• Abstract summary: coherent excitation of an optically active spin system is one of the key elements in the engineering of a spin-photon interface. In this work, we use the novel SUPER scheme, employing nonresonant ultrashort optical pulses, to coherently control the main optical transition of a tin-vacancy color center in diamond.

• Abstract: The coherent excitation of an optically active spin system is one of the key elements in the engineering of a spin-photon interface. In this work, we use the novel SUPER scheme, employing nonresonant ultrashort optical pulses, to coherently control the main optical transition of a tin-vacancy color center in diamond, a promising emitter that can both be utilized as a quantum memory and a single-photon source. Furthermore, we implement a subpicosecond control scheme using resonant pulses for achieving record short quantum gates applied to diamond color centers. The employed ultrafast quantum gates open up a new regime of quantum information processing with solid-state color centers, eventually enabling multi-gate operations with the optical qubit and efficient spectral filtering of the excitation laser from deterministically prepared coherent photons.

  We present a quantum photonic interface based on a single Tin-Vacancy center in a micrometer-thin diamond membrane coupled to a tunable open microcavity. We observe a transmission dip of 50 % for low incident photon number per Purcell-reduced excited state lifetime, while the dip disappears as the emitter is saturated with higher photon number. This work establishes a versatile and tunable platform for advanced quantum optics experiments and proof-of-principle demonstrations towards quantum networking with solid-state qubits.

  Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols.

We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
