Experimental Implementations of Quantum Information Processing
Quantum information processing (QIP) is the study of information and information processing as governed by the laws of quantum mechanics. A theory of quantum information allows for the development of quantum computers, which could be used to greatly increase the speed of certain mathematical computations; to construct quantum simulators, capable of simulating other quantum systems; and to perfo...
متن کاملExperimental realization of noiseless subsystems for quantum information processing.
We demonstrate the protection of one bit of quantum information against all collective noise in three nuclear spins. Because no subspace of states offers this protection, the quantum bit was encoded in a proper noiseless subsystem. We therefore realize a general and efficient method for protecting quantum information. Robustness was verified for a full set of noise operators that do not disting...
متن کاملQuantum Information Processing Theory
Definition Quantum information processing theory is an alternative mathematical approach for generating theories of how an observer processes information. Typically, quantum information processing models are derived from the axiomatic principles of quantum probability theory. This probability theory may be viewed as a generalization of classic probability. Quantum information processing models ...
متن کاملNMR 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...
متن کاملWhy Quantum Information Processing
In this brief note, I will consider the following questions: (1) What is QIP? (2) Why QIP is interesting? (3) What QIP can do? (4) What QIP cannot do? (5) What are the major challenges in QIP? Some guest lecturers may also be invited for special topics on the subject.
