Achieving Millisecond Coherence in Quantum Qubits Through Energy Loss Reduction

Scientists from Yale University and the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have developed a systematic approach to understanding how energy is lost from the materials that make up qubits. Energy loss inhibits the performance of these quantum computer building blocks, so determining its sources -- and adjusting the materials as necessary -- can help bring researchers closer to designing quantum computers that could revolutionize several scientific fields.

Chaotic Quantum Behavior of Neutrinos in Core-Collapse Supernovae Revealed Through Entanglement

Neutrinos can change their identities or "flavors" when they interact. Researchers recently found that the neutrinos in a very dense environment such as a core collapse supernova can develop strong correlations through mutual interactions. This means that over time, neutrinos with different initial flavors reach a similar equilibrium flavor and energy distribution.
