Probing conjugation and parity symmetry with entangled double-strange baryons

The Beijing Spectrometer (BESIII) Collaboration has reported a new method for probing differences between matter and antimatter with extreme sensitivity. Results were published in Nature on June 2.

Scientists use quantum processor to simulate 2D states of quantum matter

What would it be like if we lived in a flat two-dimensional world? Physicists predict that quantum mechanics would be even stranger in that case, resulting in exotic particles—so-called "anyons"— that cannot exist in ...

Playing games with quantum interference

As Richard Feynman famously put it, "the double slit experiment is absolutely impossible to explain in any classical way and has in it the heart of quantum mechanics. In reality, it contains the only mystery."

Charting a course toward quantum simulations of nuclear physics

In nuclear physics, like much of science, detailed theories alone aren't always enough to unlock solid predictions. There are often too many pieces, interacting in complex ways, for researchers to follow the logic of a theory ...

Synthetic magnetism leads photons on a 2-D quantum walk

Randomness governs many things, from the growth of cell colonies and the agglomeration of polymers to the shapes of tendrils that form when you pour cream into a cup of coffee.

Uncertainty revisited: Novel tradeoffs in quantum measurement

(Phys.org) —There is, so to speak, uncertainty about uncertainty – that is, over the interpretation of how Heisenberg's uncertainty principle describes the extent of disturbance to one observable when measuring another. ...

Speed limits for quantum phenomena have been extended to macro-sized objects

An expression for the maximum speed at which changes in macroscopic systems can occur has been derived by a theoretical physicist at RIKEN. This will deepen our understanding of quantum phenomena in systems that are not in ...

Team finds an easier optimal detection scheme for near-term quantum sensors

Quantum holds the promise of increasing the power of sensing technologies. While the field of quantum sensing has shown a lot of potential for detecting very small signals, the ability to truly optimize these sensors has ...

In a new quantum simulator, light behaves like a magnet

Physicists at EPFL propose a new "quantum simulator": a laser-based device that can be used to study a wide range of quantum systems. Studying it, the researchers have found that photons can behave like magnetic dipoles at ...
