The first images of spooky action at a distance.
Imagine reading a library at once rather than one book at a time — that’s what quantum computers can do.
Quantum mechanics — how does it work?!
‘Spooky action at a distance’ is approaching the human scale.
Sharing sensitive data will never be the same.
This is the beginning of the quantum internet.
Now, the cat is both dead and alive and sits in two boxes — all at the same time. Here goes nothing.
A group of scientists working at the National Institute of Standards and Technology (NIST) has managed to successfully transfer information from on proton to another one 100 kilometers away (60 miles). This could ultimately lead not to actual teleportation, but rather to unhackable conversations.
One of the predictions derived from Einsten’s theory of general relativity is the existence of wormholes – spacetime shortcuts. In theory such bridges may offer instantaneous travel between the two bridgeheads or wormholes even if these are light-years away from each other. Two independent studies suggest that there’s a link between quantum entanglement and wormholes, or to be more precise:
One of the most mysterious, and weirdest at the same time, phenomenae in quantum physics is quantum entanglement, in which two connected particles can share information instantly despite being separated, no matter the distance. Two particles, or so the theory holds, could be parted by light years in distance and still reflect each others’ stances instantly, an oddity which prompted Einstein
To be quite honest, there are moments when I feel that I don’t understand quantum mechanics at all – the phenomena involved in the field are so complex and counter intuitive one can only stop and wonder if God does in fact play dice with the Universe… but at any rate, the advancements produced by quantum mechanics are, as Einstein
Is light a wave, or is it made of particles? This question has puzzled since the dawn of modern physics, because somehow, light seemed to behave preferentially, depending on the situation – it was either a wave or a particle, but never both at the same time. This new quantum experiment seems to show that light can be both simultaneously,
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 –
Effective quantum computers are still far away, but researchers are already showing more and more advantages these devices would bring to the table. A trio of theorists have shown one more talent of a quantum computer: it would be powerful enough to study the inner workings of the universe in ways that are far beyond the reach of even the
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 at University of Bristol‘s Centre for Quantum Photonics have remarkably managed to create a multi-purpose optical chip capable of manipulating and measuring quantum entanglement and mixture – two important quantum effects which have been giving researchers headaches for a long time, but which can now be controlled and used to characterize quantum circuits. This is a considerable leap forward
The quantum world is entirely different from what we see around us; it has its own laws, its own algebra, etc. It’s a really bizarre place, but that can yield wonderous developments as well. Since the quantum laws are so different, it’s hard to actually observe them, so instead, thought experiments are used. But for the first time, that has
