The 5 Criteria for Quantum Computers + 2 for Quantum Internet

Below are the seven principles that form the core engineering blueprint for the coming quantum communication era; a network of entangled processors exchanging qubits globally.

The DiVincenzo Criteria for Quantum Computers:
  • Scalable Qubits: The system must have a well-defined, controllable set of quantum bits.
  • Initialization: Qubits must be initialized to known states, often |0⟩.
  • Decoherence Management: The system must maintain coherence long enough for computation.
  • Universal Gates: The systems must be able to perform a universal set of quantum gates that allows any quantum computation to be built from these basic operations.
  • Readout: The system must support efficient/accurate measurement of qubit states to extract meaningful computational results.
The Quantum Internet Extensions:
  1. Entanglement Distribution: The system must be capable of creating, distributing, and maintaining quantum entanglement between distant nodes in a network.
  2. Quantum Repeater and Error Correction: These techniques are required to preserve signal fidelity and reduce errors as quantum information is transmitted over long distances.
