  2. 2. Quantum computersQuantum computersuse atoms toperform calculationHere computationdepends onprinciple ofquantum theoryQubit
  3. 3. HISTORY1982 - Feynman proposed the idea ofcreating machines based on the laws of quantummechanics instead of the laws of classical physics.1985 - David Deutsch developed the quantumTuring machine, showing that quantum circuits areuniversal. 1994 - Peter Shor came up with a quantumalgorithm to factor very large numbers in polynomial time.1997 - Lov Grover develops a quantum searchalgorithm with O(√N) complexity
  4. 4. Why quantum computerMoore’ law slowing downin 2020 it is flattenedout.Transistor cannot bemade smaller due to the lawsof Quantum mechanicsstarts to take overPost silicon era
