Schrödinger's cat caught on quantum film using quantum entanglement

Schrödinger's cat caught on quantum film using quantum entanglement | Stone Soup | Scoop.it

The patron animal of quantum theory poses for a unique portrait in which the camera and the sitter don't share a single photon – except by entanglement.

 

Information is central to quantum mechanics. In particular, quantum interference occurs only if there exists no information to distinguish between the superposed states. The mere possibility of obtaining information that could distinguish between overlapping states inhibits quantum interference1, 2. Gabriela Barreto Lemos at the Austrian Academy of Sciences introduces and experimentally demonstrates a quantum imaging concept based on induced coherence without induced emission3, 4. The experiment uses two separate down-conversion nonlinear crystals (numbered NL1 and NL2), each illuminated by the same pump laser, creating one pair of photons (denoted idler and signal). If the photon pair is created in NL1, one photon (the idler) passes through the object to be imaged and is overlapped with the idler amplitude created in NL2, its source thus being undefined.

 

Interference of the signal amplitudes coming from the two crystals then reveals the image of the object. The photons that pass through the imaged object (idler photons from NL1) are never detected, while we obtain images exclusively with the signal photons (from NL1 and NL2), which do not interact with the object.

 

The experiment is fundamentally different from previous quantum imaging techniques, such as interaction-free imaging5 or ghost imaging6, 7, 8, 9, because now the photons used to illuminate the object do not have to be detected at all and no coincidence detection is necessary. This enables the probe wavelength to be chosen in a range for which suitable detectors are not available. To illustrate this, the researchers show images of objects that are either opaque or invisible to the detected photons. This experiment is a prototype in quantum information—knowledge can be extracted by, and about, a photon that is never detected.

Stone Soup
"Some travelers come to a village, carrying nothing more than an empty cooking pot. Upon their arrival, the villagers are unwilling to share any of their food stores with the hungry travelers. Then the travelers go to a stream and fill the pot with water, drop a large stone in it, and place it over a fire. One of the villagers becomes curious and asks what they are doing?. The travelers answer that they are making "stone soup", which tastes wonderful, although it still needs a little bit of garnish to improve the flavor, which they are missing. The villager does not mind parting with a few carrots to help them out, so that gets added to the soup. Another villager walks by, inquiring about the pot, and the travelers again mention their stone soup which has not reached its full potential yet. The villager hands them a little bit of seasoning to help them out. More and more villagers walk by, each adding another ingredient. Finally, a delicious and nourishing pot of soup is enjoyed by all." Wikipedia

The Disappearance Of The Instruction Manual

The Disappearance Of The Instruction Manual | Stone Soup | Scoop.it
Instructions not included: what the vanishing manual says about us
Donald Schwartz's insight:

"Short, succinct manuals allow the user to dive into many different tasks and to accomplish them quickly, thereby gaining a sense of control and autonomy that inspires further learning. "Skeptics would say we weren't providing the user with any theoretical foundation," Carroll says, “but we found that people got through their initial learning faster, and that later on, when they needed to learn more complex tasks, the users were also better at doing that, too.”


What is this guy talking about? My Nikon 810 came with a real manual which was virtually useable based of the way it's organized--the manual never finishes what you need to know to do "A", "B" or "C."  So I had buy a book to explain task-oriented procedures.

Funny Technology – Communauté – Google+

Funny Technology – Communauté – Google+ | Stone Soup | Scoop.it
Welcome to Funny Technology.

Community Rules | No Exceptions | Effective July 1, 2014

1. All posts must be in English.

2. Feel free to comment, re-share and plus one as often as you like.

3. No more than 6 posts per 24 hour period.

4. All posts must be both technology related & funny with the exception of the Suggested Themes posts that are published daily.

You do not have to stick to the theme(s) of the day. You must, however, keep your posts both technology related and funny.

5. The only exceptions are Daily Suggested Themes, Coffee, Cats, Dogs, Star Wars, Puns & Superheroes. Even these will be better received by the community if they are technology related.

6. In order to maintain some level of expectation:

Suggested Themes will continue to be posted daily.
Cats should be posted only on Saturdays
Dogs only on Fridays
Star Wars only on Tuesdays
Puns & Superheroes only on Sundays
Coffee, of course, any day.

7. The Category links in the left sidebar have been updated & alphabetized. If your category is not in the sidebar, don't post it.

8. The name of this community is Funny Technology for a reason. It's not called Tech News, Tech Products or Just Funny, so please don't post those, as they are most likely going to be removed.

9. Please do not post Tech News Tech Product News, or General Humor, as your post will be removed and you may be reported and banned from the community. There are many other communities for each of those.

10. Simply put, even if it's funny, do not post it if it's not technology related and included in the sidebar categories.

11. Off topic and non relevant posts will be deleted.

12. A complete list of categories for each day is published on the About page of my G+ personal profile. Link at the bottom.

13. Use the links in the left sidebar to bring up the categories you are most interested in, or just scroll down.

14. Animated Gifs & Videos are still welcome, but only if they fall under a category in the sidebar.

15. Do not reshare Funny Technology posts back into the Funny Technology Community, as they will be removed. Instead it makes much more sense to reshare Funny Technology posts on your G+ profile posts page.

16. This community does not discriminate based on race, sex or religion, nor does it endorse discrimination against any group of our fellow human beings. Posts that promote such an agenda should be reported immediately for removal. Thank you, as always, for your help and cooperation in keeping our community spam free.
