Quantum communication technology could one day enable an ultra-secure quantum internet, but so far creating the linkages in such a large network has proven challenging. A breakthrough in the ability to teleport quantum information could […]

Quantum 6, 723 (2022). https://doi.org/10.22331/q-2022-05-27-723 Non-unitary evolution can give rise to novel steady states classified by their entanglement properties. In this work, we aim to understand the effect of long-range hopping that decays with $r^{-alpha}$ […]
Quantum 6, 722 (2022). https://doi.org/10.22331/q-2022-05-27-722 We consider the distribution of high-dimensional entangled states to multiple parties via noisy channels and the subsequent probabilistic conversion of these states to desired target states using stochastic local operations […]
Quantum 6, 721 (2022). https://doi.org/10.22331/q-2022-05-24-721 We build on recent work by B. Brown (Sci. Adv. 6, eaay4929 (2020)) to develop and simulate an explicit recipe for a just-in-time decoding scheme in three 3D surface codes, […]
Quantum 6, 720 (2022). https://doi.org/10.22331/q-2022-05-24-720 Quantum machine learning (QML) has been identified as one of the key fields that could reap advantages from near-term quantum devices, next to optimization and quantum chemistry. Research in this […]
Quantum 6, 719 (2022). https://doi.org/10.22331/q-2022-05-24-719 The theoretical description of non-equilibrium Bose–Einstein condensate (BEC) is one of the main challenges in modern statistical physics and kinetics. The non-equilibrium nature of BEC makes it impossible to employ […]
Quantum 6, 718 (2022). https://doi.org/10.22331/q-2022-05-24-718 We present protocols for quantum key distribution in a prepare-and-measure setup with an asymmetric level of trust. While the device of the sender (Alice) is partially characterized, the receiver’s (Bob’s) […]
Quantum 6, 717 (2022). https://doi.org/10.22331/q-2022-05-24-717 In a Bell test, the set of observed probability distributions complying with the principle of local realism is fully characterized by Bell inequalities. Quantum theory allows for a violation of […]
As Moore’s Law begins to slow, the search is on for new ways to keep the exponential rise in processing speeds going. New research suggests that an exotic approach known as “lightwave electronics” could be […]
Nearly three billion years ago, oceanic mats of cyanobacteria, called blue-green algae, transformed Earth’s atmosphere by converting carbon dioxide into the oxygen we complex animals breath. In their time on the planet, they’ve survived five […]
