Abstract

We study the coherence times and perform manipulations on the lowest-energy states of trivalent cerium ion in calcium tungstate crystal. We find the phase memory time reaching 14.2 ${\mu}$ s and the time of coherent manipulations reaching 0.3 ${\mu}$ s in the low-temperature limit, the latter can potentially be elongated by using the rotation angle and off-resonance error correction schemes.
