To become more pervasive in daily life, quantum technology needs to better detect single particles of light, called photons, carrying quantum information. The problem is that each photon is a very weak signal, making it difficult for measurement devices to efficiently detect them. Purdue University engineers have proposed a new quantum resource that could help design the next generation of single-photon detectors.

Quantum causality is an emerging field of study which has the potential to greatly advance our understanding of quantum systems. In this paper, we put forth a theoretical framework for merging quantum information science and causal inference by exploiting entropic principles. For this purpose, we...
