NMR Quantum Information Processing

NMR Quantum Information Processing

Nuclear magnetic resonance (NMR) has provided a valuable experimental testbed for quantum information processing (QIP). Here, we briefly review the use of nuclear spins as qubits, and discuss the current status of NMR-QIP. Advances in the techniques available for control are described along with the various implementations of quantum algorithms and quantum simulations that have been performed u...

Quantum Information Processing with NMR

This experiment will let you perform a series of simple quantum computations on a two spin system, demonstrating one and two quantum-bit quantum logic gates, and a circuit implementing the Deutsch-Jozsa quantum algorithm. You will use NMR techniques to manipulate the state of a proton and a carbon nucleus in a chloroform molecule, measuring ensemble nuclear magnetization. You should know Matlab...

Quantum Information Processing through Liquid NMR

Decades ago, the transistor was invented. With many transistors together in certain configurations, chips and integrated circuits were born. The transistor eventually found its way into a device commonly known as a computer. Ever since, more and more devices have had these semiconductors in them, which switch on or off to store information. Nowadays, a standard CPU or brain of a computer has ne...

NMR quantum information processing and entanglement

In this essay we discuss the issue of quantum information and recent nuclear magnetic resonance (NMR) experiments. We explain why these experiments should be regarded as quantum information processing (QIP) despite the fact that, in present liquid state NMR experiments, no entanglement is found. We comment on how these experiments contribute to the future of QIP and include a brief discussion o...
