"Quantum Information", pdf (letter size) |
A talk given to the monthly meeting of the IEEE Society of East Tennessee in Oak Ridge, TN on 17 November 2009. The talk provided a technical overview of the principles and key ides in the field of quantum information alongside several notable applications. |
"Simultaneous Teleportation of Multiple Photonic Degrees of Freedom", pdf (letter size) |
A talk given at the Single Photon Workshop sponsored by the National Institute for Science and Technology at Boulder, Colorado on 4 November 2009. The talk, delivered by Ryan Bennink, reported how quantum information encoded into multiple photonic degrees of freedom may be simultaneously teleported using a single, common physical platform. |
"Sensing Intruders Using Entanglement: A Photonic Quantum Fence", pdf (letter size) |
A talk given at the SPIE Defense, Sensing, and Security conference in Orlando, FL on 16 April 2009 to the conference on Quantum Information and Computation VII. The presentation includes theoretical and experimental results demonstrating the feasibilty of sensing an intruder who actively attemps to spoof an alarm system. |
"Intrusion Detection with Quantum Mechanics: A Photonic Quantum Fence", pdf (letter size) |
A poster presented given at the 26th Army Science Conference in Orlando, FL on 3 December 2008. The presentation includes theoretical and experimental results demonstrating the feasibilty of sensing an intruder who actively attemps to spoof an alarm system. |
"Total Teleportation of a Single-photon state", pdf (letter size) |
A presentation given at SPIE Optics+Photonics 2008 in San Diego, CA on 14 August 2008 to the conference on Quantum Communication and Quantum Imaging VI as part of the session on Quantum Technologies III. This presentation includes theoretical results on the experimental feasibility of teleporting the complete quantum state of a single photon. |
"Simultaneous Teleportation of the Spectral and Polarization States of a Photon", pdf (letter size) |
A poster presented in absentia at a joint session of CLEO/QELS 2008 (JTuA110) describing how quantum information encoded into the spectral and polarization degrees of freedom of a single photon can be simultaneously teleported using a measurment device based on sum-frequency and difference-frequency generation. In particular, it is only when spectral entanglement is maximal (infinite) that the spectral state is faithfully teleported.
|
"The Quantum Fence: Intrusion Detection with Quantum Mechanics", pdf (letter size) |
A poster presented at the 2007 DOE Day of Science, an event held on October 29th in Knoxville, TN to showcase research at the national laboratories. The poster presents the quantum fence, an intrusion detection system that uses quantum-mechanical entanglement to signal a breach of a physical perimeter. The basis for this idea stems from our previous research on the effects of spectrally multimode, polarization-entangled photons.
|
A poster presented, in absentia, at the Ninth Rochester Conference on Coherence and Quantum Optics. The poster reports on the role of spectral entanglement and the role of source configuration in the operation of the entanglement swapping and type-I fusion gates to generate polarization-entangled photons.
|
"Quantum Teleportation with Entangled Multimode Photons", pdf |
Colloquium presentation.
|
"Cluster States and Fusion Gates", ORNL Internal, 21 November 2006 pdf
|
A vignette of cluster states and fusion gates plus my analysis of how spectral entanglement affects cluster state preparation.
|
"Spectral Effects in Quantum Teleportation", Quantum Computing and Program Review, June 2006 pdf
|
A poster presentation on how the distinguishing information inherent to type-II SPDC effects quantum optical implementations of the quantum teleportation protocol. The maximal teleportation fidelity is calculated for varying degrees of spectral entanglement and the optimal bandwidth of message photon is determined.
|
"Spectral Effects in Quantum Teleportation", Quantum Electronics and Laser Science, May 2006 pdf
|
A short talk on how multimode effects can reduce the fidelity of quantum teleportation. Distinguishing information inherent to type-II SPDC is quantified for varying degrees of spectral correlation, i.e. spectral entanglement, and compared to the teleportation fidelity.
|
"Nonlinear Wavepacket Interferometry and Molecular State Reconstruction", Optics in the Southeast, October 2005 pdf
|
A short presentation on nonlinear wave packet interferometry for molecular state reconstruction. An overview of the theoretical basis and how such an experiment might be carried out. Includes numerical simulations of the multimode reconstruction of lithium dimer rovibrational wave packets shaped by chirped ultrashort laser pulses.
