Generation of non-classical correlations (or entanglement) between atoms,,,,,,, photons or
combinations thereof,, is at the heart of quantum information science. Of particular interest …

Abstract 'Schrödinger cat'states of light, defined as quantum superpositions of quasi-
classical coherent states, have recently emerged as an alternative to single-photon qubits …

Combining different physical systems in hybrid quantum circuits opens up novel possibilities
for quantum technologies. In quantum magnonics, quanta of collective excitation modes in a …

Quantum entanglement between distant qubits is an important feature of quantum networks.
Distribution of entanglement over long distances can be enabled through coherently …

We propose to create and stabilize long-lived macroscopic quantum superposition states in
atomic ensembles. We show that using a fully quantum parametric amplifier can cause the …

Accessing an ensemble of coherently interacting objects at the level of single quanta via a
proxy qubit is transformative in the investigations of emergent quantum phenomena. An …

Cavity magnon polaritons are mixed quasiparticles that arise from the strong coupling
between cavity photons and quantized magnons. Combining high-speed photons with long …

Multipartite entangled states are crucial for numerous applications in quantum information
science. However, the generation and verification of multipartite entanglement on fully …

We report dissipative magnon-photon coupling caused by the cavity Lenz effect, where the
magnons in a magnet induce a rf current in the cavity, leading to a cavity backaction that …

Realization of a quantum interface between stationary and flying qubits is a requirement for
long-distance quantum communication and distributed quantum computation. The prospects …
