Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional atomic object traps are used, then atomic objects can be trapped, but the number of electrical signals required increases with the number of atomic objects, reducing efficiency
Solution Approach 1:
The trap is divided into multiple zones along the longitudinal axis, with each zone having dedicated TT electrodes that can be independently controlled. This segmentation allows different groups of atomic objects to be manipulated with separate electrical signals, reducing the overall complexity compared to controlling each atom individually while still enabling precise manipulation of multiple atomic objects simultaneously.
Solution Approach 2:
The TT electrodes serve multiple functions: they can create potential wells to trap atomic objects, transport atomic objects between zones, and manipulate quantum states. This multi-functionality allows a single set of electrodes to handle various operations on multiple atomic objects without requiring separate dedicated signals for each function, thereby reducing the total number of electrical signals needed.
2Quantity of substance
If more atomic objects are trapped simultaneously, then quantum computing capacity increases, but the physical space required increases
Solution Approach 1:
The patent employs a three-dimensional concentric electrode configuration with RF electrodes forming an elliptical cylinder and TT electrodes arranged in multiple radial layers. This spatial arrangement in multiple dimensions allows the trap to accommodate a larger number of atomic objects within a compact footprint by utilizing vertical and radial spacing rather than only horizontal expansion.
Solution Approach 2:
The electrode structure features nested concentric layers with inner and outer TT electrode sequences arranged radially around the central RF electrodes. This nesting arrangement maximizes the use of available space by placing functional elements in multiple radial layers, enabling the trap to hold more atomic objects without proportionally increasing the overall apparatus size.
3Area of stationary object
If the trap apparatus is made more compact, then space efficiency improves, but electrical connectivity and signal distribution become more difficult
Solution Approach 1:
The TT electrodes are divided into multiple independently controllable groups or zones along the longitudinal axis. Each zone can be addressed by separate electrical signals, allowing for modular control that simplifies the electrical connectivity architecture. This segmentation enables compact design while maintaining manageable signal distribution through zoned control rather than requiring complex individual addressing of all electrodes.
Solution Approach 2:
Adjacent TT electrodes within the same zone are electrically connected and controlled by a single electrical signal. This merging of control signals for groups of electrodes reduces the total number of independent connections required, simplifying the electrical connectivity infrastructure while still enabling precise manipulation of atomic objects in different spatial zones through selective activation of electrode groups.
