Engineering Contradiction Analysis
1Reliability
If quantum mechanical calculations are performed on existing quantum computers, then quantum operations can be executed, but accuracy and reliability deteriorate due to errors from relaxation, decoherence, and control imperfections
Solution Approach 1:
The quantum computer is divided into distinct operational parts: a fermion operation part for manipulating quantum element states and a boson operation part for coupling bosonic fields to quantum elements. This segmentation allows independent optimization of each part to minimize their respective error sources while maintaining overall calculation reliability.
Solution Approach 2:
Bosonic fields are introduced as an intermediary between the controlling system and the quantum elements. The boson operation part couples these fields to quantum elements, enabling controlled interactions while isolating the quantum elements from direct control imperfections. This intermediary layer reduces the transmission of control errors to the quantum system.
2Adaptability or versatility
If the number of qubits and quantum operations are increased to solve more complex problems, then problem-solving capability is improved, but accuracy deteriorates due to accumulated errors from relaxation and decoherence
Solution Approach 1:
By segmenting the quantum computer into fermion and boson operation parts, each handling specific aspects of the calculation, the system can tackle more complex problems without proportionally increasing error accumulation. The fermion part handles quantum element manipulation while the boson part manages field couplings, distributing the computational load and error sources across independent modules.
Solution Approach 2:
The system dynamically couples bosonic fields to quantum elements based on the specific problem requirements. This dynamic coupling allows the system to adapt its complexity to the problem at hand, engaging only the necessary quantum operations and minimizing unnecessary entanglement operations that would accumulate errors.
3Measurement precision
If entanglement operations are increased to represent interacting quantities, then accuracy in representing complex interactions is improved, but resource intensity and error susceptibility increase
Solution Approach 1:
Bosonic fields serve as intermediaries to represent interacting quantities without requiring extensive entanglement operations between quantum elements. The boson operation part couples these fields to quantum elements, enabling the representation of complex interactions through field-mediated interactions rather than direct multi-qubit entanglement, thereby reducing resource intensity.
Solution Approach 2:
The system substitutes direct quantum mechanical entanglement operations with bosonic field couplings for representing certain types of interactions. This substitution replaces resource-intensive entanglement operations with more efficient field-based interactions, maintaining accuracy while reducing computational resources and error susceptibility.
