- 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.
- 2Vacuum Entanglement Vanishes in Strong Fields, Study Finds●Researchers Find Vacuum Entanglement Vanishes In Strong Fields
Researchers report that entanglement present in the quantum vacuum disappears when exposed to strong external fields. The finding suggests that powerful fields can strip away the correlated quantum fluctuations normally thought to permeate empty space. If confirmed, the result could refine how physicists model extreme environments such as intense lasers or regions near black holes, and may influence future quantum technology research.
- 3Scientists Watch Particles Pop Into Existence on Quantum Computer▼Scientists Watch New Particles “Pop Into Existence” on a Quantum Computer
Researchers report simulating quantum vacuum conditions on a quantum computer, observing particle pairs appear to pop into existence in real time. The demonstration offers a way to visualize effects that are normally impossible to observe directly, and physicists say such simulations could deepen understanding of quantum field theory and the fundamental nature of empty space.
