The birds do not demonstrate the "spooky physics" of entangled quantum particles.
According to quantum theory, all particles are wave-like (and all waves particle-like).
The behavior could let communications and storage take advantage of quantum entanglement, where particles can affect each other despite relatively long distances.
ENGADGET: MIT demos new form of magnetism that could lead to quantum communication, storage
Scientists can make quantum computers from light particles known as photons, but they can also use an array of single atoms or even very small electrical circuits.
FORBES: Teeny-Tiny Quantum Computers Take A Step Closer To Reality
This (put your analyst on danger money) means magnetised graphene is inhabited by quasiparticles, which have the quantum properties of real particles (electrons, protons and so on) without actually being particles.
It was part of a thought experiment intended to illustrate the bizarre nature of the quantum world, in which particles can persist in two states at once and, as a consequence, a cat can be both dead and alive.
"Quantum entanglement is valuable in transmitting particles such as atoms and photons where the most delicate properties are significant and where simple approximation is not enough, " he explains.
The Sommerfeld effect, a quantum-mechanical process that makes particles more likely to interact with one another in some circumstances and less likely in others, is mostly ignored in particle physics because it applies only in a limited range of conditions.
ECONOMIST: Two new ways to detect the elusive stuff of the universe
The "quantum states" of atoms, light particles known as photons, molecules and even objects big enough to be seen have been extensively studied.
When you consider quantum physics you recognize the fact that all particles (even the subatomic ones) have a split-personality, of sorts.
However, quantum manipulations involving any more than a tiny number of particles together quickly become too hard to do.
But transmitting single particles or, to be accurate, copying the quantum state of one particle on to another, perhaps of a different kind could one day have less science-fictional uses.
This is that the universe popped out of nowhere about 13.7 billion years ago in a quantum fluctuation similar to the sort that constantly create short-lived virtual particles in so-called empty space.
Quantum mechanics tells us that if such a Higgs field exists, then one can produce real particles out of the field if one throws enough energy into a small enough volume.
That does not affect their electrical conductivity, but nanoscale particles like this are known to scatter and obstruct the passage of heat through imperfectly understood quantum-mechanical processes.
Quantum key distribution does this by encoding the information in the polarisation states of individual photons, the particles of light, which are sent from Alice to Bob over an optical fibre.
ECONOMIST: Secure cryptography is only as safe as its weakest link
In the quantum world, things traditionally thought of as waves, such as light, can also be viewed as particles.
