Worldwide, enormous efforts are directed toward the development of the so‐called quantum
internet. Turning this long‐sought‐after dream into reality is a great challenge that will …

The goal of integrated quantum photonics is to combine components for the generation,
manipulation, and detection of nonclassical light in a phase-stable and efficient platform …

The scaling of many photonic quantum information processing systems is ultimately limited
by the flux of quantum light throughout an integrated photonic circuit. Source brightness and …

On-chip single-photon sources are key components for integrated photonic quantum
technologies. Semiconductor quantum dots can exhibit near-ideal single-photon emission …

Scalable quantum technologies may be achieved by faithful conversion between matter
qubits and photonic qubits in integrated circuit geometries. Within this context, quantum dots …

The recent progress in integrated quantum optics has set the stage for the development of
an integrated platform for quantum information processing with photons, with potential …

A major step toward fully integrated quantum optics is the deterministic incorporation of high
quality single photon sources in on-chip optical circuits. We show a novel hybrid approach in …

The spin of an electron is a promising memory state and qubit. Connecting spin states that
are spatially far apart will enable quantum nodes and quantum networks based on the …

Quantum mechanics promises to have a strong impact on many aspects of research and
technology, improving classical analogues via purely quantum effects. A large variety of …

We demonstrate a new method to realize the population inversion of a single InGaAs/GaAs
quantum dot excited by a laser pulse tuned within the neutral exciton phonon sideband. In …
