An international group of researchers, led by Philip Walther of the University of Vienna, has made a significant advance in quantum technology by successfully demonstrating quantum interference among multiple single photons utilizing a unique resource-efficient platform.
Researchers investigated the feasibility of leveraging emerging quantum computers for radio astronomy calibration, focusing on redundant baseline calibration. They explored quantum annealers (QAs) and variational quantum linear solvers (VQLSs) for this task, considering both ideal and realistic settings.

This paper proposes that observers entangled with measurement possibilities cannot rely on standard predictions, extending the concept of measurement disturbance to the observers themselves. This argument challenges conventional interpretations of quantum mechanics and addresses the role of observers within the theory.
