- Abstract summary: We characterize a high-density sample of negatively charged silicon-vacancy (SiV$-$) centers in diamond using collinear optical multidimensional coherent spectroscopy.
By comparing the results of complementary signal detection schemes, we identify a hidden population of ceSiV- centers that is not typically observed in photoluminescence.

- Abstract: We characterize a high-density sample of negatively charged silicon-vacancy
(SiV$^-$) centers in diamond using collinear optical multidimensional coherent
spectroscopy. By comparing the results of complementary signal detection
schemes, we identify a hidden population of \ce{SiV^-} centers that is not
typically observed in photoluminescence, and which exhibits significant
spectral inhomogeneity and extended electronic $T_2$ times. The phenomenon is
likely caused by strain, indicating a potential mechanism for controlling
electric coherence in color-center-based quantum devices.

The G center is a unique defect where the standard Born-Oppenheimer approximation breaks down.
The impact of this atomic reconfiguration on the photoluminescence properties of G centers is still largely unknown.
We show that single G defects in silicon exhibit a multipolar emission and zero-phonon line fine structures with splittings up to $sim1$ meV.

We leverage a multi-dimensional and multi-sensor analysis of spectral diffusion to investigate the dynamics of carriers in charge traps surrounding color center clusters in diamond.
Our results can be generalized to other color centers and open intriguing opportunities for the microscopic characterization of photo-carrier dynamics in semiconductors.

We show that by coupling nitrogen-vacancy centers in a diamond membrane to a high-finesse microcavity, few, incoherent, inhomogeneous, and spatially separated emitters can enter the regime of collective emission.
We observe a super-linear power dependence of the emission rate as a hallmark of collective emission.

Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement.
We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

Hybrid quantum systems in the ultrastrong, and even more in the deep-strong, coupling regimes can exhibit exotic physical phenomena.
We experimentally observe the parity symmetry breaking of an ancillary Xmon artificial atom induced by the field of a lumped-element superconducting resonator.
This result opens a way to experimentally explore the novel quantum-vacuum effects emerging in the deep-strong coupling regime.

Electromagnetically induced transparency (EIT) is a phenomenon that can provide strong and robust interfacing between optical signals and quantum coherence of electronic spins.
We show that EIT can be established with high visibility also in this material platform upon careful design of the measurement geometry.
Our work provides an understanding of EIT in multi-level systems with significant inhomogeneities, and our considerations are valid for a wide array of defects in semiconductors.
