Google’s claims on Quantum breakthrough

  • Google claims to have achieved a long-sought breakthrough called “quantum supremacy”, which could allow new kinds of computers to do calculations at speeds that are inconceivable with today’s technology.
  • Google’s quantum computer took under 3 minutes for a calculation that would take a supercomputer 10,000 years.
  • Google’s quantum computer, named Sycamore, used a 53-qubit processor to generate a sequence of millions of numbers.
  • Traditional computers follow the principles of a Turing machine and perform calculations by processing “bits” of information, with each bit holding either a 1 or a 0.
  • Quantum computing relies on the way some objects act at the subatomic level or when exposed to extreme cold, like the metal chilled to nearly 460 degrees below zero.
  • By harnessing this odd behavior, scientists can build a quantum bit, or “qubit”. A qubit is not always 0 or 1, but can be both at the same time (a state called quantum superposition). Only at the end of the computation would you know which, but during the computation process, its exact state is indeterminate.
  • Quantum machines look nothing like a regular computer. They are large cylinders of metal and twisted wires that are dropped into stainless steel refrigerators. Information is sent to the machine, as is to a traditional computer chip, and calculations are received in return.
