Abstract: In 2022, the Royal Swedish Academy of Sciences recognized groundbreaking experiments demonstrating that quantum entanglement is an intrinsic feature of the physical world, with far-reaching implications for secure communication, quantum computing, and advanced sensing technologies. In this talk, we will explore the science and technology behind the “spooky action at a distance” that troubled Albert Einstein and was later formalized through John Bell’s famous inequality. We will focus on the development of quantum-entangled probes designed to reveal the intrinsic entanglement of matter—a discipline we refer to as Quantum Entanglement Microscopy. We present experimental realizations of entangled neutron beams, in which individual neutrons are entangled in their spin, trajectory, and energy degrees of freedom. By carefully tuning the entanglement and coherence of the probe, it becomes possible to directly access and characterize the entanglement properties of the target material. Our theoretical framework further supports the idea that entangled beams of quantum particles—including neutrons, X-rays, and photon pairs—can serve as versatile and powerful tools for scientific discovery.
