Quantum Information
-
Standard quantum encoding attributes just one quantum bit of information to each of an entangled photon pair. Now researchers have increased that data-carrying capacity more than 30 times by using a technique known as hyperentanglement
-
Using atoms of the rare-earth element europium, scientists from the Australian National University have shattered previous records for quantum information retention by creating a storage device capable of holding quantum state information for up to six hours at a time.
-
ScienceQuantum technologies are becoming increasingly difficult to advance without memories able to appropriately store atomic-spin information. To help address this problem, scientists from the University of Warsaw claim to have developed a laser-driven atomic memory.
-
Researchers at the University of New South Wales have each achieved records in processing quantum data with an accuracy above 99 percent and the storage of coherent quantum information for more than thirty seconds, both of which are essential for creating future super-fast quantum computers.
-
SciencePhysicists at the University of Geneva claim to have succeeded in passing information from light into matter using the teleportation of a photon via optical fiber cable to a receiving crystal located over 25 km (15 m) away
-
ScienceUsing high-powered laser interferometers to determine if space-time is a quantum system made up of countless tiny bits of information, Fermilab scientists are conducting an experiment to see if the universe is "real" or a holographic 3-D illusion.
-
ScienceResearchers in the Netherlands claim to have successfully transferred data via teleportation across the width of a room, and hope to go on to prove that Einstein's rejection of the theory of entanglement was wrong.

SciencePhysicists have developed a method to make quantum teleportation much more efficient than was previously possible, leading the way to better quantum computers and, perhaps, the teleportation of object and humans.
