Every organism visible to the naked eye is a mass of genetically identical cells. Each of these multicellular creatures started as a single cell that divided countless times to produce its body. And while each […]
Quantum 8, 1334 (2024). https://doi.org/10.22331/q-2024-05-02-1334 The inherent degeneracy of quantum low-density parity-check codes poses a challenge to their decoding, as it significantly degrades the error-correction performance of classical message-passing decoders. To improve their performance, a […]
The journal Nature has published a research paper, “Probing single electrons across 300-mm spin qubit wafers,” demonstrating state-of-the-art uniformity, fidelity and measurement statistics of spin qubits. The industry-leading research opens the door for the mass […]
Quantum 8, 1333 (2024). https://doi.org/10.22331/q-2024-05-02-1333 Bell inequalities play a key role in certifying quantum properties for device-independent quantum information protocols. It is still a major challenge, however, to devise Bell inequalities tailored for an arbitrary […]
In the realm of condensed matter physics, few phenomena captivate physicists’ curiosity as much as Mott insulators. According to traditional theory, this odd class of materials should be capable of conducting electricity, yet they behave […]
Quantum 8, 1332 (2024). https://doi.org/10.22331/q-2024-05-02-1332 Losses in the transmission channel, which increase with distance, pose a major obstacle to photonics demonstrations of quantum nonlocality and its applications. Recently, Chaturvedi, Viola, and Pawlowski (CVP) [arXiv:2211.14231] introduced […]
Quantum 8, 1331 (2024). https://doi.org/10.22331/q-2024-05-02-1331 Quantum Wielandt’s inequality gives an optimal upper bound on the minimal length $k$ such that length-$k$ products of elements in a generating system span $M_n(mathbb{C})$. It is conjectured that $k$ […]
Insider Brief The 74th annual ECTC will take place May 28-31, 2024 at Denver’s Gaylord Rockies Resort & Convention Center. More than 1,500 scientists, engineers and businesspeople from more than 20 countries are expected to […]
Insider Brief Many important collaborations and partnerships were announced in April. These partnerships were spread out globally and across research and commercial domains, as well as industry agnostic. We also note the need for both […]
Quantum 8, 1330 (2024). https://doi.org/10.22331/q-2024-05-02-1330 Copy-protection allows a software distributor to encode a program in such a way that it can be evaluated on any input, yet it cannot be “pirated” – a notion that […]
