Small registers of spin qubits in silicon can exhibit hour-long coherence times and exceeded
error-correction thresholds. However, their connection to larger quantum processors is an …

Silicon-carbide (SiC) is a promising platform for long-distance quantum information
transmission via single photons, offering long spin coherence qubits, excellent electronic …

Among the wealth of single fluorescent defects recently detected in silicon, the G center
catches interest for its telecom single-photon emission that could be coupled to a metastable …

Electronic defects in semiconductors form the basis for emerging quantum technologies, but
many defect centers are difficult to access at the single-particle level. A method for probing …

Color centers in the O-band (1260–1360 nm) are crucial for realizing long-coherence
quantum network nodes in memory-assisted quantum communications. However, only a …

Erbium-implanted silicon (Er: Si) holds promise for quantum networking, but the formation of
multiple Er centers poses a challenge. We show that the cubic center (Er-C) has C_2v or …

We develop a model describing long-range atom-atom interactions in a two-dimensional
periodic or aperiodic lattice of optical centers inside a solid-state host material. We consider …

Silicon-based quantum technologies have gained increasing attention due to their potential
for large-scale photonic integration, long spin coherence times, and compatibility with CMOS …
