Laser-cooled atomic gases, gases of atoms chilled to temperatures around absolute zero using laser technologies, have proved to be versatile physical platforms to study and control quantum phenomena. When these atomic gases interact with light inside an optical cavity (i.e., a structure designed to trap and enhance light), they can give rise to effects that can be leveraged to realize quantum sensing or simulate complex quantum systems.
Using atomic gases loaded in optical cavities, physicists have observed various intriguing effects, including self-organization phase transitions, characterized by the spontaneous arrangement of the gas atoms into ordered patterns, lasing and the preservation of quantum coherence. Generally, however, these effects are only observed for short times, as new atoms need to be reloaded in the cavity for them to be produced again.
Researchers at JILA, a joint research institute of the University of Colorado-Boulder and the National Institute of Standards and Technology, recently demonstrated continuous lasing that lasted hours using laser-cooled strontium-88 (88 Sr) atoms loaded into a ring (i.e., circular) optical cavity. Their paper, published in Nature Physics, could open new possibilities for the development of ultra-quiet lasers, as well as quantum computers and sensing technologies.
But one key challenge stands in the way: speed.
To be reliable, quantum computers must perform calculations and error corrections before their fragile quantum bits, or qubits, lose coherence.
Now, MIT researchers have built a new superconducting circuit that could dramatically speed up this process.
What if gravity isn’t a force, but a computation? In this episode, we explore Dr. Melvin Vopson’s groundbreaking theory that gravity emerges from the universe’s effort to compress and optimize information. Discover how this idea connects with simulation theory, quantum physics, and the future of reality.

Four physicists at the Hebrew University of Jerusalem, in Israel, have unraveled the mechanical process behind the growth of roses as they blossom into their unique shape. In their study published in the journal Science, Yafei Zhang, Omri Cohen, Michael Moshe and Eran Sharon adopted a multipronged approach to learn the secrets behind rose blossom growth. Qinghao Cui and Lishuai Jin, with the University of Hong Kong have published a Perspective piece in the same journal issue outlining the work.
Roses have been prized for their beauty and sweet aromas for thousands of years, but until now, the mechanics behind rose growth have not been explored. To gain a better understanding of the process, the research team undertook a three-pronged approach. First, they conducted a theoretical analysis of the process. Then they created computer models to simulate the ways the flowers might grow and bloom; finally, they created real-world bendable plastic disks to simulate petals and the possible ways they could grow given the constraints of real roses.
They found that the shape of the petals is strongly influenced by the frustration known as the Mainardi-Codazzi-Peterson incompatibility, in which geometric compatibility conditions inherent on a surface made of a particular material are violated, leading to forces that generate rolling and sharp edges.
Photographer Stephen Voss has been working on a project about data centers and recently travelled to Abilene, Texas to document the first data center built as part of the Stargate Project. When completed, it will be the largest data center in the world. Here’s a short drone video he took of the project:
“The place was mesmerizing and deeply unsettling,” Voss told me over email. “When finished, it’ll have the power demands of a mid-sized city and is on a piece of land that’s the size of Central Park.”
A new MIT-designed circuit achieves record-setting nonlinear coupling, allowing quantum operations to occur dramatically faster.
The heart of this advance is the “quarton coupler,” which boosts both light-matter and matter-matter interactions. This progress could lead to quicker quantum readouts, crucial for error correction and computation fidelity.
