One of the fundamental challenges of quantum computing is obtaining information from a quantum bit, or qubit. Unlike a conventional bit, which can be read repeatedly without altering its content, direct measurement of a quantum system typically causes the state to collapse before it can be determined. In other words, reading the information modifies it.

Three giant black holes discovered in a galaxy from the dawn of time

Astronomers have discovered three actively feeding black holes inside a single galaxy more than 12.5 billion light-years away, revealing a remarkable scene from the universe’s infancy. Two of the black holes are separated by just 620 light-years and are expected to eventually mer

'One-positron cyclotron' could test a key prediction of the Standard Model

The positron is the antimatter counterpart of the electron, identical in mass but carrying an equal and opposite electric charge. Like the electron, it also behaves like a tiny bar magnet, and according to a key prediction of the Standard Model of particle physics, its magnetic m
