We propose and experimentally realize a novel versatile protocol that allows the quantum
state engineering of heralded optical coherent-state superpositions. This scheme relies on a …

The generation and manipulation of hybrid entanglement of light involving discrete-and
continuous-variable states have recently appeared as essential resources towards the …

Non-Gaussian states, and specifically the paradigmatic cat state, are well known to be very
sensitive to losses. When propagating through damping channels, these states quickly lose …

Quantum networks entangle remote nodes by distributing quantum states, which inevitably
suffer from decoherence while traversing quantum channels. Pertinent decoherence …

Einstein-Podolsky-Rosen steering is known to be a key resource for one-sided device-
independent quantum information protocols. Here we demonstrate steering using hybrid …

How can one detect entanglement between multiple optical paths sharing a single photon?
We address this question by proposing a scalable protocol, which only uses local …

Quantum computers, leveraging the principles of quantum mechanics, hold the potential to
surpass classical computers in numerous applications, with implications across various …

We discuss a simplified form of Stokes operators for quantum optical fields that involve the
known concept of binning. Behind polarization analyzer photon numbers (more generally …

We studied the effect of delocalized single-photon addition (DPA a ̂ 1†+ ei φ a ̂ 2†) on
two input modes containing four cases: two independent coherent states (CSs), two …

Single-photon entanglement (SPE) is important for quantum communication and quantum
information processing. However, SPE is sensitive to photon loss. In this paper, we discuss a …
