Periodic discretized continuous observables are neither continuous nor discrete
Thais L. Silva, Łukasz Rudnicki, Daniel S. Tasca +1
Most of the fundamental characteristics of quantum mechanics, such as non-locality and contextuality, are manifest in discrete, finite-dimensional systems. However, many quantum in…
Deterministic Generation of Large Fock States
M. Uria, P. Solano, C. Hermann-Avigliano
We present a protocol to deterministically prepare the electromagnetic field in a large photon number state. The field starts in a coherent state and, through resonant interaction…
Estimation of pure quantum states in high dimension at the limit of quantum accuracy through complex optimization and statistical inference
Leonardo Zambrano, Luciano Pereira, Sebastian Niklitschek +1
Quantum tomography has become a key tool for the assessment of quantum states, processes, and devices. This drives the search for tomographic methods that achieve greater accuracy.…
Boosting entanglement generation in down-conversion with incoherent illumination
Lucas Hutter, Gustavo Lima, Stephen P. Walborn
Entangled photons produced by spontaneous parametric down-conversion have been of paramount importance for our current understanding of quantum mechanics and advances in quantum in…
Collective radiation from distant emitters
Kanu Sinha, Alejandro González-Tudela, Yong Lu +1
Waveguides allow for direct coupling of emitters separated by large distances, offering a path to connect remote quantum systems. However, when facing the distances needed for prac…
Self-testing mutually unbiased bases in higher dimensions with space-division multiplexing optical fiber technology
Máté Farkas, Nayda Guerrero, Jaime Cariñe +2
In the device-independent quantum information approach, the implementation of a given task can be self-tested solely from the recorded statistics and without detailed models for th…
