Equal1 inaugurates its new center of excellence in Sherbrooke, Quebec, Canada, situated at the heart of Sherbrooke’s Quantum Innovation Zone. The center aims to cultivate talent in silicon spin qubits and promote collaborations with academic […]
IonQ, in collaboration with DESY (Deutsches Elektronen-Synchrotron), has demonstrated the potential of quantum computing to optimize airport flight gate operations. By leveraging IonQ Aria, the research aimed to address challenges such as minimizing traveler transit […]
Insider Brief QANplatform has announced that its quantum-resistant technology is being used for the first time by an EU country in the public sector. QANplatform’s technology protects government-owned cybersecurity infrastructure against quantum computing attacks. Store […]
Quantum 8, 1287 (2024). https://doi.org/10.22331/q-2024-03-14-1287 Variational Quantum Algorithms (VQAs) are often viewed as the best hope for near-term quantum advantage. However, recent studies have shown that noise can severely limit the trainability of VQAs, e.g., […]
Quantum 8, 1286 (2024). https://doi.org/10.22331/q-2024-03-14-1286 Recent advances have led towards first prototypes of quantum networks in which entanglement is distributed by sources producing bipartite entangled states. This raises the question of which states can be […]
Physicists have begun to explore the proton as if it were a subatomic planet. Cutaway maps display newfound details of the particle’s interior. The proton’s core features pressures more intense than in any other known […]
Researchers have unveiled the extraordinary behavior of weakly-bound three-atomic molecules, defying conventional understanding of quantum mechanics. In a study recently published in Nature Communications, a team of scientists from Bar-Ilan University in Israel, in collaboration […]
With your friends Bob and Charlie, you’re visiting far-off lands when you meet Kettu. He suggests you play a game to determine which extreme sport you should try. Beware, the rules of this game are […]
Quantum 8, 1285 (2024). https://doi.org/10.22331/q-2024-03-14-1285 Thouless pumping represents a powerful concept to probe quantized topological invariants in quantum systems. We explore this mechanism in a generalized Rice-Mele Fermi-Hubbard model characterized by the presence of competing […]
Quantum 8, 1284 (2024). https://doi.org/10.22331/q-2024-03-14-1284 We show how to find all $k$ marked elements in a list of size $N$ using the optimal number $O(sqrt{N k})$ of quantum queries and only a polylogarithmic overhead in […]
