Why the race to build a quantum computer?

Quantum computers are still in their infancy, but governments and corporations are spending billions trying to turn them into workable technology. Neal Razzell finds out why.

Quantum computers could transform our lives. Based on a branch of Physics that even Einstein found "spooky", the machines are still in their infancy. But governments and corporations are spending billions trying to turn them into workable technology. Neal Razzell finds out why by talking to four experts:

Shohini Ghose, Professor of Physics and Computer Science at Wilfred Laurier University in Canada
Stephanie Wehner, Professor in Quantum Information at Delft University of Technology in the Netherlands
Winifried Hensinger, Professor or Quantum Technologies at the University of Sussex
Jonathan Dowling, Professor of Theoretical Physics at the University of Louisiana and author of 'Quantum Technology - The Second Quantum Revolution' and 'Schrödinger's Killer App - Race to Build the World's First Quantum Computer'.
