Briefing
  • Quantum Computer Simulation – Researchers at ETH Zurich have demonstrated simulating 45-qubit quantum computer on fifth most powerful supercomputer in world, Cory II, at Lawrence Berkeley National Laboratory
  • Classical Computing Limitations – Previous attempts to simulate quantum computers have stopped at 42 qubits due to computing limitation of classical computers
  • Solution Achieved – Reduced computational overhead to overcome barrier in classical computing, improving simulation speed by order of magnitude
  • Future Simulations – Research indicates simulation of 49-qubit quantum computer, when quantum computers match capability of most powerful supercomputer, is possible in future
