Recent theoretical and experimental breakthroughs have given rise to the emerging field of free-electron quantum optics, reshaping the understanding of free-electron physics. Traditionally rooted in ...

A new study explores the behavior of photons, the elementary particles of light, as they encounter boundaries where material properties change rapidly over time. This research uncovers remarkable ...

Over the past decade, quantum computing has grown into a billion-dollar industry. Everyone seems to be investing in it, from tech giants, such as IBM and Google, to the US military. But Ignacio Cirac ...

A routine quantum optics technique just revealed an extraordinary secret: entangled light can carry incredibly complex topological structures. Researchers found these hidden patterns reach up to 48 ...

Degenerate quantum gases arise when ultracold atomic vapours occupy quantum states whose thermal de Broglie wavelength exceeds the mean interparticle spacing. In Bose–Einstein condensates (BECs) ...
