The device is completely self-contained, being able to determine the position of an object on the globe with no external reference required.
Physicists may have solved ‘chicken or the egg’ paradox — both can come first
Of course it had to be weird and confusing.
Scientists demonstrate quantum entanglement with objects big enough to see
‘Spooky action at a distance’ is approaching the human scale.
Quantum technology of spinning black holes
Are black holes trying to tell us something?
Musk’s argument that we live in a simulation doesn’t hold water, quantum physicists say
The blue pill or the red pill?
China launches first quantum satellite making its communications unhackable
Teleporting quantum states might the future of communications, and China is leading the way.
Water squeezed in a new state: not liquid, nor solid or gas. Just pure quantum weirdness
Physicists have crammed water inside extremely small cracks about ten-billionth of a metre and found the molecules entered a never before seen state. In this brand new state, the water molecules don’t adhere to strict laws of classical physics anymore, nor do they behave like a liquid, gas or solid.
Gamers help solve quantum physics problem where A.I. failed
After an A.I. beat the human champion at Go, a game almost infinitely more complex than chess, some might feel like tossing the towel and let our robot overlords take their rightful place. Not so fast! We’re still good for something. Pressed to find a solution for a complicated quantum physics problem that neither the researchers themselves nor an algorithm could properly solve, Danish physicists turned to the gaming community. They devised a game which mimicked the task at hand while also keeping it fun, and found some gamers came up with novel “outside the box” solutions which the algorithm couldn’t even touch. Points for humanity!
Book review: ‘The Quantum Moment’
How the quantum moment “overturned basic beliefs about space and time, causality and reality, and exposed as mistaken many fundamental cultural and philosophical assumptions.”
Quantum physics used to make virtually uncrackable authentication system
Security experts have devised a novel authentication system that exploits quantum effects to make fraud-proof credit cards or IDs. Called Quantum-Secure Authentication (QSA), the technology relies on the quantum properties of single light beams, called photons, including their ability to be in multiple places at once. Quantum physics keys “We experimentally demonstrate quantum-secure authentication (QSA) of a classical multiple-scattering key. The
Measuring particle momentum without breaking the uncertainty principle
Heisenberg’s uncertainty principle makes quantum physics nasty. There’s no reason why we can’t get all along, though. A novel technique explores how it may be possible to know both position and momentum for a particle. No laws of physics were broken. I promise!
Quantum theory takes out singularity, suggests black holes are wormholes
Black holes are the single most interesting and puzzling objects in our Universe – that we know of. But as if they weren’t mysterious enough, researchers have found that if you apply a quantum theory of gravity to these bizarre objects, the all-crushing singularity at their core disappears, opening a whole new Universe of possibilities – literally. What we know
Scientists image an atom’s shadow for the first time
For the first time ever the shadow of an atom (yes, even an atom can cast a shadow) has been imaged using a complex technique which involved a laser beam and a a Fresnel lens. The culmination of their five-year work is this fantastic snapshot from above, and although this dark spot is quite tiny, the implications of the research in
Physicists quantum teleport photons over 143 kilometers
Last May, European scientists managed to teleport photons using quantum phenomena over a distance of 143 kilometers, across two Canary islands; however, it is only now that their paper was accepted in a peer reviewed magazine. Beam me up, Scotty While the technology used in Star Trek is still only science-fiction, the quantum teleportation of photons is a reality –
Scientists devise qubits in a semiconductor for the first time
Hailed as yet another big step towards devising working quantum computers, scientists at Ruhr-Universität Bochum (RUB) have successfully managed to generate quantum qubits inside a semiconductor for the first time, instead of vacuum. A qubit is the quantum analog of a bit. While a bit must be read either as a 0 or 1, the qubit can be read as 0, as
Scientists cool semiconductor with laser light
By harnessing the science of both quantum and nano physics, scientists at the Niels Bohr Institute have come up with an innovative new way of cooling semiconductor membranes by using laser light. Through this new technique, the researchers were able to cool the tiny, thin membrane from room temperature to -269 degrees Celsius. Paradoxically, the laser warms the bulk semiconductor
Solar paint promises to turn any surface into a solar cell
Researchers have successfully managed to create a “solar paint” made out of quantum dots, which exhibits similar properties to multifilm solar cell architectures. The later are sophisticated, expensive and require a lot of time to deploy; the paint can be easily applied to basically any surface, like a house’s roof, and prepare it to easily generate photocurrent. Quantum dots, simply
The age of nano-electronics: scientists develop one of the world’s smallest circuits
A team of researchers from led by Guillaume Gervais from McGill’s Physics Department and Mike Lilly from Sandia National Laboratories, have managed to develop one of the smallest electronic circuits in the world using nanowires spaced across each other by a distance so small, it has to be measured at an atomic level. Miniaturization has been the dominant trend in the
Truly random numbers might be generated with quantum physics
Does flicking a dice really render a random face? The answer would be no. The dice is governed by large-scale conventional physics and its motion, and thus final position can be determined. You can’t tell where it lands just by looking at it thwirl, of course, but the fact remains it’s not random, and neither is any current computing system
Watch Quantum Levitation in action [AMAZING!]
What you just saw in the video above is a perfect demonstration of the quantum levitation effect, through a fairly simple set-up made by Tel Aviv University scientists, comprised of a track and a semiconductor. The quantum levitation is actually a perfect demonstration of the Meissner effect, which describes the expulsion of a magnetic field from a superconductor during its
