REMINDER: Daniel Gauthier Seminar TODAY at 3:00 pm

[Palmer, Shelley]

Folks,

Daniel Gauthier (Duke University) will be presenting a Special Seminar today at 3:00 pm in the Smith Seminar Room.

Title:  Information on a photon"

Abstract:

The field of quantum information science aims to leverage the properties of quantum mechanics to realize new approaches for computing and communication.  In this presentation, I will review the basic building blocks of a classical optical communication system.  From there, I will describe a communication system in which the photonic wavepackets have less than one photon - and hence entering the quantum regime.  Surprisingly,  the number of bits that can be encoded on a single quanta is nearly limitless.  I will show how this property, along with the indistinguishability of certain quantum states, can be used to realize a quantum communication system for sharing a secret key between two parties.  This system is secure against an attack by an eavesdropper due to the fundamental properties of quantum mechanics.

Please come to hear Dr. Gauthier's talk.  A reception will precede the talk at 2:45pm in the atrium.

Thank you,


Shelley
