Quantum 9, 1931 (2025). https://doi.org/10.22331/q-2025-12-05-1931 To achieve quantum fault tolerance with lower overhead, quantum low-density parity-check (QLDPC) codes have emerged as a promising alternative to topological codes such as the surface code, offering higher code […]
Insider Brief Researchers led by Paderborn University report the first successful teleportation of a photon’s polarization state between two spatially separated quantum dots. The team demonstrated quantum teleportation over a 270-meter free-space link, achieving an […]
Quantum 9, 1930 (2025). https://doi.org/10.22331/q-2025-12-05-1930 Nonlocal tests on multi-partite quantum correlations form the basis of protocols that certify randomness in a device-independent (DI) way. Such correlations admit a rich structure, making the task of choosing […]
Insider Brief Japanese researchers demonstrated a cloud-operated trapped-ion qubit system, marking what may be the country’s first automated ion-trap computing platform accessible over the internet. The Osaka University team integrated an ytterbium ion trap, automated […]
Quantum 9, 1929 (2025). https://doi.org/10.22331/q-2025-12-05-1929 Quantum resource theories provide a mathematically rigorous way of understanding the nature of various quantum resources. An important problem in any quantum resource theory is to determine how quantum states […]
Insider Brief A new Science article argues that quantum technology has reached a turning point similar to the dawn of the transistor era, with early systems now emerging from research labs into real-world use. The […]
Insider Brief Mesa Quantum is using Elevate Quantum’s shared-use Commercialization Lab to test and advance next-generation PNT technologies without building its own specialized infrastructure. Access to equipment such as the Vescent Optical Atomic Clock enables […]
SEEQC, a digital quantum computing company, has announced a manufacturing partnership with Taiwan’s Industrial Technology Research Institute (ITRI) to construct a state-of-the-art process line dedicated to manufacturing SEEQC’s proprietary Single Flux Quantum (SFQ) superconducting control […]
Florida Quantum, a new statewide initiative, has announced its formation to organize, attract, and accelerate quantum innovation and investment across the state. The initiative was co-led by Matt Cimaglia of Quantum Coast Capital and Tony […]
SEALSQ Corp (NASDAQ: LAES), a provider of post-quantum semiconductor technologies, has announced a strategic investment in EeroQ, a U.S.-based quantum chip design company. This investment aligns with SEALSQ’s “Quantum Made in USA” industrial strategy and […]
