Quantum 9, 1952 (2025). https://doi.org/10.22331/q-2025-12-18-1952 Current quantum technologies are at the cusp of becoming useful, but still face formidable obstacles such as noise. Noise severely limits the ability to scale quantum devices to the point […]
In order to scale quantum computers, more qubits must be added and interconnected. However, prior attempts to do this have resulted in a loss of connection quality, or fidelity. But, a new study published in […]
Mathematics is, at its core, an art. Like painters, musicians or writers, mathematicians create and explore new worlds. They test, and then push past, the limits of their imagination. They engage with thousands of years […]
Insider Brief Researchers at Silicon Quantum Computing demonstrated an 11-qubit silicon-based quantum processor that links multiple qubit registers while maintaining error rates compatible with fault-tolerant operation. The study shows that nuclear spin qubits in silicon […]
Insider Brief Enlightra has raised $15 million to develop chip-scale multiwavelength laser technology aimed at replacing copper interconnects in AI and data center infrastructure. Its silicon-photonics-based lasers enable high-bandwidth, energy-efficient optical links between GPUs and […]
Like their conventional counterparts, quantum computers can also break down. They can sometimes lose the atoms they manipulate to function, which can stop calculations dead in their tracks. But scientists at the US-based firm Atom […]
Application deadline: Saturday, January 31, 2026 Employer web page: https://upol.cz/en Job type: PostDoc Do you want to contribute to the development of the quantum internet? Do you possess a strong background in theoretical quantum optics, […]
Quantum 9, 1951 (2025). https://doi.org/10.22331/q-2025-12-18-1951 We present a novel approach to quantizing Markov chains. The approach is based on the Markov chain coupling method, which is frequently used to prove fast mixing. Given a particular […]
Researchers from the University of Innsbruck, the Collège de France, and the Université Libre de Bruxelles have developed a simple yet powerful method to reveal anyons—exotic quantum particles that are neither bosons nor fermions—in one-dimensional […]
After a decade of painstaking measurements, scientists have delivered a major plot twist in particle physics: a long-hypothesized “mystery particle” likely doesn’t exist. Using the MicroBooNE experiment at Fermilab, researchers analyzed neutrinos from two powerful […]
