- Abstract: Tavis-Cummings (TC) cavity quantum electrodynamical effects, describing the
interaction of $N$ atoms with an optical resonator, are at the core of atomic,
optical and solid state physics. The full numerical simulation of TC dynamics
scales exponentially with the number of atoms. By restricting the open quantum
system to a single excitation, typical of experimental realizations in quantum
optics, we analytically solve the TC model with an arbitrary number of atoms
with linear complexity. This solution allows us to devise the Quantum Mapping
Algorithm of Resonator Interaction with $N$ Atoms (Q-MARINA), an intuitive TC
mapping to a quantum circuit with linear space and time scaling, whose $N+1$
qubits represent atoms and a lossy cavity, while the dynamics is encoded
through $2N$ entangling gates. Finally, we benchmark the robustness of the
algorithm on a quantum simulator and superconducting quantum processors against
the quantum master equation solution on a classical computer.

coherent dynamics and control of spin qubits are essential requirements for quantum technology.
A prominent challenge for coherent control of a spin qubit in a set of qubits is the destructive effect of the applied magnetic field on the coherent dynamics of neighbouring qubits.
We propose a novel scheme to characterize the coherent dynamics of these quantum systems and to coherently control them using a magnetic field.
