Gaussian states have played an important role in the physics of continuous-variable
quantum systems. They are appealing for the experimental ease with which they can be …

In this work, we address fundamental limitations of quantum teleportation—the process of
transferring quantum information using classical communication and preshared …

The existence of fundamentally identical particles represents a foundational distinction
between classical and quantum mechanics. Because of their exchange symmetry, identical …

For indistinguishable itinerant particles subject to a superselection rule fixing their total
number, a portion of the entanglement entropy under a spatial bipartition of the ground state …

Quantum coherence, an essential feature of quantum mechanics allowing quantum
superposition of states, is a resource for quantum information processing. Coherence …

Quantitative control of spatial indistinguishability of identical subsystems as a direct quantum
resource at distant sites has not yet been experimentally proven. We design a setup capable …

Initialization of composite quantum systems into highly entangled states is usually a must to
enable their use for quantum technologies. However, unavoidable noise in the preparation …

This study proposes a procedure for the robust preparation of maximally entangled states of
identical fermionic qubits, studying the role played by particle statistics in the process. The …
