What is quantum supremacy?

  • Quantum supremacy, or “quantum advantage”, is the potential ability of quantum computing devices to solve problems that classical computers cannot.
  • According to experts, we are nearing “quantum supremacy”— a nebulous frontier where quantum computers begin to do things beyond the ability of classical machines.
  • Researchers from Google are now testing a quantum computer with 72 quantum bits, or qubits — a big step up from the company’s previous nine-qubit chip.
  • In January 2018, Intel passed a milestone to build quantum-computing systems.
  • The technology giant has also unveiled a superconducting quantum test chip with 49 qubits, or enough qubits to possibly enable quantum computing.
