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.

Probing quantum physics on a macroscopic scale

Why does quantum mechanics work so well for microscopic objects, yet macroscopic objects are described by classical physics? This question has bothered physicists since the development of quantum theory more than 100 years ...

Griffith precision measurement takes it to the limit

Griffith University researchers have demonstrated a procedure for making precise measurements of speed, acceleration, material properties and even gravity waves possible, approaching the ultimate sensitivity allowed by laws ...

New method could lead to more powerful quantum sensors

As quantum technology continues to come into its own, investment is happening on a global scale. Soon, we could see improvements in machine learning models, financial risk assessment, efficiency of chemical catalysts and ...
