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 […]
Niccolo Somaschi, CEO of Quandela, is interviewed by Yuval Boger. Niccolo describes the company’s approach to quantum computing, emphasizing the use of photonics and semiconductor technologies to manipulate photonic qubits. He highlights Quandela’s focus […]
Quantum teleportation isn’t just science fiction; it’s entirely real and happening in laboratories today. But teleporting quantum particles and information is a far cry from beaming people through space. In some ways, it’s even more […]
Quantum 8, 1283 (2024). https://doi.org/10.22331/q-2024-03-14-1283 It is useful to have a criterion for when the predictions of an operational theory should be considered classically explainable. Here we take the criterion to be that the theory […]
Insider Brief QuSecure released a product designed to fortify existing Cisco router-to-router communications against emerging quantum threats. QuProtect leverages advanced crypto-agile post-quantum cryptography. The product is meant to protect critical network infrastructures for enterprises, government, […]
Quantum 8, 1282 (2024). https://doi.org/10.22331/q-2024-03-14-1282 In this article, we present a novel approach to investigating entanglement in the context of quantum computing. Our methodology involves analyzing reduced density matrices at different stages of a quantum […]
