	Quantum entanglement - Wikipedia, the free encyclopedia
		Observations on entangled states naively appear to conflict with the property of Einsteinian relativity that information cannot be transferred faster than the speed of light.
		Although two entangled systems appear to interact across large spatial separations, no useful information can be transmitted in this way, so causality cannot be violated through entanglement.
		This demonstrates that, as expected, the reduced density matrix for an entangled pure ensemble is a mixed ensemble.

	NASA - SpaceResearch - Spooky Atomic Clocks
		Entangled clocks could be as much as 1000 times more stable than their non-entangled counterparts.
		Suppose you measure one of the entangled particles and, by doing so, you nudge it "up." This causes the entangled partner to spin "down." Making the measurement "here" affected the other particle "over there" instantaneously, even if the other particle was a million miles away.
		In an entangled atomic clock, however, the improvement is directly proportional to the number of atoms.

	Entangled Particle Holographic Optical Nanostorage
		The first devices using entangled quantum atomic/photon/molecular switches will use optical fiber cable to make optical connections with the hope of eventually going to the ultimate theoretical application of a wireless or cable less quantum computing device as illustrated by the animated gif.
		This is an extension of the known process of quantum emission/absorption and analogous to non-local quantum entanglement of the ferroelectric particle pairs matter.
		Entangled Particle Holographics extends the reach of quantum physics beyond the atom and subatomic particles, not only deeper into the optical media data quantum substrate, but also into the larger world of encrypted data transmission.

	Physics News Update 754
		Take the case of two photons entangled with respect to polarization, the orientation of the electric field associated with the photon.
		In the Illinois experiment, two photons, produced in a "down-conversion" process whereby one photon enters an optical crystal and sunders into two lesser-energy correlated daughter photons, are entangled not just in terms of polarization, but also in a number of other ways: energy, momentum, and orbital angular momentum (see PNU 721).
		Kwiat (217-333-9116, kwiat@uiuc.edu) says that his lab detects a record two million entangled photon pairs per second with ample determination of numerous properties, allowing a complete characterization of the entanglement produced.

		Entangled Particle in which the event history of optical entangled molecules is continuously emitted (broadcast) non-locally and is received by and interacts with the other entangled particle pair's matter in its environment through a subtle process of exchange of quantum information.
		Entangled Particle extends the reach of quantum physics beyond the atom and subatomic particles, not only deeper into the data quantum, but also into the larger world of encrypted data transmission.
		Entangled Particles focus not so much on particles as on the relationships and dynamic exchanges between energy, matter, photons, electric fields, and information.

	Quantum trick may multiply CD capacity - 12 May 2004 - New Scientist
		Their method for 'entangling' photons could one day allow information to be more densely crammed and read from CDs and other memory devices.
		Lundeen's team fired a pair of entangled photons and a lone photon from a laser simultaneously at opposite sides of a partially reflecting glass plate.
		For example, says Lundeen, entangling the photons from the red lasers in CD players would instantly increase the amount of data that could be stored on the discs.

		For example, the moment two people decide to attend a meeting, they have become entangled with one another, even though they could be on opposite sides of the globe.
		In the aftermath of quantum theory, English philosopher Alfred North Whitehead declared that physics had to be entirely rewritten in terms of a general theory of the organism.
		Given this background, I propose that the organism is, in the ideal, a quantum superposition of coherent activities, with instantaneous, non-local intercommunication throughout the system.

	Quantum Entanglement and Information
		This is an entangled state and not the output that would be required by a successful copying operation, where the control and target each outputs the superposed qubit (which could be written as (0+1)(0+1)).
		The two entangled states in the ‘constant’ case are orthogonal in the 4-dimensional two-qubit state space and span a plane.
		The idea, roughly, is that an entangled state of the sort that arises in the quantum computation of a function, which represents a linear superposition over all possible arguments and corresponding values of the function, should be understood as a manifestation of parallel computations in different worlds.

	Dean Radin - Entangled Minds
		They accepted that the microscopic world of elementary particles could become curiously entangled, but those entangled states were assumed to be fleeting and have no practical consequences for the world as we experience it.
		There are theoretical descriptions showing how tasks can be accomplished by entangled groups without the members of the group communicating with each other in any conventional way.
		As we explore the concept of psi as "entangled minds," we'll consider examples of psi experiences in life and lab, we'll review the origins of psi research, we'll explore the results of thousands of controlled laboratory tests, and we'll debunk skeptical myths about psi.

	Light and atoms get entangled (January 2006) - News - PhysicsWeb
		For example, two particles can be entangled such that the polarization of one particle is always "horizontal" when the spin of the other is "vertical", and vice versa; or that the spin of one particle is "up" when the other is "down", and vice versa.
		Although physicists can now routinely entangle photons and send them over long distances down optical fibres, these particles are difficult to store for long periods and so are not ideal as qubits for real quantum information systems.
		The physicists began by preparing an entangled state of one of these atomic qubits and a single photon in a magneto-optical trap in their laboratory.

	Laser Focus World - Entangled photons beat the diffraction limit
		A scheme to use entangled photons is being investigated to achieve the simultaneous arrival of two photons, which increases the two-photon-fluorescence excitation yield.
		Entangled photons exist in a common quantum state.
		But entangled photons have a second property apart from simultaneous generation that renders them highly interesting for resolution improvement in interferometry, metrology, and imaging.

	Entangled Atomic Beams
		According to quantum mechanics, a pair of specially prepared particles can be far apart but retain a bizarre "entangled" relationship, where measurement of one has an immediate impact on the state of the other.
		These entangled beams would allow new tests of the weirdest ideas in quantum mechanics and new avenues of research into the fundamental concepts of quantum information, the basis for quantum computing and quantum cryptography.
		If entangled photon pairs are produced at a high enough rate, the individual particles merge into continuous light beams which have been used to test the so-called Bell inequalities, the fundamental equations describing entanglement.

	Entangled Edens
		Entangled Edens persuasively argues that the Amazon can only be grasped, understood, and come to terms with through its myths and stories.
		Throughout Entangled Edens, the voices of contemporary Amazonians mingle with the analyses of such writers as Claude Lévi-Strauss, Theodore Roosevelt, and nineteenth-century naturalist Henry Walter Bates.
		Slater convinces us that these stories and ideas, together with an understanding of their origins and ongoing impact, are as critical as scientific analyses in the fight to preserve the rain forest.

		ENTANGLED is an entertaining erotic romance with a touch of the paranormal and a reasonable amount of suspense needed to justify the couple pairing off yet also enhances the relationship between the CEO and the security guru.
		The story line is filled with sexual encounters between the lead couple that touch on her submissive nature (being a tough powerful CEO must be caused by reaction formation) with him proving the right amount of domination to satisfy her.
		ENTANGLED is a very welcome addition to the paranormal books out there and should appeal to a variety of readers.

	entanglement - a definition from Whatis.com
		Particles, such as photons, electrons, or qubits that have interacted with each other retain a type of connection and can be entangled with each other in pairs, in the process known as correlation.
		Knowing the spin state of one entangled particle - whether the direction of the spin is up or down - allows one to know that the spin of its mate is in the opposite direction.
		Even more amazing is the knowledge that, due to the phenomenon of superposition, the measured particle has no single spin direction before being measured, but is simultaneously in both a spin-up and spin-down state.

	Noisy Pictures Tell a Story of 'Entangled' Atoms, JILA Physicists Find
		The method demonstrated at JILA also could enable scientists to “see,” for the first time, other types of correlations between atoms in fermionic condensates, a new quantum state first created by the same JILA research group (see http://www.nist.gov/public_affairs/releases/fermi_condensate.htm), in which thousands of pairs of atoms behave in unison.
		This noise is not random, as would be expected ordinarily, but rather appears in duplicate patterns suggesting, although not proving, that pairs of atoms are entangled with each other—even when separated by as much as 350 micrometers.
		The pairs of entangled atoms can then be found by carefully studying the noise pattern in these pictures.

	Method found to 'purify' partially entangled states
		"Entangled states tend not to remain pure, due to interactions with the environment," said Kwiat, a John Bardeen Professor of Electrical and Computer Engineering and Physics at the UI.
		In quantum mechanics, the properties of entangled photons, for example, are inextricably linked to each other -- even if the photons are located on opposite sides of the galaxy.
		When applied to partially mixed states, the distillation procedure generated states that subsequently demonstrated nonlocal correlations, even though the initial states did not, the researchers reported.

		Entangled particles are the bread-and-butter of quantum information schemes such as quantum cryptography, quantum computing, and quantum teleportation.
		Since the entangled pair and reflected laser pulse behave as waves, quantum mechanics says that they could interfere constructively to generate fourfold more two-photon pairs or interfere destructively to create zero pairs.

	Bright and pure source of highfidelity entangled photons for quantum computation and teleportation
		For example, the properties of entangled photons are inextricably linked to each other, even if the photons are located on opposite sides of the galaxy.
		A major production problem, however, is that entangled photons are emitted in many directions and with a wide range of polarization phase relationships, each acting like an individual singer in a large choir.
		Ultrabright, ultrapure sources of entangled photons are essential for pursuing quantum computing and quantum networks, as a resource for teleportation in quantum communication, and for sending more information faster by means of quantum cryptography.

		Modern clocks have improved to such a level that the resolution and accuracy of the comparison techniques have become the limiting factors to determine the degree of synchronization, t1-t2.
		New ideas, exploiting the novel aspects of entangled photons, say that quantum mechanics can overcome the classical limit in regard to clock synchronization (see Update 499).
		Pairs of entangled photons are produced in a nonlinear crystal and will retain a special quantum correlation between themselves (belonging, as they do, to a single quantum state) even if they were to move apart to distances of trillions of km.
