Ultranarrow linewidth room-temperature single-photon source from perovskite quantum dot embedded in optical microcavity

Amit R. Dhawan, Tristan Farrow, Ashley Marshall +5

Ultranarrow bandwidth single-photon sources operating at room-temperature are of vital importance for viable optical quantum technologies at scale, including quantum key distributi…

Detection of quantum phase transition in spin-1 chain through multipartite high-order correlations

Dongkeun Lee, Adel Sohbi, Wonmin Son

We design a Bell inequality that is violated by correlations obtained from the ground states of XXZ spin-1 chain with on site anisotropies at the region of phase transition. In ord…

Bell-type correlation at quantum phase transitions in spin-1 chain

Dongkeun Lee, Wonmin Son

For the identification of non-trivial quantum phase, we exploit a Bell-type correlation that is applied to the one-dimensional spin-1 XXZ chain. It is found that our generalization…

Noise-adaptive test of quantum correlations with quasiprobability functions

Seung-Woo Lee, Jaewan Kim, Wonmin Son

We introduce a method for testing quantum correlations in terms of quasiprobability functions in the presence of noise. We analyze the effects of measurement imperfection and therm…

Entropic Uncertainty Relations via Direct-Sum Majorization Relation for Generalized Measurements

Kyunghyun Baek, Hyunchul Nha, Wonmin Son

We derive an entropic uncertainty relation for generalized positive-operator-valued measure (POVM) measurements via a direct-sum majorization relation using Schur concavity of entr…

Efficient High-dimensional Quantum Key Distribution with Hybrid Encoding

Yonggi Jo, Hee Su Park, Seung-Woo Lee +1

We propose a schematic setup of quantum key distribution (QKD) with an improved secret key rate based on high-dimensional quantum states. Two degrees-of-freedom of a single photon,…
