Researchers have presented the Quantum Phononic Links (QPLs) architecture, which is intended to transmit quantum information between distant qubits using phonons — quasiparticles that carry vibrational energy. One of the study’s first authors, Maksym Myronov, an associate professor at the University of Warwick in the United Kingdom, said that in this scheme phonons can serve as a “quantum bus.” As Live Science reports, this approach could potentially contribute to the creation of scalable quantum processors, including systems with more than one million qubits. The problem of communication between qubitsQubits find it difficult to exchange quantum information if they are not direct neighbors. In large quantum systems, communication between distant qubits is important, in particular, for applying quantum error-correction methods. QPLs are designed for long-distance communication between qubits via phonons. Unlike some other proposed methods, including surface acoustic waves, this approach, according to the authors’ assessment, does not require such a complex design or additional equipment.

Ancient mud reveals a surprising secret about Greenland’s ice - Earth.com
Mud from a fjord shows an Atlantic air pattern brought wetter, colder spells to southern Greenland, a clue to how its ice may fare. Greenland’s ice is shrinking as the planet warms. But in the island’s southwest, rainfall and snowfall have been influenced by the same North Atlantic air-pressure pattern for at least 5,000 years. When that pattern tipped one way, the region turned wetter and colder. The record comes from mud on the floor of a Greenland fjord, and it suggests snowfall, not only temperature, shaped how the area’s ice grew and shrank. It doesn’t yet show how glaciers there will respond to the warming ahead. Johan Faust, a researcher at MARUM, the Center for Marine Environmental Sciences at the University of Bremen in Germany, led the work with colleagues in Germany, Norway, Denmark and Canada. A seesaw in the airThe pattern is called the North Atlantic Oscillation. It’s the difference in air pressure between a low that sits near Iceland and a high near the Azores, and it’s strongest in winter. When that difference is large, the pattern is in its positive phase. Northwestern Europe and southwestern Greenland both get more rain and snow.
