1Ease of operation
If T-junction techniques are used for braiding anyons, then anyon braiding can be achieved, but the system requires time-dependent tuning of local chemical potential which is hard to perform experimentally and is limited to one-dimensional systems
Solution Approach 1:
The patent transitions from one-dimensional T-junction braiding to two-dimensional anyon manipulation using vortex world lines in the superconductor. The vortex world lines extend through the bulk of the superconductor, enabling braiding operations in two spatial dimensions rather than confined to a one-dimensional wire network.
Solution Approach 2:
The patent introduces magnetic textures (skyrmions) as intermediary objects that bind to vortex world lines in the superconductor. These magnetic textures serve as controllable mediators that localize anyons at vortex cores, enabling manipulation through magnetic field gradients without requiring direct electrical tuning of the superconductor.
2Productivity
If conventional quantum computation is used, then quantum states can be manipulated, but small cumulative perturbations cause decoherence and introduce errors
Solution Approach 1:
The patent changes the fundamental parameter for encoding quantum information from local quantum states to topological properties of vortex world lines. The quantum information is stored in the braiding topology rather than in fragile local states, making it robust against small perturbations that cannot change the topological class of the braids.
Solution Approach 2:
The patent creates a composite system combining a superconductor with magnetic texture layers. This composite structure enables the formation of magnetic texture-vortex pairs that bind anyons, combining the topological protection of superconductivity with the controllable manipulation capabilities of magnetic textures.
