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 …

More than 80 years have passed since the first publication on entangled quantum states.
Over this period, the concept of spookily interacting quantum states became an emerging …

Semiconductor quantum dots in cavities are promising single-photon sources. Here, we
present a path to deterministic operation, by harnessing the intrinsic linear dipole in a …

The quest for the perfect single-photon source includes finding the optimal protocol for
exciting the quantum emitter. Coherent optical excitation was, up until now, achieved by …

Single photons are attractive candidates of quantum bits (qubits) for quantum computation
and are the best messengers in quantum networks. Future scalable, fault-tolerant photonic …

The energy states in semiconductor quantum dots are discrete as in atoms, and quantum
states can be coherently controlled with resonant laser pulses. Long coherence times allow …

Resonantly driven quantum emitters offer a very promising route to obtain highly coherent
sources of single photons required for applications in quantum information processing (QIP) …

To coherently control a few-level quantum emitter, typically pulses with an energy resonant
to the transition energy are applied, making use of the Rabi mechanism, while a single off …

We review distinct features arising from the unique nature of the carrier-phonon coupling in
self-assembled semiconductor quantum dots. Because of the discrete electronic energy …

It is demonstrated how the exciton and the biexciton state of a quantum dot can be prepared
with high fidelity on a picosecond time scale by driving the dot with a strong laser pulse that …
