Schrödinger's Cat, Virtual Data and Teleported Hard Drives
- Did you see what direction they were going?
- They've moved towards the valley. There is a plain behind the hills.
- Mr. When Spock is awake, teleport him to the Enterprise.
- If you don't get a signal from me for 12 hours ...
Along with this unforgettable dialogue, I must say that one of the indispensable works of many Science Fiction fans is Star Trek. Of course, this series, where we met teleportation, has a completely different place for me. However, the example I have given, of course, does not have much to do with our topic. Our title does not talk about teleporting in the way we all know. We will not be teleported in by opening the sliding door in the shower cabin style, but what would your reaction be, if we said that the internet we all use every day will have such a feature? Of course I do not say this, but the subject that Australian and Japanese scientists are working on says that they are willing to do this. First of all, let's take a brief look at what the terms in our title are and then let's teleport.
Of course, the most famous cat after Garfield, our cute, mischievous and lazy cat, is Schrödinger's cat. But what is this cat doing in the scientific arena where so many complex formulas and thousands of scientists have been pondering and experimenting for years. This experiment, which was put forward by the famous scientist Schrödinger in the 1930s, was originally proposed to make fun of Quantum theories, but later made significant contributions to the Quantum world. To summarize, a live cat is placed in a sealed box. Inside the box is a radioactive material and a Geiger counter to measure this activity. If the Geiger counter observes any radioactive movement, it will emit cyanide inside the can and the cat will die. Since the box is sealed and closed, learning whether the cat is alive depends on the observer opening the box, so we do not know whether the cat is alive or dead without opening the box, and we consider the cat both alive and dead. This situation is called superposition. Since we have summarized this subject briefly, let's talk about virtual data and hard disks. Please stay with us, but our cat will be back in business soon.
Virtual Data, Microprocessors and Hard Disks
Computer technologies, which are indispensable for human beings, are developing day by day. Well, let's talk about how these systems work first. To put it simply, a computer has 3 most important units during a process. These are microprocessor, ram and hard disk. The microprocessor reads a collection of bytes (bytes here is our data) from RAM (instruction fetch). It then interprets which command this collection of bytes is and runs the electronic circuits to execute this command. And by going back to the first step, we can perform some of our transactions thanks to this cycle.
You can take a look at my Microprocessors article to examine microprocessors and their operating systems in more detail. Finally, let's look at how this read data is processed on the hard disk and continue our topic. There is a magnetic disk in the hard disk for processing data and the information is processed in the small holes in this disk. The reading and writing ends of the hard disk play a role in reading or writing the information.
Let's continue in the light of our short information without further distracting our topic. We all have memories of the oddities we have experienced in the past when connecting with 56K modems. We could not talk to our friend on the home phone and connect to the internet at the same time, and we could not stay connected every minute. However, today, with the development and widespread use of ADSL, the widespread use of 3G systems in our country, the development of search engines such as Google, Bing, Yandex, and smart phones, we have the freedom to access the internet from wherever we want, and do research at any time. However, we are still faced with the limitations of our internet speed. When you urgently need to send a very important company software, you can get stuck in many obstacles such as the quality of your servers, the quality of your internet infrastructure, the type of cable you use. Or if you are a home user, we have to wait while downloading a game or movie you bought from the internet, depending on our internet speed and the conditions I mentioned. Especially if you are a Blu-Ray patient like me, you may have to wait a long time to watch movies ranging from 10 gigabytes to 40 gigabytes. What if we never had to wait? What if this virtual data could be teleported to our computer with one click of us?
Virtual Data and Teleported Hard Disks
We can now get back to the cat and superposition we mentioned at the beginning of our article. I am of the opinion that this leap in the information age (hopefully in 10-20 years) will take us beyond the space age. Although this futuristic idea seems to be cut off from science fiction movies, this futuristic idea is now in the research phase and some developments have taken place. Now, the bit system is replaced by qubits. As it is known, a bit has a value of 1 or 0 and these bits combine to form our data. However, as in the superposition, qubits have many states between 0 and 1, although they have 1 and 0 at the same time. Currently, our classic method is to provide transmission with copper or fiber optic cables, but the system that will provide this beaming is a common source between the receiver and the sender at any time in the past. And going back to our cat, if a macroscopic object can be observed as a quantum superposition. Employees of the Faculty of Engineering and Information Technology in Canberra announced that they were able to teleport a macroscopic light wave from one point to another while in an extremely sensitive quantum superposition. In addition, this digital information can be encoded according to the state it is in. In other words, this data is a wave packet with the value of both "1" and "0". In the statements made, it was stated that these developments will pave the way for quantum computers. Since this wave packet carries the values of "1" and "0" at the same time, it enables parallel processing. After I present some research and results, I would like to add a few things. In the light of the studies, one day we will neither calculate our internet speed nor wait to reach the data. This sweet cat will step in and beam the data to us. Although it looks futuristic, research shows that these may be possible in the future. So our job is to follow these developments with great enthusiasm and buy ourselves a hard disk with plenty of terabytes and a mouse with a long click life. As I conclude our article, I salute Vulcan saying “Live long and prosper”.
