Photon pairs are more sensitive to rotations than single photons

Quantum states of light have enabled novel optical sensing schemes, e.g., for measuring distance or position, with precisions impossible to achieve with classical light sources such as lasers. The field of quantum metrology ...

How to test the limits of quantum mechanics

Researchers from Imperial College London and Lancaster University have suggested a new approach to test the limits of applicability of quantum mechanics.

Complex shapes of photons to boost future quantum technologies

As the digital revolution has now become mainstream, quantum computing and quantum communication are rising in the consciousness of the field. The enhanced measurement technologies enabled by quantum phenomena, and the possibility ...

Multiparty entanglement: When everything is connected

Entanglement is an ubiquitous concept in modern physics research: it occurs in subjects ranging from quantum gravity to quantum computing. In a publication that appeared in Physical Review Letters last week, UvA-IoP physicist ...

Great progress for electronic gadgets of the future

Researchers at the Norwegian University of Science and Technology (NTNU) have found a completely new method to check the electronic properties of oxide materials. This opens the door to even tinier components and perhaps ...
