The Einstein Podolsky Rosen Paradox
John Howell Dept of Physics and Astronomy University of Rochester
The "Einstein Podolsky Rosen Paradox" was a gedanken experiment proposed
in 1935 to point out that the wavefunction description of quantum
mechanics was incomplete. EPR used a two-particle wavefunction, which was continuously entangled in position and momentum, to show that each
particle must both be in a position and a momentum eigenstate
simultaneously. This conclusion was in violation of Heisenberg's
uncertainty principle. Much interest and study over the last several
decades has illucidated many of the points in the EPR paradox. Recently,
our group demonstrated momentum-position and time-energy violations of
what has now been defined as the EPR bound. These experiments will be
discussed along with their relevance to quantum information and imaging. |
