New method enables quantum simulations on larger systems

Through randomly selected measurements, Austrian physicists can now determine the quantum entanglement of many-particle systems. With the newly developed method, quantum simulations can be extended to a larger number of quantum ...

Optical toric code platform sets new record

Anyons form the basis for topological quantum computation and error correction, where the topological aspect of anyonic braiding is one of the important features that gives rise to fault tolerance. More qubits to control ...

Entangling photons of different colors

Some of the most advanced communication systems now under development rely on the properties of quantum science to store and transport information. However, researchers designing quantum communication systems that rely on ...

Our 2.5-million-year obsession with stuff

Decluttering, spring cleaning or watching an episode of a home makeover television show often leads to the question: Why do we have so much junk? According to Stanford archaeologist Ian Hodder, our love for stuff dates back ...

Quantifying how much quantum information can be eavesdropped

Summary The most basic type of quantum information processing is quantum entanglement. In a new study published in EPJ B, Zhaonan Zhang from Shaanxi Normal University, Xi'an, China, and colleagues have provided a much finer ...

Using quantum entanglement to study proteins

For the first time, a University of Michigan chemist has used quantum entanglement to examine protein structures, a process that requires only a very small number of photons of light.
