Recommendation

Quantum mechanics remains one of the most robust and puzzling fields of science. It is now set to make the first fundamental change in computing since Alan Turing’s code-breaking efforts in World War II. The strange nature of qubits requires a new approach to programming and algorithms. Yet the true potential of quantum computing will only be clear once the “Entangled Web” becomes as ordinary a miracle as the smartphone in your pocket.

Take-Aways

  • Quantum computers are fundamentally different from conventional computers.
  • Quantum computing offers unforeseen security because any hack must leave traces.
  • Quantum entanglement and quantum teleportation allow instant and secure networking of quantum computers.
