Hyperentanglement
Thursday, July 2, 2015
UCLA electrical engineers led a team of researchers and demonstrated a new way to harness photons so that no matter how far apart they are they still act in unison. The success of this development is thanks to a method call hyperentanglement. Hyperentanglement occurs when you slice up and entangle each photon pair into multiple dimensions using quantum properties. Learn about Hyperentanglement and how it allows each photon pair to carry more data that previously possible, below.
Quantum entanglement could allow users to send data through a network and know immediately whether that data had made it to its destination without being intercepted or altered. With hyperentanglement, users could send much denser packets of information using the same networks.
The research, published today in Nature Photonics, was led by Zhenda Xie, a research scientist in the lab of Chee Wei Wong, a UCLA associate professor of electrical engineering who was the research project’s principal investigator. Researchers from MIT, Columbia University, the University of Maryland and the National Institute of Standards and Technology were also part of the team.
Albert Einstein famously described quantum entanglement as “spooky action at a distance” because it seems so improbable that what happens to one particle in an entangled pair also happens instantly to the other particle, even over great distances. The phenomenon exceeds the speed of light.
In the new study, researchers sent hyperentangled photons in a shape known as a biphoton frequency comb, essentially breaking up entangled photons into smaller parts.
In secure data transfer, photons sent over fiber optic networks can be encrypted through entanglement. With each dimension of entanglement, the amount of information carried on a photon pair is doubled, so a photon pair entangled by five dimensions can carry 32 times as much data as a pair entangled by only one. The result greatly extends from wavelength multiplexing, the method for carrying many videos over a single optical fiber.
As our ability to send, share and access information becomes more reliable we can better utilize information to discover the mystery of Bigfoot. Ron Morehead has been investigating the Bigfoot phenomena for over 4 decades and has come to believe the answers may lay in the further understanding of Quantum Physics.
