Cross-Dimensoinal Quantum Entanglement and Last Night's Storms

Another thing pointed out by wacko1138, this morning: Physicists Demonstrate Qubit-Qutrit Entanglement

'For the first time, physicists have entangled a qubit with a “qutrit” – the 3D version of the 2D qubit. Qubit-qutrit entanglement could lead to advantages in quantum computing, such as increased security and more efficient quantum gates, as well as enable novel tests of quantum mechanics.

'The research team, composed of physicists from the University of Queensland, the University of Bristol, and the University of Waterloo, has published its results in a recent issue of Physical Review Letters. The researchers made qutrits with biphotons (two correlated photons), resulting in “biphotonic qutrits.” Then, they entangled these qutrits with photonic qubits (made with one photon) using a combination of linear optic elements and measurements....

'“For me, the significance our paper is about how entangling systems to a qubit can be a great way to manipulate that system,” co-author Benjamin Lanyon of the University of Queensland told PhysOrg.com. “In our example, we use this technique to dramatically extend the range of possible transforms on qutrits – these higher dimensional quantum information carriers, which offer loads of advantages, but are otherwise really difficult to handle.” '

I would like to stress, again, that this is the further manipulation of a thing that changes due to measurement and observation. Just something to think about.

There was a major thunderstorm, last night. Such a storm that I'm actually surprised that there aren't any downed trees or powerlines. I'd been reading The Monarch of the Glen, before bed, and there was quite a bit of caffeine consumption... Choppy dreams. Crashing sweeping dreams. Dreams of tables in the middle of courtyards that used to be stone and were then grass, the steps like a royal court and Shakespearean ruins. Dreams of snide and snippy comments directed at those not seated at the table, and my leaning on the good points of any maligned person, to the maligner.

Dreams of unrequited love, of a weirdly divided house, and Heather Graham (again), and a character like Brian, from Family Guy. He loved her, but couldn't express it properly, and would instead pretend to be asleep in the room between the shower and her room; the common area which was somehow his room. She would walk through in a towel, and he would pretend to be asleep on his bed, and watch her, because he couldn't bring himself to tell her the truth...

Sad.

Jonathan Z. Smith (1987): 'The nostalgic literature of home is filled with these sorts of reveries: moments of significance, private or shared, imcomprehensible to those outside. Home is perceived as the condensation of such reveries. Home is not, from such a point of view, best understood as the place-where-I-was-born or the place-where-I-live. Home is the place where memmories are "housed." As such, home is unique: "There's no place like home."'

Get it?

Good morning.

Blargh.

Dreams were epic and unremembered. Lost in the again-decision to slide life together. Luckily, successful with that part.

Fun bits with the qubits, not sure whether I'm really grasping it or just reading it.

There is no place like home. I think that's another difficulty.

Good evening.

Gets harder and harder to know for sure...

Good luck.

Oddly, I keep seeing that stone table cracked in half, violently, like a seal.

And I'm wondering how they began entangling different particles. I thought entanglement was a trait of the same particle, existing in two places at once. Having something exist as two different things, in two different places, is the part of that that gives me pause.

All things are the same thing. Or, rather, are made of the same stuff. Anything can be made to be anything else. Principles of alchemy, in our best science, and all that :)
