Building A Quantum Computer Using Silicon Chips (IET Central London Network)
“When a computer can manipulate the state efficiently, it can start doing a lot more” explained John Morton, co-founder, and CTO of Quantum Motion at the January 2023, IET Central London Network evening lecture at IET Savoy Place, hosted by Dr Mathew Davies. He spoke about the journey of quantum computing, including how the Colossus computer first built in Dollis Hill, London, 1943 used vacuum-tubes to control electric current flow in high vacuums between electrodes. He highlighted the journey of ‘Physical Resources per Bit’ - from Mechanical and Vacuum technology that need room-size space, through to Silicon transistors, that became as small as 12mm2. He moved on to talk about the differences between classical computers vs quantum computers in terms of processing speeds from days into seconds…
