  • Measurement Protocol for the Entanglement Spectrum of Cold Atoms
    Physical Review X, 2016
    Co-Authors: Hannes Pichler, Guanyu Zhu, Alireza Seif, Peter Zoller, Mohammad Hafezi
    Abstract:

    Entanglement, and, in particular the entanglement spectrum, plays a major role in characterizing many-body quantum systems. While there has been a surge of theoretical works on the subject, no experimental Measurement has been performed to date because of the lack of an implementable Measurement scheme. Here, we propose a Measurement Protocol to access the entanglement spectrum of many-body states in experiments with cold atoms in optical lattices. Our scheme effectively performs a Ramsey spectroscopy of the entanglement Hamiltonian and is based on the ability to produce several copies of the state under investigation together with the possibility to perform a global swap gate between two copies conditioned on the state of an auxiliary qubit. We show how the required conditional swap gate can be implemented with cold atoms, either by using Rydberg interactions or coupling the atoms to a cavity mode. We illustrate these ideas on a simple (extended) Bose-Hubbard model where such a Measurement Protocol reveals topological features of the Haldane phase.

    Physical Review X, 2016
    Co-Authors: Hannes Pichler, Guanyu Zhu, Alireza Seif, Peter Zoller, Mohammad Hafezi
    Abstract:

    Entanglement, a key aspect of quantum mechanics, is critical to quantum information theory. Researchers theoretically show how cold atoms can be manipulated to measure the entanglement spectrum of a many-body quantum state.

  • Verification of the time-reversal Measurements Protocol for buried object detection in the soil
    2013
    Co-Authors: Robert Kedzierawski, Jean-marc Le Caillec, Witold Czarnecki
    Abstract:

    In this paper, we present the results of time-reversal Measurement Protocol verification for focusing the backscattered energy from a buried point scatterer located in an inhomogeneous medium using low frequency. Firstly, we shortly introduce the soil electromagnetic model (based on geological and hydraulic properties) that allows to simulate the electromagnetic wave propagation in an inhomogeneous medium. Secondly, the time-reversal Measurement Protocol composed of three stages, i.e. forward probing, time-reversal operation and time-reversal probing, is presented and performed by numerical simulations.

  • cisco service level assurance Protocol
    RFC, 2013
    Co-Authors: Sudhir Thombare, Murtaza Chiba, Steven Medley, Joseph Salowey, Eshwar Yedavalli, Alex Clemm
    Abstract:

    Cisco's Service-Level Assurance Protocol (Cisco's SLA Protocol) is a Performance Measurement Protocol that has been widely deployed. The Protocol is used to measure service-level parameters such as network latency, delay variation, and packet/frame loss. This document describes the Cisco SLA Protocol Measurement-Type UDP-Measurement, to enable vendor interoperability. This document is not an Internet Standards Track specification; it is published for informational purposes.

  • Individual Session Control Feature for the Two-Way Active Measurement Protocol (TWAMP)
    2010
    Co-Authors: Al Morton, Murtaza Chiba
    Abstract:

    The IETF has completed its work on the core specification of TWAMP - the Two-Way Active Measurement Protocol. This memo describes an OPTIONAL feature for TWAMP, that gives the controlling host the ability to start and stop one or more individual test sessions using Session Identifiers. The base capability of the TWAMP Protocol requires all test sessions previously requested and accepted to start and stop at the same time.
