- Abstract: Magnetic solitons can constitute a means for manipulating qubits from a
distance. This would overcome the necessity of directly applying selective
magnetic fields, which is unfeasible in the case of a matrix of qubits embedded
in a solid-state quantum device. If the latter contained one-dimensional
Heisenberg spin chains coupled to each qubit, one can originate a soliton in a
selected chain by applying a time-dependent field at one end of it, far from
the qubits. The generation of realistic solitons has been simulated. When a
suitable soliton passes by, the coupled qubit undergoes nontrivial operations,
even in the presence of moderate thermal noise.

We present evidence of sizable and coherent coupling of the qubit with the spin states of a nearby quantum dot, demonstrating that appropriate spin-electric coupling may enable a charge-based two-qubit gate in a (1,1) charge configuration.

This unique coupling is found to enable control over the equilibrium magnon squeezing and a deterministic generation of squeezed even Fock states.
