entanglement
I got into this stuff because of science fiction. I was a huge nerd in high school. I remember there was a time that between UPN, TNN, and The SciFi Channel you could watch six straight hours of Star Trek on a Friday night. None of those networks exist anymore. I built a Stargate in my parents’ basement freshman year (see above)--though I never got it to send me anywhere. When my Junior English teacher told me to write a paper on John Steinbeck, F. Scott Fitzgerald, or another famous American author, I wrote it on Phillip K. Dick.
As I grew older, and my knowledge of science fact began to…
There have been a bunch of stories recently talking about quantum effects at room temperature-- one, about coherent transport in photosynthesis , even escaped the science blogosphere. They've mostly said similar things, but Thursday's ArxivBlog entry had a particular description of a paper about entanglement effects that is worth unpacking:
Entanglement is a strange and fragile thing. Sneeze and it vanishes. The problem is that entanglement is destroyed by any interaction with the environment and these interactions are hard to prevent. So physicists have only ever been able to study and…
To follow up on the faster than light post here, let's ask another question:
If you can make a way of transferring information that doesn't involve matter, is that information limited by the speed of light?
First off, let's go over what information is, and then we'll talk about how transferring information without matter is even possible. Information is anything that's organized in a meaningful manner. Take a look at the following three sentences:
This sentence contains some information.
