Researchers Teleport Information Between Two Computer Chips for the First Time

Posted by in categories: computing, internet, nanotechnology, particle physics, quantum physics

For the first time, researchers and scientists from the University of Bristol, in collaboration with the Technical University of Denmark (DTU), have achieved quantum teleportation between two computer chips. The team successfully developed chip-scale devices that are able to harness the applications of quantum physics by generating and manipulating single particles of light within programmable nano-scale circuits.

Unlike regular or science fiction teleportation which transfer particles from one place to another, with quantum teleportation, nothing physical is being transported. Rather, the information necessary to prepare a target system in the same quantum state as the source system is transmitted from one location to another, with the help of classical communication and previously shared quantum entanglement between the sending and receiving location.

In a feat that opens the door for quantum computers and quantum internet, the team managed to send information from one chip to another instantly without them being physically or electronically connected. Their work, published in the journal Nature Physics, contains a range of other quantum demonstrations. This chip-to-chip quantum teleportation was made possible by a phenomenon called quantum entanglement. The entanglement happens between two photons (two light particles) with the interaction taking place for a brief moment and the two photons sharing physical states. Quantum entanglement phenomenon is so strange that physicist Albert Einstein famously described it as ‘spooky action at a distance’.

Information teleported between two computer chips for the first time

Posted by in categories: computing, internet, particle physics, quantum physics

Scientists at the University of Bristol and the Technical University of Denmark have achieved quantum teleportation between two computer chips for the first time. The team managed to send information from one chip to another instantly without them being physically or electronically connected, in a feat that opens the door for quantum computers and quantum internet.

This kind of teleportation is made possible by a phenomenon called quantum entanglement, where two particles become so entwined with each other that they can “communicate” over long distances. Changing the properties of one particle will cause the other to instantly change too, no matter how much space separates the two of them. In essence, information is being teleported between them.

Hypothetically, there’s no limit to the distance over which quantum teleportation can operate – and that raises some strange implications that puzzled even Einstein himself. Our current understanding of physics says that nothing can travel faster than the speed of light, and yet, with quantum teleportation, information appears to break that speed limit. Einstein dubbed it “spooky action at a distance.”

Viewpoint: Shooting Ahead with Wakefield Acceleration

Posted by in category: particle physics

A method for accelerating particles, called wakefield acceleration, has notched up its output energy, bringing it closer to its goal of shrinking the size of accelerator facilities.

The field of plasma wakefield acceleration is picking up speed. This method, which was first proposed in 1979 [1], creates a collective motion of plasma particles, generating an accelerating field in its wake. The amplitude of this accelerating field is not limited, as it is in conventional acceleration techniques that use radio frequency pulses. The implication is that wakefield acceleration has the potential to work over much smaller lengths, which would allow a reduction in the size (and cost) of accelerator facilities. There exist different methods for generating wakefields, and now researchers are reporting significant progress for two of these techniques. One method using laser-driven wakefields has generated 8-GeV electrons, a new energy record that doubles the previous record [2].

Laser R&D focuses on next-gen particle collider

Posted by in categories: materials, particle physics

Circa 2016

A set of new laser systems and proposed upgrades at the Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) will propel long-term plans for a more compact and affordable ultrahigh-energy particle collider.

Progress on these laser systems and laser-driven accelerators could also provide many spinoffs, such as a new tool to hunt for radioactive materials, and a miniaturized and highly tunable free-electron laser system enabling a range of science experiments.

First chip-to-chip quantum teleportation harnessing silicon photonic chip fabrication

Posted by in categories: internet, particle physics, quantum physics, supercomputing

The development of technologies which can process information based on the laws of quantum physics are predicted to have profound impacts on modern society.

For example, quantum computers may hold the key to solving problems that are too complex for today’s most powerful supercomputers, and a quantum internet could ultimately protect the worlds information from malicious attacks.

However, these technologies all rely on “,” which is typically encoded in single quantum particles that are extremely difficult to control and measure.

Mars Has Auroras of Its Own Which Could Explain Why the Planet Lost Its Water

Posted by in categories: particle physics, space

Here on Earth, you can see the aurora of the Northern Lights, when solar winds interact with the planet’s magnetosphere. It turns out that Mars has its own auroras too, called proton auroras, but they give off ultraviolet light which makes them invisible to the naked eye.

NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) spacecraft, however, currently in orbit around Mars, is able to detect these auroras using its Imaging UltraViolet Spectrograph (IUVS) instrument. Using data from this instrument, scientists have been investigating the relationship between the proton auroras and the fact that Mars lost its water over time. The Martian aurora is indirectly created by hydrogen in the atmosphere, which comes from water being lost into space.

The animation below shows how the proton aurora is formed. First, solar winds send protons toward Mars, where they interact with a cloud of hydrogen surrounding the planet. The protons take electrons from the hydrogen atoms to become neutrons. These neutral particles can then pass through a region of the planet’s magnetosphere called the bow shock. When the hydrogen atoms enter the atmosphere and collide with gas particles, they give off the ultraviolet light that we call an aurora.
