- Abstract summary: We present the Purcell-enhanced detection of single solid-state ions in erbium-doped nanoparticles placed in a fiber cavity.
The ions are confined in a volume two orders of magnitude smaller than in previous realizations, increasing the probability of finding ions separated only by a few nanometers.
Our fully fiber-integrated system is an important step towards the realization of the initially envisioned quantum hardware.

- Abstract: Many quantum information protocols require the storage and manipulation of
information over long times, and its exchange between nodes of a quantum
network across long distances. Implementing these protocols requires an
advanced quantum hardware, featuring, for example, a register of long-lived and
interacting qubits with an efficient optical interface in the telecommunication
band. Here we present the Purcell-enhanced detection of single solid-state ions
in erbium-doped nanoparticles placed in a fiber cavity, emitting photons at
1536 nm. The open-access design of the cavity allows for complete tunability
both in space and frequency, selecting individual particles and ions. The ions
are confined in a volume two orders of magnitude smaller than in previous
realizations, increasing the probability of finding ions separated only by a
few nanometers which could then interact. We report the detection of individual
spectral features presenting saturation of the emission count rate and
linewidth, as expected for two-level systems. We also report an uncorrected
$g^{(2)} \left ( 0 \right )$ of 0.24(5) for the emitted field, confirming the
presence of a single emitter. Our fully fiber-integrated system is an important
step towards the realization of the initially envisioned quantum hardware.
