Physicists develop a more sensitive microscope
Anyone who has taken a photo in a poorly lit restaurant or dim concert venue knows all too well the grainy, fuzzy outcomes of low-light imaging. Scientists trying to take images of biological specimens encounter the same ...

Possible way to test black hole information paradox in the lab
(Phys.org)—A pair of researchers, one with National Taiwan University, the other with École Polytechnique in France has come up with a way to test the idea of Hawking radiation and the information paradox in a lab setting. ...
Lab sets a new record for creating heralded photons
(Phys.org) —Entanglement, by general consensus of physicists, is the weirdest part of quantum science. To say that two particles, A and B, are entangled means that they are actually two parts of an inseparable quantum thing. ...

Quest for quantum Internet gets a boost with new technique for making entanglement
Traditional ways of producing entanglements, necessary for the development of any 'quantum internet' linking quantum computers, are not very well suited for fiber optic telecoms networks used by today's non-quantum internet. ...

Researchers entangle a single electron spin to a single photon in a quantum dot
(Phys.org)—Two teams working independently have succeeded in entangling a single electron spin with a single photon in a solid-state platform. Both teams describe their process and results in papers they've had published ...
