Optical simulation of quantum logic
A constructive method for simulating small-scale quantum circuits by use of linear optical devices is presented. It relies on the representation of several quantum bits by a single photon, and on the implementation of universal quantum gates using simple optical components ~beam splitters, phase shifters, etc.!. This suggests that the optical realization of small quantum networks with present-d...
متن کاملdevelopment of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Quantum Logic Gates in Optical Lattices
We propose a new system for implementing quantum logic gates: neutral atoms trapped in a very far-off-resonance optical lattice. Pairs of atoms are made to occupy the same well by varying the polarization of the trapping lasers, and then a near-resonant electric dipole is induced by an auxiliary laser. A controlled-NOT can be implemented by conditioning the target atomic resonance on a resolvab...

متن کاملSimulation of Quantum Automata Cellular Logic Devices for Quantum Logic Circuits E.N.Ganesh*
One of the challenges to scale down transistor size is leakage current through gate oxide. This leakage current results from quantum mechanical tunneling of electrons from the gate electrode through the oxide and in to the transistor channel. Instead of maintaining transistor functionality at smaller scales, a new technology called Quantum cellular automata technology is developed by Lent and K...
