A team of physicists led by University of Rochester professor Regina Demina has made a groundbreaking discovery in the realm of quantum entanglement, an enigmatic phenomenon famously referred to by Albert Einstein as “spooky action at a distance.” Quantum entanglement involves the interlinked behavior of tiny particles that, once having interacted, can influence each other … Read more
Materials scientists and engineers aim to understand electron interactions and movements in novel materials to predict the behavior of devices made from these materials. Key questions include whether electrical current will flow easily, if there is a temperature at which the material becomes superconducting, and how long the quantum state of an electron spin will … Read more
Quantum information science is truly fascinating—pairs of tiny particles can be entangled such that an operation on either one will affect them both even if they are physically separated. A seemingly magical process called teleportation can share information between different far-flung quantum systems. These different systems can be coupled using quantum processes to form quantum … Read more
Named after an Italian theoretical physicist, Majoranas are complex quasiparticles that could be the key to building next-generation quantum computing systems. Most materials contain many electrons, each of which has a negative charge and a type of intrinsic quantum momentum known as spin. Interactions between electrons in some materials can produce emergent particles, or particles … Read more
The spin of the electron is nature’s perfect quantum bit, capable of extending the range of information storage beyond “one” or “zero.” Exploiting the electron’s spin degree of freedom (possible spin states) is a central goal of quantum information science. Recent progress by Lawrence Berkeley National Laboratory (Berkeley Lab) researchers Joseph Orenstein, Yue Sun, Jie … Read more
Gravity is a force that permeates our everyday lives, yet its true nature remains shrouded in mystery. Scientists grapple with the question of whether gravity’s essence aligns with Einstein’s geometric vision or adheres to the principles of quantum mechanics. This dilemma forms the backdrop of a new study published in Physical Review X, where researchers … Read more
Bartosz Regula, from the RIKEN Center for Quantum Computing, and Ludovico Lami, from the University of Amsterdam, have unveiled a groundbreaking discovery regarding the elusive nature of quantum entanglement. Their findings, rooted in probabilistic calculations, shed light on a long-hypothesized rule of entropy governing quantum entanglement, a phenomenon central to the potential power of future … Read more
Physicists have observed a novel quantum effect termed “hybrid topology” in a crystalline material. This finding opens up a new range of possibilities for the development of efficient materials and technologies for next-generation quantum science and engineering. The finding, published in Nature, came when Princeton scientists discovered that an elemental solid crystal made of arsenic … Read more
Research often unfolds as a multistage process. The solution to one question can spark several more, inspiring scientists to reach further and look at the larger problem from several different perspectives. Such projects can often be the catalyst for collaborations that leverage the expertise and capabilities of different teams and institutions as they grow. For … Read more
In the quest to develop quantum computers and networks, there are many components that are fundamentally different than those used today. Like a modern computer, each of these components has different constraints. However, it is currently unclear which materials can be used to construct those components for the transmission and storage of quantum information. In … Read more
