog properties of waves and rather than the qubit concept.
