EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the material. "The concept of time has troubled philosophers and physicists for ...

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing that idea is challenging.

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

The study shows that in quantum devices, reading a clock consumes far more energy than running it. This insight will help ...

MIT physicists and colleagues have for the first time measured the geometry, or shape, of electrons in solids at the quantum level. Scientists have long known how to measure the energies and ...

Physicists have struggled to understand the nature of time since the field began. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Time may not be ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

(Nanowerk News) Although systems consisting of many interacting small particles can be highly complex and chaotic, some can nonetheless be described using simple theories. Does this also pertain to ...

Sorta sparked by this comment someone made to me but it's similar to what other people have told me before: I was listening to a lecture on quantum electrodynamics and it helped me conceptualize the ...
