Constructing Four-Photon States for Quantum Communication and Information Processing
We provide a method for constructing a set of four-photon states suitable for quantum communication applications. Among these states is a set of concatenated quantum code states that span a decoherence-free subspace that is robust under collective-local as well as global dephasing noise. This method requires only the use of spontaneous parametric down-conversion, quantum state post-selection, a...
متن کاملClassical Communication Cost in Distributed Quantum Information Processing—A generalization of Quantum Communication Complexity
We study the amount of classical communication needed for distributed quantum information processing. In particular, we introduce the concept of ”remote preparation” of a quantum state. Given an ensemble of states, Alice’s task is to help Bob in a distant laboratory to prepare a state of her choice. We find several examples of an ensemble with an entropy S where the remote preparation can be do...
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.
