- Abstract: Rare earth emitters enable critical quantum resources including spin qubits,
single photon sources, and quantum memories. Yet, probing of single ions
remains challenging due to low emission rate of their intra-4f optical
transitions. One feasible approach is through Purcell enhanced emission in
optical cavities. The ability to modulate cavity-ion coupling in real time will
further elevate the capacity of such systems. Here, we demonstrate direct
control of single ion emission by embedding erbium dopants in an
electro-optically active photonic crystal cavity patterned from thin-film
lithium niobate. Purcell factor over 170 enables single ion detection, which is
verified by second-order autocorrelation measurement. Dynamic control of
emission rate is realized by leveraging electro-optic tuning of resonance
frequency. Using this feature, storage and retrieval of single ion excitation
is further demonstrated, without perturbing the emission characteristics. These
results promise new opportunities for controllable single photon sources and
efficient spin-photon interfaces.

Spontaneous emission is a fundamental out-of-equilibrium process in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations.
One way to modify these photon-mediated interactions is to alter the dipole radiation patterns of the emitter, e.g., by placing photonic crystals near them.
Our study delves into the interaction between these directional emission patterns and the aforementioned variables, revealing the untapped potential to fine-tune collective quantum optical phenomena.
