Quantum Information Processing: Algorithms, Technologies and Challenges
Quantum Computation (QC) is a type of computation where unitary and measurement operations are executed on linear superpositions of basis states. This paper provides a brief introduction to QC. We begin with a discussion of basic models for QC such as quantum TMs, quantum gates and circuits and related complexity results. We then discuss a number of topics in quantum information theory, includi...
متن کاملQuantum Algorithms: Entanglement Enhanced Information Processing
We discuss the fundamental role of entanglement as the essential nonclassical feature providing the computational speedup in the known quantum algorithms. We review the construction of the Fourier transform on an Abelian group and the principles underlying the fast Fourier transform algorithm. We describe the implementation of the FFT algorithm for the group of integers modulo 2 in the quantum ...
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.
