Scientists achieve the first direct measurement of the quantum metric tensor in black phosphorus, advancing understanding of quantum states in solid materials. (Nanowerk News) Quantum distance refers ...

Imagine if we could use strong electromagnetic fields to manipulate the local properties of spacetime—this could have important ramifications in terms of science and engineering. Electromagnetism has ...

Some physicists believe that the metric tensor, a mathematical object describing the curvature of space-time, is simply a feature of space-time. Some physicists, most often mathematical physicists, ...

Quantum distance refers to a measure of quantum mechanical similarity between two quantum states. A quantum distance of one means that the two quantum states are the same, whereas a quantum distance ...
