DESCRIPTION:Quantum computing\, a concept generally attributed to Feynman\
 , is currently one of the most hyped topics in science and technology. In 
 this talk\, I will provide a physics-based introduction to the subject and
  show\, as Feynman pointed out\, that quantum systems naturally offer enor
 mous potential for processing and storing data. Unfortunately\, measuremen
 ts on quantum systems are brilliant at destroying all this data (or - for 
 the Many Worlds enthusiasts - allowing each copy of ourselves access to ju
 st one piece of this data post measurement!!). I will discuss how quantum 
 algorithms circumvent the measurement problem to allow a speed up over con
 ventional computers. Finally\, I will provide a brief overview of the prog
 ress in constructing quantum computers\, mention ‘quantum supremacy’ a
 nd outline what I view as the most significant remaining challenges that n
 eed to be addressed in the field.
