A few decades ago, quantum optics stood out as a new domain of physics by exhibiting
states of light with no classical equivalent. The first investigations concerned single photons …

Realizing a large-scale quantum computer requires hardware platforms that can
simultaneously achieve universality, scalability, and fault tolerance. As a viable pathway to …

Broadband multimode squeezers constitute a powerful quantum resource with promising
potential for different applications in quantum information technologies such as information …

Multimode nonclassical states of light are an essential resource in quantum computation
with continuous variables, for example, in cluster state computation. We report in this Letter …

Multimode quantum resources or states, in which quantum correlations are shared and
distributed among multiple parties, are important not only for fundamental tests of quantum …

Encoding quantum information in continuous variables is intrinsically faulty. Nevertheless,
redundant qubits can be used for error correction, as proposed by Gottesman et al.[Phys …

One-way quantum computing uses single-qubit projective measurements performed on a
cluster state (a highly entangled state of multiple qubits) in order to enact quantum gates …

We demonstrate an unseeded multimode four-wave-mixing process in hot Rb 85 vapor
using two pump beams of the same frequency that cross at a small angle. This results in the …

Broadband light sources play essential roles in diverse fields, such as high-capacity optical
communications, optical coherence tomography, optical spectroscopy and spectrograph …

An experimental scheme is proposed for building massively multipartite entangled states
using both the spatial and the frequency modes of an optical parametric oscillator. We …
