Engineering Contradiction Analysis
1Speed
If electrical signals are converted into optical signals for data transfer between qubit chips, then data transfer capability is improved, but quantum information loss increases
Solution Approach 1:
The patent replaces the optical signal conversion system with a direct electromagnetic coupling system using resonant antennas. Instead of converting electrical signals to optical signals and back, the system uses electromagnetic resonance to directly transfer quantum information between qubit chips through inductively coupled antennas, eliminating the conversion process that causes information loss
Solution Approach 2:
The patent introduces resonant antennas as an intermediary between qubit chips. These antennas are tuned to the same resonant frequency and coupled inductively, serving as a mediator that enables direct electromagnetic energy and information transfer without signal conversion, thus preserving quantum information integrity
2Adaptability or versatility
If waveguide chips are used to connect qubit chips, then connection capability is improved, but reliability of quantum information exchange deteriorates
Solution Approach 1:
The patent replaces the waveguide-based mechanical connection system with an electromagnetic resonance-based wireless coupling system. Instead of using physical waveguide structures that require precise mechanical alignment and conversion interfaces, the system uses inductively coupled resonant antennas that transfer quantum information through electromagnetic fields, significantly improving reliability
Solution Approach 2:
The patent changes the operating parameters from optical frequency conversion to resonant electromagnetic frequency coupling. By tuning the antennas to the same resonant frequency as the qubit chips, the system achieves efficient and reliable quantum information transfer without the reliability issues associated with waveguide conversions
