A New Quantum Phase Discovered in Atomically Thin Hafnium Telluride

Quantum physics is the study of the nature and behavior of matter and energy at the smallest scales. It reveals some of the most fascinating and mysterious phenomena in the universe, such as superconductivity, quantum entanglement, and quantum tunneling. One of these phenomena is the excitonic...

Time crystals: A new state of matter that defies physics

You may have heard of crystals, such as diamonds or quartz, that have a regular and repeating pattern of atoms in space. These patterns give crystals their beautiful shapes and properties. But what if there was a way to create crystals that also have a...

A step towards quantum gravity

According to Einstein's general theory of relativity, gravity arises when a massive object distorts the fabric of spacetime in the same way that a ball sinks into a piece of stretched cloth. Solving Einstein's equations with quantities that apply across all space and time...

First experiment of quantum contextuality ‘without loopholes’

Contextuality is essential to explain the power of quantum computers. It is also essential for the security of quantum communications. The study was published in the journal Science Advances. Scientists have used a game to explain this. Sergio and Mario show us their hands with their...

Entanglement unlocks scaling for quantum machine learning

The field of machine learning on quantum computers got a boost from new research. The research removed a potential roadblock to the practical implementation of quantum neural networks. Theorists had previously thought an exponentially large training set would be required to train a quantum...

Study redefines what information is important in quantum measurements

Korea Institute of Science and Technology scientists have tried to capture the interplay between different types of information that are important at the time of collecting quantum measurements. These are information gain, disturbance and reversibility. The study has been published in Physical Review Letters....
