Scientists at TU Wien measured the speed of quantum entanglement for the first time, finding it occurs in about 232 attoseconds, challenging the previous belief that it happens instantaneously, which is crucial for advancing quantum computing.
Attosecond-level precision in physics is an incredible achievement, but it is not fast enough to measure all processes in nature. While it can describe gravitational and electromagnetic interactions, it falls short in explaining and probing weak interactions and interactions mediated by the strong nuclear force. To truly understand the universe at its most fundamental levels, scientists will need to achieve yoctosecond (~10^-24 second) precision. This limitation arises from the nature of particles, their lifetimes, and the strong interactions. Attosecond-level precision is sufficient for measuring the positions and properties of atoms and molecules, but for subatomic particles, yoctosecond-level precision is required.
