While playing with the IBM Q experience in some of my recent posts, we have seen that real qubits are subject to geometric restrictions – two-qubit gates cannot involve arbitrary qubits, but …

This is how a black hole can exist in both two dimensions and three dimensions at the same time.

Mind=blown.

Quantum processes are helpful to know about when we hear a gimcrack new theory that dismisses or explains away consciousness. We know it can't be that simple.

We spoke to the head of operations at CERN to find out what it takes to fire the collider back up after a brief hiatus for upgrades and maintenance.

The research provides new insight into the maneuvers required to safely and quickly transport heavy loads.

Magnets, or the magnetic fields created by moving electric charges, can attract or repel other magnets, and change the motion of other charged particles.

This 'deceptively simple' question demands a dip into the murky waters of quantum physics.

The mega-experiment deep underground will attempt to discover why matter overwhelmed antimatter in the early universe.

One of the top posts on r/Showerthoughts is It's off-putting that ()() isn't a palindrome, yet ())( is. I agree. The absolute value operator |x| is first taught as "if x is negati…

[This is a transcript of the video embedded below. Some of the explanations may not make sense without the animations in the video.] Like most videos on YouTube, this is a video about nothing. But we're a science channel, so we'll talk about nine levels of nothing. What are the nine levels of nothing? Can you really make a universe from them? And if someone asks you why there is something rather than nothing,…

Here I will show a

It takes years of on-the-job training to learn the ins and outs of particle accelerator operation.

In 1975, three CERN theorists, John Ellis, Mary K. Gaillard and Dimitri Nanopoulos, undertook the first comprehensive study of the collider phenomenology of the Higgs boson. Almost 40 years later, it was discovered at the LHC. Now, ten years on, might we have such long-term foresight in anticipating the varied paths that future Higgs research may follow?

Making Bohmian mechanics fully compatible with special relativity is still an ongoing challenge. Here, the authors make a further step in this direction by providing a way of constructing the relativistic Bohmian-type velocity field of single photons which is operationally based on weak measurements.

Virtual Lab by Quantum Flytrap explores novel ways to represent quantum phenomena in an interactive and intuitive way. It is a no-code online laboratory with a real-time simulation of an optical table, supporting up to three entangled photons. Users can place typical optical elements (such as beam splitters, polarizers, Faraday rotators, and detectors) with a drag-and-drop graphical interface. Virtual Lab operates…

A study led by Dr. Guancong Ma (Department of Physics, Hong Kong Baptist University, Kowloon Tong, Hong Kong, China) and Dr. Kun Ding (Department of Physics, Fudan University, Shanghai 200438, China) provides a new perspective for the study of non-Abelian phenomena and states permutations.

The field of experimental quantum communication promises ways of efficient and unconditional secure information exchange in quantum states. The possibility of transferring quantum information forms a cornerstone of the emerging field of quantum communication and quantum computation. Recent breakthroughs in quantum computation with superconducting circuits trigger a demand for quantum communication channels between…
