Physics@FOM Veldhoven 2016, Anton Zeilinger - Quantum teleportation and ...
Δημοσιεύτηκε στις 9 Φεβ 2016
Quantum teleportation, entanglement, and Einstein’s question, “What is light?”
It
is well known that Einstein received the Nobel Prize for the
groundbreaking idea of 1905, his annus mirabilis, that light consists of
particles, today called photons. In 1935, he discovered together with
Podolsky and Rosen that two quantum systems can be connected stronger
than in classical physics. For that situation the Austrian Nobel Prize
winner Erwin Schrödinger coined the name “entanglement” and called it
“the essential feature of quantum mechanics” while Einstein, dismissed
it as “spooky action at a distance”.
Technical progress in
creating and handling entangled photon states not only led to
experimental realization of such entangled states but also the discovery
of novel phenomena, including, for example, multi-particle entanglement
and quantum teleportation. These are not just intellectual curiosities,
but they lay the foundations for a new information technology, with
concepts such as quantum communication, quantum cryptography and quantum
computation.
In the talk, Zeilinger presents some of the most
recent experimental results, particularly on long-distance quantum
communication and on the implementation of quantum states in
higher-dimensional Hilbert spaces. He also discusses future possible
applications in quantum information systems. These will, for example,
include experiments using satellite-based quantum communication on a
worldwide scale.
Towards the end of his life Einstein commented
that despite years of conscious brooding, he did not come closer to
answering the question “What is light?” It would be fascinating to know
his position about these recent developments.
About the conference:
Physics@FOM
Veldhoven is a large congress that provides a topical overview of
physics in the Netherlands. It is organised by the Foundation for
Fundamental Research on Matter (FOM) and takes place each year in
January. Traditionally, young researchers are given the chance to
present themselves and their work alongside renowned names from the
Dutch and international physics community. The programme covers Light
and matter, Atomic, molecular and optical physics, Nanoscience and
nanotechnology, Statistical physics and Soft condensed matter, Surfaces
and interfaces, Physics of fluids, Subatomic physics, Plasma and fusion
physics, and Strongly correlated systems.
