Quantum 6, 694 (2022). https://doi.org/10.22331/q-2022-04-21-694 Path integrals constitute powerful representations for both quantum and stochastic dynamics. Yet despite many decades of intensive studies, there is no consensus on how to formulate them for dynamics in […]
Quantum 6, 693 (2022). https://doi.org/10.22331/q-2022-04-21-693 We introduce a simple construction of boundary conditions for the honeycomb code [1] that uses only pairwise checks and allows parallelogram geometries at the cost of modifying the bulk measurement […]
Although development activities for programmable neutral atom quantum computers started later than developments in superconducting and ion trap quantum computers, some people see a lot of future potential in this technology due to its long […]
We’ve heard a lot about the immune system over the last couple of years of the COVID-19 pandemic, but of course our immune system fights off much more than the coronavirus. And while the immune […]
In 1989, the renowned physicist John Wheeler, popularizer of the term “black hole,” proposed a radical new way to think about the universe. Quantum particles may shape-shift and disappear, but we can always count on […]
Rydberg atoms are excited atoms that contain one or more electrons with a high principal quantum number. Due to their large size, long-range dipole-dipole interactions and strong coupling to external fields, these atoms have proved […]
A team of researchers at Tsinghua University in China, has broken the distance record for quantum secure direct communication (QSDC) by sending information using their protocol a distance of 102.2 km. In their paper published […]
Researchers have discovered that light—in the form of a laser—can trigger a form of magnetism in a normally nonmagnetic material. This magnetism centers on the behavior of electrons. These subatomic particles have an electronic property […]
Paderborn University is a high-performance and internationally oriented university with approximately 20,000 students. Within interdisciplinary teams, we undertake forward-looking research, design innovative teaching concepts and actively transfer knowledge into society. As an important research and […]
