From: One-dimensional quantum computing with a ‘segmented chain’ is feasible with today’s gate fidelities
Quantum architectures. a A 2D array of coupled qubits fills the plane, necessitating the challenging task of bringing in control lines from above. b Alternatively a network of modules can be linked by optical channels, but this requires controlled interfacing of static and flying qubits (photons). c A potentially more simple architecture is the 1D qubit array with the segmented chain structure, which allows in-plane lateral access for control lines. Here we depict a snaking path, to illustrate that a 1D array can efficiently use a 2D surface
