  The Unruh-DeWitt particle detector model has found success in demonstrating
quantum information channels with non-zero channel capacity between qubits and
quantum fields. These detector models provide the necessary framework for
experimentally realizable Unruh-DeWitt Quantum Computers with near-perfect
channel capacity. We propose spin qubits with gate-controlled coupling to
Luttinger liquids as a laboratory setting for Unruh-DeWitt detectors and
general design constraints that underpin their feasibility in this and other
settings. We also present several experimental scenarios including graphene
ribbons, edges states in the quantum spin Hall phase of HgTe quantum wells, and
the recently discovered quantum anomalous Hall phase in transition metal
dichalcogenides. Theoretically, through bosonization, we show that Unruh-DeWitt
detectors can carry out Quantum Computations and when they can make perfect
quantum communication channels between qubits via the Luttinger liquid. Our
results point the way toward an all-to-all connected solid state quantum
computer and the experimental study of quantum information in quantum fields
via condensed matter physics.
