Description
Rare-earth ions are promising qubit candidates for quantum information processing due to their narrow homogeneous linewidth and long coherence times. Within this family, erbium owns the feature of transition wavelengths at the telecom C-band, allowing for long-distance transmission. Here, in an Er$^{3+}$-doped solid-state system, we first introduce a scheme for implementing universal quantum gates, where the high-fidelity two-qubit gates can be realized via the magnetic dipolar Ising interaction. Then, we will explore the potential utilization of their ion pairs. So far, we have demonstrated FTIR spectra to identify different Er$^{3+}$ pairs and built the laser system with microwave modulation to manipulate their electronuclear spin states.
