Like the imbalance of matter and antimatter, the emergence of life based on molecules with a like chirality as opposed to their mirror opposites has long puzzled scientists.  David Armstrong studies a phenomenon that is ubiquitous in nature, yet only a few non-scientists know what it is.  Physicists at Johannes Gutenberg University Mainz (JGU) have recently succeeded in observing parity violation in ytterbium atoms with different numbers of neutrons.  Exploring the mystery of molecular handedness in nature, scientists have proposed a new experimental scheme to create custom-made mirror molecules for analysis.  Identifying right-handed and left-handed molecules is a crucial step for many applications in chemistry and pharmaceutics.  A team of researchers from several institutions in Japan has described a physical system that can be described as existing above "absolute hot" and also below absolute zero.  A silicon-based quantum computing device could be closer than ever due to a new experimental device that demonstrates the potential to use light as a messenger to connect quantum bits of information-known as qubits-that are not immediately adjacent to each other.  Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information.  Theoretical physicists propose to use negative interference to control heat flow in quantum devices.  Particle physicists are studying ways to harness the power of the quantum realm to further their research.  A fundamental barrier to scaling quantum computing machines is "qubit interference." In new research published in Science Advances, engineers and physicists from HYPERLINK "https://www.rigetti.com/" Rigetti Computing describe a breakthrough that can expand the size of practical quantum processors by reducing interference.  The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers.
