Decoherence effects on quantum Fisher information of multi-qubit W states
Quantum fisher information of a parameter characterizing the sensitivity of a state with respect to parameter changes. In this paper, we study the quantum fisher information of the W state for four, five, six and seven particles in decoherence channels, such as amplitude damping, phase damping and depolarizing channel. Using Krauss operators for decoherence channels components, we investigate t...
متن کاملThe Boole Lecture Quantum Information: A Glimpse at the Strange and Intriguing Future of Information
Quantum and biological information processing could revolutionize computing and communication in the third millennium. In the 2007 Boole Lecture, we discussed the necessity to explore alternative paradigms for computing and communication and presented some striking features of quantum information processing and provided some insights into quantum parallelism as well as quantum communication and...
متن کامل6.453 Quantum Optical Communication Reading 1
Welcome to 6.453, Quantum Optical Communication. It is one of a collection of MIT classes that deals with aspects of an emerging field known as quantum information science. As you can divine from its title, 6.453 is about quantum communication, rather than quantum computation, although both of these topics fall under the general rubric of quantum information science. Moreover, 6.453 is far from...
متن کاملToolbox for Microwave-driven Quantum Logic with Trapped Ions
Trapped atomic ions are a well-advanced physical system for investigating fundamental questions of quantum physics and for quantum information science and its applications. When contemplating the scalability of trapped ions for quantum information science one notes that the use of laser light for coherent operations gives rise to technical and also physical issues that can be remedied by replac...
متن کاملProgramming with Quantum Communication
This work develops a formal framework for specifying, implementing, and analysing quantum communication protocols. We provide tools for developing simple proofs and analysing programs which involve communication, both via quantum channels and exhibiting the LOCC (local operations, classical communication) paradigm.
