By harnessing aspects of quantum mechanics, communication and information processing could be radically transformed. Promising forms of quantum information technology include optical quantum cryptographic systems and computing using photons for quantum logic operations. As with current information processing systems, some form of memory will be required. Quantum repeaters, which are required fo...

Submitted for the DAMOP14 Meeting of The American Physical Society Towards a cavity electromagnetically induced transparency based quantum gate EDEN FIGUEROA, ZAKARY BURKLEY, BERTUS JORDAAN, CARL CHEUNG, CHRISTIAN NOELLEKE, CONNOR KUPCHAK, Stony Brook University — The processing of quantum information with photons and atoms has been established as one of the strongest candidates for future quan...

administrative regulations for water flow decrease distribution efficiency and effect the economical operation of irrigation networks. complications in distribution systems and the decrease in availability of water require study of the hydraulic performance of existing flow control structures. control systems designed by neyrpic (zayandeh rud network) and usbr (doroodzan network) were investiga...

In this paper, a novel design of an all-optical half-adder (HA) based on two two-ring resonators in two-dimensional square-lattice photonic crystal (PC) structure without nonlinear materials is proposed. The HA comprises AND and XOR gates where each gate composed cross-shaped waveguides 2D PC that are filled with silicon (Si) rods silica (SiO2). analyzed simulated using plane-wave expansion (PW...

On-chip optical data processing and photonic quantum integrated circuits require the integration of densely packed directional couplers at the nanoscale. However, the inherent evanescent coupling at this length scale severely limits the compactness of such on-chip photonic circuits. Here, inspired by the adiabatic elimination in a N-level atomic system, we report an experimental realization of ...

A deflection routing algorithm that can be applied to a novel self-routing address scheme for networks with arbitrary topology is proposed. The proposed deflection routing algorithm can be implemented all-optically using bitwise optical logic gates. Besides the primary output link selection, alternate output link choices by a packet at each node in case of deflection are also encoded in the add...

We propose to use a single mesoscopic ensemble of trapped polar molecules for quantum computing. A "holographic quantum register" with hundreds of qubits is encoded in collective excitations with definite spatial phase variations. Each phase pattern is uniquely addressed by optical Raman processes with classical optical fields, while one- and two-qubit gates and qubit readout are accomplished b...
