- 1Quantum computer simulates matter popping into existence▼Quantum computer simulates matter “popping into existence”
Researchers have used a quantum computer to simulate particles of matter appearing out of the vacuum, reproducing a phenomenon predicted by quantum field theory in which energy can briefly convert into matter-antimatter pairs. The experiment offers a new way to study fundamental physics that is otherwise out of reach of traditional computers, and physicists say such simulations could help probe processes occurring in the early universe.
- 2Researchers achieve record precision in early-universe measurement●Researchers pinpoint key early-universe measurement with record precision
Researchers report that they have determined a key measurement relating to the early universe with record-breaking precision. The result is described as the most accurate of its kind, though the specific quantity measured and the team behind it have not been detailed. More precise early-universe measurements help scientists test models of the cosmos's first moments and constrain theories of how the universe evolved.
