quantum Entanglement Not Instantaneous, Scientists Discover
vienna – In a revolutionary progress that challenges long-held beliefs, scientists at TU Wein University have successfully measured the speed of quantum entanglement. The findings indicate that this peculiar phenomenon, once believed to be instantaneous, actually occurs at a finite, albeit dazzlingly fast, speed.
Shattering Assumptions About Quantum entanglement
Quantum physics delves into the strange realm of atoms and subatomic particles, where conventional rules often don’t apply. One of the moast intriguing aspects of this field is quantum entanglement, where two or more particles become interconnected in such a way that they share the same fate, regardless of the distance separating them.This connection allows them to influence each other.
“You Could Say That the Particles Have No Individual Properties, They Only Have Common Properties,” Explained Professor Joachim Burgdörfer. “From A Mathematical Point Of View, They Belong Firmly Together, Even If They Are in Two Completely Different Places.”
For years, the prevailing assumption was that this entanglement happened instantaneously. Though, the recent experiments at TU Wein demonstrate that while incredibly rapid, quantum entanglement is not immediate.
The Attosecond Revolution: Measuring the Speed of Quantum Entanglement
The team, led by Professor Burgdörfer, discovered that the entanglement process unfolds on the scale of attoseconds – a unit of time equal to one quintillionth of a second (10^-18 seconds). This mind-boggling speed makes direct measurement exceptionally challenging.
To achieve this feat, researchers employed high-intensity, high-frequency laser pulses to blast atoms. This process caused one electron to be ejected from the atom, sometimes influencing a second electron to jump to a higher energy level while remaining bound to the atom’s nucleus.
“We Can Show That These Two Electrons Are Now Quantum Entangled,” Professor Burgdörfer stated. “You Can Only Analyze Them Together – And You Can Perform A Measurement on One Of The Electrons And Learn Something About The Other Electron simultaneously occurring.”
Through meticulous analysis using two laser beams, the team correlated the “birth time” of the ejected electron with the energy state of the electron remaining in the atom. They found that a higher energy state in the remaining atom correlated with the departing electron leaving earlier, while a lower energy state meant the electron left later. In the latter case, the average time was 232 attoseconds.
According To Iva Březinová, An Assistant Professor At The Institute Of Theoretical Physics At TU Wein, “The Electron Doesn’t Just Jump Out Of The Atom. it Is A Wave That Spills Out Of The Atom,So To Speak – and That Takes A Certain Amount Of Time. It Is Precisely During This Phase That The Entanglement Occurs.”
