Stealth quantum sensors unlock possibilities anywhere GPS doesn’t work

As commercial interest in quantum technologies accelerates, entrepreneurial minds at the University of Waterloo are not waiting for opportunities—they are creating them.

Among them is Alex Maierean (MMath ‘24), CEO of Phantom Photonics and part-time Ph.D. student at the Institute for Quantum Computing (IQC). Her startup is developing ultra-sensitive quantum sensors that can filter out background noise and detect the faintest signals, even down to a single photon—the smallest unit of light. This offers new levels of precision and stealth for industries operating in extreme environments, from the depths of the ocean to outer space.

Launched in 2023, the Velocity startup emerged from fundamental research at an IQC lab led by Dr. Thomas Jennewein, IQC affiliate and adjunct faculty in the Department of Physics and Astronomy. Today, the startup is based at Velocity where it has established a dedicated lab space to continue to develop its quantum sensor technology and build its core team.

Scientists Say a Major Quantum Computing Breakthrough Was Not What It Seemed

Replication is a cornerstone of science, yet even in the natural sciences, attempts to reproduce results do not always succeed. Quantum computing promises machines that can solve certain problems far beyond today’s computers, but it faces a stubborn obstacle: quantum information is extremely frag

This Quantum Breakthrough Could Change How Materials Are Made

Scientists have shown that it may be possible to transform materials simply by triggering internal quantum ripples rather than blasting them with intense light. Imagine being able to change what a material is capable of simply by shining light on it. That idea may sound like something out of s

What Is the Universe, Really? | Leonard Susskind

When we talk about the universe, we usually imagine space filled with galaxies, stars, and matter expanding endlessly in all directions. It feels natural to think of the universe as a vast container — a place where everything exists. But modern theoretical physics suggests that this picture may be deeply misleading.

In this video, we explore a more fundamental question: what is the universe really made of? Is it space? Matter? Energy? Or something far more abstract than our everyday intuition allows?

Drawing on ideas associated with Leonard Susskind, this long-form exploration challenges the assumption that the universe is a physical stage where reality takes place. Instead, physics increasingly points toward a universe defined not by objects and locations, but by information, relationships, and boundaries.

Black hole physics, quantum theory, and modern cosmology have forced scientists to rethink the foundations of reality. In some of the deepest descriptions of nature, space and time no longer appear as fundamental ingredients. What we experience as a three-dimensional universe may be an emergent structure — a convenient description rather than the true underlying reality.

Rather than focusing on equations, this video emphasizes intuition and conceptual understanding. Through thought experiments and simple analogies, we examine why the universe feels like a place, why that picture works so well at human scales, and why it may break down at the most fundamental level.

Quantum ‘alchemy’ made feasible with excitons

What if you could create new materials just by shining a light at them? To most, this sounds like science fiction or alchemy, but to physicists investigating the burgeoning field of Floquet engineering, this is the goal. With a periodic drive, like light, scientists can “dress up” the electronic structure of any material, altering its fundamental properties—such as turning a simple semiconductor into a superconductor.

While the theory of Floquet physics has been investigated since a bold proposal by Oka and Aoki in 2009, only a handful of experiments within the past decade have managed to demonstrate Floquet effects. And though these experiments show the feasibility of Floquet engineering, the field has been limited by the reliance on light, which requires very high intensities that almost vaporize the material while still only achieving moderate results.

But now, a diverse team of researchers from around the world, co-led by the Okinawa Institute of Science and Technology (OIST) and Stanford University have demonstrated a powerful new alternative approach to Floquet engineering by showing that excitons can produce Floquet effects much more efficiently than light. Their results are now published in Nature Physics.

Copenhagen Researchers state the Universe responds to our Actions Even Retroactively

The copenhagen interpretation & retroactivity. quantum mechanics basics:

Particles exist in a superposition of states until observed.

Measurement “collapses” the wave function into a definite outcome.

Retrocausality Debate:

Some physicists have explored whether quantum events can appear to be influenced by future measurements.

This is sometimes described as the universe “responding retroactively,” but it’s a controversial interpretation, not mainstream science.
