Scientists Finally Measure the Lightning-Fast Speed of Quantum Entanglement: Revolutionary Breakthrough in Quantum Physics
Understanding Quantum Entanglement Speed: The Most Significant Discovery in Modern Physics
For decades, scientists studying quantum mechanics have wondered about one fundamental question: how fast does quantum entanglement actually occur? This mystery surrounding the speed of quantum entanglement has finally been solved by researchers at TU Wien, marking a revolutionary breakthrough in quantum physics research that could transform our understanding of subatomic particle behavior.
The implications of measuring quantum entanglement speed extend far beyond theoretical physics. As we advance toward practical quantum computing applications, understanding these quantum mechanical processes becomes increasingly vital for developing next-generation quantum technologies.

What Makes Quantum Entanglement So Extraordinary?
Quantum entanglement represents one of the most fascinating phenomena in quantum physics. When particles become quantum entangled, they develop an instantaneous connection that defies our everyday understanding of physics. This quantum mechanical phenomenon allows entangled particles to influence each other's properties regardless of the distance separating them.
The Bizarre World of Quantum Mechanics Explained
The quantum world operates according to rules that seem impossible in our macroscopic reality. At the subatomic level, particles can exist in multiple states simultaneously through quantum superposition, similar to the famous Schrödinger's cat thought experiment. These quantum mechanical properties challenge our classical understanding of reality.
Quantum entanglement occurs when two or more subatomic particles share quantum states in such a way that measuring one particle instantly affects the quantum state of its entangled partner. This phenomenon has puzzled physicists since Einstein famously called it "spooky action at a distance."
Breakthrough Research: Measuring Quantum Entanglement Formation Time
The research team at TU Wien conducted groundbreaking experiments to determine exactly how long quantum entanglement formation takes. Their findings revealed that quantum entanglement doesn't happen instantaneously as previously thought, but occurs at incredibly fast speeds measured in attoseconds.
Understanding Attosecond Timescales in Quantum Physics
An attosecond represents one-quintillionth of a second (1/1,000,000,000,000,000,000), making it virtually incomprehensible in human terms. To put this quantum entanglement timescale in perspective, there are more attoseconds in one second than there have been seconds since the universe began.
Professor Joachim Burgdörfer from the Institute of Theoretical Physics at TU Wien explained that entangled particles lose their individual properties, sharing only common quantum characteristics. "From a mathematical point of view, they belong firmly together, even if they are in two completely different places," Burgdörfer noted.

Revolutionary Experimental Methods for Creating Quantum Entangled States
The researchers developed innovative techniques to create quantum entangled particles and measure their formation time. Their experimental approach involved using high-intensity, high-frequency laser pulses to blast atoms and create entangled electron pairs.
The Laser-Induced Quantum Entanglement Process
The quantum entanglement creation process begins when researchers direct intense laser pulses at target atoms. This high-energy interaction causes one electron to be expelled from the atom entirely, while simultaneously affecting a second electron within the same atom. The second electron enters a higher energy state and shifts its orbital position while remaining bound to the atomic nucleus.
This carefully controlled process creates quantum entangled electron pairs that maintain their mysterious connection even after separation. The researchers confirmed the quantum entanglement by demonstrating that measurements performed on one electron immediately influence the quantum state of its entangled partner.
Measuring Quantum Entanglement Birth Time
Using sophisticated dual-laser beam techniques, the physicists measured what they term the "birth time" of quantum entanglement formation. Their experiments revealed fascinating correlations between the timing of quantum entanglement creation and the energy states of the particles involved.
When the remaining atom exists in a higher energy state, the departed electron likely left at an earlier point in the quantum entanglement formation process. Conversely, when the atom remains in a lower energy state, the quantum entanglement formation occurred later, taking an average of 232 attoseconds to complete.
The Wave Nature of Quantum Entanglement Formation
Assistant Professor Iva Březinová from TU Wien's Institute of Theoretical Physics provided crucial insights into the quantum mechanical nature of entanglement formation. She explained that electrons don't simply "jump out" of atoms during the quantum entanglement creation process.
"The electron is a wave that spills out of the atom, so to speak – and that takes a certain amount of time," Březinová explained. "It is precisely during this phase that the entanglement occurs, the effect of which can then be precisely measured later by observing the two electrons."
This wave-like behavior during quantum entanglement formation represents a fundamental aspect of quantum mechanics, where particles exhibit both wave and particle characteristics depending on the experimental conditions.
