Insider Brief Scientists report they adapted a device called a microwave circulator for use in quantum computers. The ability to precisely tune the degree of nonreciprocity could serve as an important tool to have in […]
Researchers have succeeded in conducting an almost perfect quantum teleportation despite the presence of noise that usually disrupts the transfer of quantum state. The results have been published in the journal Science Advances. Click to […]
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 […]
