Methods for a linear optical quantum Fredkin gate

Quantum optical Fredkin gate.

Self-stabilized quantum optical Fredkin gate.

The quantum optical Fredkin gate is an indispensable resource for networkable quantum applications. Its performance in practical implementations, however, is limited fundamentally by the inherent quantum fluctuations of the pump waves. We demonstrate a method to overcome this drawback by exploiting stimulated Raman scattering in fiber-based implementations. Using a Sagnac fiber-loop switch as a...

A quantum Fredkin gate.

Minimizing the resources required to build logic gates into useful processing circuits is key to realizing quantum computers. Although the salient features of a quantum computer have been shown in proof-of-principle experiments, difficulties in scaling quantum systems have made more complex operations intractable. This is exemplified in the classical Fredkin (controlled-SWAP) gate for which, de...

development 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...

Design and Implementation of Super Class Integrated Qubit Fredkin Gate For Quantum Reversible Circuits

Reversible Logic is an emerging technology; it has hellocious applications in various fields. Reversible logic implementation reduces loss of entropy because of bit manipulations. Conservative reversible logic gate obeys reversible logic rules and also satisfies the property that there is equal number of 1s in the outputs as in the inputs. In this work, modified design of SCRL (Super Conservati...
