What is an Optical Lattice ?

• Intersecting laser beams cool and trap atoms
• Nobel prizes in Physics 1997 and 2001

Prof Bill Phillips (Nobel Laureate) at Queens
in 2002 to open International Centre for
Experimental Physics

Quantum Information Technology
J. S. Bell (Queens graduate) Bells
inequality (1964)

• Single atom divided over many locations
  superposition
• Atoms share information entanglement

Classical bits of information 3 bits may
encode for 1 of 8 possibilities. Quantum bits
of information ? 8 possibilities are
represented simultaneously. And this is just
for three bits Consider billions of bits
!!!! Quantum Information is exponentially better
for information processing

Economic Importance of Quantum Information
Technology
Ireland (Science Foundation Ireland)
spending 8 million Euro over next 5
years US spending 10 million per
year UK spending 9 million over next
5 years on Quantum
