Revealing high-dimensional entanglement through symmetry
Jayden Webster, Florian Kanitschar, Emanuele Polino +5
Photons encoded in discrete time bins can be routinely prepared in temporal superposition states, enabling high-dimensional entanglement and enhanced quantum communication rates. H…
Rigorous no-go theorems for heralded linear-optical state generation tasks
Deepesh Singh, Ryan J. Marshman, Luis Villegas-Aguilar +2
A major challenge in photonic quantum technologies is developing strategies to prepare suitable discrete-variable quantum states using simple input states, linear optics, and auxil…
Detection-loophole-free nonlocality in the simplest scenario
Nandana T Raveendranath, Travis J. Baker, Emanuele Polino +7
Loophole-free quantum nonlocality often demands experiments with high complexity (defined by all parties' settings and outcomes) and multiple efficient detectors. Here, we identify…
Heralded generation of a three-mode NOON state
Sukhjit P. Singh, Elnaz Bazzazi, Diego N. Bernal-GarcÃa +8
Entangled states of photons form the foundation of quantum communication, computation, and metrology. Yet their generation remains fundamentally constrained: in the absence of intr…
Near-unity quantum interference of transverse spatial modes in an ultra-compact inverse-designed photonic device
Jamika Ann Roque, Daniel Peace, Simon White +6
The transverse spatial mode of photons is an untapped resource for scaling up integrated photonic quantum computing. To be practically useful for improving scalability, reliable an…
Heralded generation of entanglement with photons
Imogen Forbes, Farzad Ghafari, Edward C. R. Deacon +6
Entangled states of photons form the backbone of many quantum technologies. Due to the lack of effective photon-photon interactions, the generation of these states is typically pro…
