Realization

Physical implementations, from which the most relevant are described in the complementing section about Realization, include:

• NMR

• QED

• Photonics

• Neutral Atoms

• Trapped Ions

• Superconducting Circuits

• Quantum Dots

• NV Centers

How to characterize the capability of the hardware?

• One ansatz is the Quantum Volume [28]:

  “Quantum Volume = \(2^n\)

  where N is the (width=depth) of the largest random square circuit that can be successfully run on a quantum computing system.”

To investigate:

• Superconductor–semiconductor hybrid-circuit quantum electrodynamics [24]:

  “hybrid ‘super–semi’ quantum systems, which coherently couple superconducting cavities to semiconductor quantum dots”
