Figure 1. Design of a programmable universal quantum processor. All the qubits are connected with each other via capacitors, the frequency of each qubit is controlled by external magnetic flux, each qubit can be measured by using a coplanar waveguide resonator R, the normalized charges induced on the qubit can be tuned by changing gate voltage. Single-qubit operations can be performed using pulses on the microwave XY control line, and the coupling between arbitrary two qubits can be turned on or off by changing the fluxes.
