SUMMARY:Ultracold Inferno” to Quantum Computing: Collisions Under Qu
 antum Control\, Physics Department Colloquium\, Micheline Soley \, UW 
 Madison - Department of Chemisty
DESCRIPTION:Low-energy ultracold molecules offer an unprecedented oppo
 rtunity to examine chemical reactions at the level of individual quant
 um states and to develop quantum computers based on ultracold molecula
 r qubits. Theoretical developments are needed to help expedite these t
 echnologies\, but are stymied by the fact that ultracold molecular pro
 cesses are notoriously difficult to simulate. In this talk\, I will pr
 esent a method that addresses this problem based on the finding that\,
  whereas low temperatures are typically associated with quantum mechan
 ics\, an approach based on classical and semiclassical methods can red
 uce anomalous reflection error in certain ultracold simulations from 1
 00% to 0% at a single energy. This approach provides a tool for tackli
 ng the “ultracold inferno” problem of understanding how molecules 
 are produced close to zero Kelvin. This semiclassical technique\, comb
 ined with a theory from optics\, provides an explanation of and the me
 ans to reveal long-sought-after PT-symmetry behavior in quantum mechan
 ics.  In addition\, the talk will discuss quantum computing algorithms
 \, both on quantum computers and classical computers using advanced da
 ta compression techniques.
