Photon-photon scattering in vacuum is extremely weak. However, strong effective
interactions between single photons can be realized by employing strong light-matter …

Distributed quantum networks will allow users to perform tasks and to interact in ways which
are not possible with present-day technology. Their implementation is a key challenge for …

We report phase-programmable Gaussian boson sampling (GBS) which produces up to 113
photon detection events out of a 144-mode photonic circuit. A new high-brightness and …

We develop a geometric approach to operator growth and Krylov complexity in many-body
quantum systems governed by symmetries. We start by showing a direct link between a …

We propose an all-optical approach to achieve optical nonreciprocity on a chip by quantum
squeezing one of two coupled resonator modes. By parametric pumping a χ (2)-nonlinear …

We propose a method for the fast generation of nonclassical ground states of the Rabi
model in the ultrastrong and deep-strong coupling regimes via the shortcuts-to-adiabatic …

Entanglement of light and multiple vibrations is a key resource for multichannel quantum
information processing and memory. However, entanglement generation is generally …

Collective strong coupling between a disordered ensemble of N localized molecular
vibrations and a resonant optical cavity mode gives rise to two polariton and N-1≫ 2 dark …

We introduce a second quantization scheme based on quasinormal modes, which are the
dissipative modes of leaky optical cavities and plasmonic resonators with complex …

Conventional spectroscopy uses classical light to detect matter properties through the
variation of its response with frequencies or time delays. Quantum light opens up new …
