A new entanglement-enhanced quantum sensing scheme
Over the past decades, quantum scientists have introduced various technologies that operate leveraging quantum mechanical effects, including quantum sensors, computers and memory devices. Most of these technologies leverage entanglement, a quantum phenomenon via which two or more particles become intrinsically linked and share a unified quantum state, irrespective of the distance between them.
Introduction to Quantum Electrodynamics (QED)
It’s now time to dig into quantum field theories with considerably more rigor than earlier in the series. First up is quantum electrodynamics, or QED. This was the first successful QFT, combining quantum mechanics and special relativity. Let’s learn what this model is all about, and how to do math with Feynman diagrams.

The Physicist Who Proved Entropy = Gravity
What if gravity is not fundamental but emerges from quantum entanglement? In this episode, physicist Ted Jacobson reveals how Einstein’s equations can be derived from thermodynamic principles of the quantum vacuum, reshaping our understanding of space, time, and gravity itself.

Gravitational waves leave imprints on light emitted by atoms, theoretical study predicts
Gravitational waves are ripples in spacetime produced by violent cosmic events, such as the merging of black holes. So far, direct detections have relied on measuring tiny distance changes over kilometer-scale instruments. In a new theoretical study published in Physical Review Letters, researchers at Stockholm University, Nordita, and the University of Tübingen propose an unconventional approach: tracking how gravitational waves reshape the light emitted by atoms. The work describes a possible detection route, but an experimental demonstration remains for the future.
When atoms are excited, they naturally relax by emitting light at a characteristic frequency—a quantum process known as spontaneous emission. This happens through their interaction with the quantum electromagnetic field.
“Gravitational waves modulate the quantum field, which in turn affects spontaneous emission,” said Jerzy Paczos, a Ph.D. student at Stockholm University. “This modulation can shift the frequencies of emitted photons compared with the no-wave case.”
Inside the Gigantic Universe
Physicist Jim Al-Khalili explores the incomprehensible scale of the universe. A cosmic journey into the laws of gravity, relativity, and the formation of supergalaxies. Discover how the largest structures shape our understanding of the cosmos itself.
Director: Tim Usborne.
Writers: Jim Al-Khalili, Tim Usborne.
Stars: Prof. Jim Al-Khalili (Physicist, Presenter)
Genre: Science Documentary, Physics, Cosmology.
Country: United Kingdom.
Language: English Also Known As: Secrets of Size: Going Big (BBC)
Release Date: 2022
Filming Location: United Kingdom / Various International Locations.
Synopsis:
In this second episode of the fascinating series Secrets of Size, Professor Jim Al-Khalili takes us on a cosmic journey into the immensity, exploring the largest scale of the universe.
We leave behind the quantum realm to focus on the forces that govern the largest structures: gravity and relativity. Al-Khalili explains how these laws shape the existence of galaxies, galaxy clusters, and the immense supergalaxies.
The episode reveals the incomprehensible scale of the cosmos, where time and space are distorted, and how the study of these giants allows us to understand the origin, evolution, and perhaps the ultimate destiny of the universe itself.

A century after the birth of quantum mechanics, physicists still argue about what the theory is really describing. Does the wave function represent something real, or just our knowledge? Why does “measurement” appear in the laws of nature at all?
Sean Carroll reveals how quantum mechanics solved one set of problems while creating a deeper one.
