New quantum microscopy trick quadruples microscope resolution

Three years after a team of Caltech scientists showed that pairs of entangled photons could double the resolution of a light microscope, the same lab has figured out a way to double down on that improvement. They have now achieved a fourfold resolution boost compared to a classical microscope, using a new optical design that sends one of the entangled photons through the microscope's optics three times rather than just once.

Amazon Researcher Claims Quantum Algorithm Could Challenge PQC Foundations

Insider Brief - A preliminary paper by an Amazon Web Services cryptographer presents a polynomial-time quantum algorithm for the Dihedral Coset Problem, a result that, if validated, could strengthen the theoretical case that quantum computers can efficiently solve lattice problems underlying much of today’s post-quantum cryptography.

X(2370) emerges as glueball-dominated particle in collider experiments

At the International Conference on High Energy Physics in Brazil, the BESIII Collaboration report that, after 15 years of sustained research, it identified the dominant constituent of the X(2370) as a pseudoscalar glueball with spin-parity quantum numbers of 0⁻⁺.
