Quantum 6, 725 (2022). https://doi.org/10.22331/q-2022-05-30-725 Oblivious transfer is a cryptographic primitive where Alice has two bits and Bob wishes to learn some function of them. Ideally, Alice should not learn Bob’s desired function choice and […]
Quantum 6, 724 (2022). https://doi.org/10.22331/q-2022-05-30-724 We consider state redistribution of a “hybrid” information source that has both classical and quantum components. The sender transmits classical and quantum information at the same time to the receiver, […]
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 […]
Quantum 6, 716 (2022). https://doi.org/10.22331/q-2022-05-19-716 Certification of quantum devices received from unknown providers is a primary requirement before utilizing the devices for any information processing task. Here, we establish a protocol for certification of a […]
