<pre>Dear colleagues,
a reminder of today's seminar at 10:30 am.
________________________________________
On Tuesday 21 May 2013, in Room 3.14 of the John Anderson Building at 10:30 am
Dr. Alison Yao will give a 30 minute presentation on:
"Quantum Optics with a Twist"
Abstract:
Spatial modes carrying orbital angular momentum (OAM) - "twisted" light beams - are of
considerable interest for quantum information purposes as they have the potential to
generate multi-dimensional entangled states. In order to perform useful measurements,
however, we first need to know the fundamental limit imposed on the precision with which
conjugate pairs of physical properties can be measured. I will give a brief overview of light
carrying OAM and explain the form of the corresponding uncertainty relationship. I will also
introduce new states which we have recently shown to minimise the uncertainty product.
A key resource for quantum information is entanglement - the ability to infer information about
one particle by a distant measurement of a second. We have recently performed a quantitative
study of the degree of entanglement between two photons and demonstrated an
Einstein-Rosen-Podolsky (EPR) effect an order of magnitude stronger than for independent
particles. I will review this work and demonstrate how we can 'engineer' the number of
entangled states that can be produced.
