Nuclear magnetic resonance quantum information processing.
For the past decade, nuclear magnetic resonance (NMR) has been established as a main experimental technique for testing quantum protocols in small systems. This Theme Issue presents recent advances and major challenges of NMR quantum information possessing (QIP), including contributions by researchers from 10 different countries. In this introduction, after a short comment on NMR-QIP basics, we...
متن کاملQuantum information processing by nuclear magnetic resonance on quadrupolar nuclei.
Nuclear magnetic resonance is viewed as an important technique for the implementation of many quantum information algorithms and protocols. Although the most straightforward approach is to use the two-level system composed of spin 1/2 nuclei as qubits, quadrupolar nuclei, which possess a spin greater than 1/2, are being used as an alternative. In this study, we show some unique features of quad...
متن کاملQuantum Information Systems: Using a Two-Spin System and Nuclear Magnetic Resonance
Information systems are an essential part of everyday life. Standard computers rely on the detection of charge to process information; quantum computers use quantum states to represent information[15]. There are a few different techniques that can be used to complete quantum computations, including iontrap[3], quantum dots[1], and nuclear magnetic resonance (NMR) experiments. In the case of our...
متن کاملImplementation of half adder and half subtractor with a simple and universal DNA-based platform
As a powerful material, DNA presents great advantages in the fabrication of molecular devices and higher-order logic circuits. Herein, by making use of the hybridization and displacement of DNA strands, as well as the formation and dissociation of a G-quadruplex, a simple and universal DNA-based platform is developed to implement half-adder and half-subtractor arithmetic processes. The novel fe...
متن کاملMolecular beacon-based half-adder and half-subtractor.
This work demonstrates two DNA-based logic circuits that behave as a half-adder and a half-subtractor. A half-adder is composed of an AND gate and an XOR gate, whereas a half-subtractor consists of an INH gate and an XOR gate. The proposed designs are inspired by molecular beacons.
