Is it sweet in fact, the most recent breakthrough? In quantum networking came from purdue university, where engineers have been working day and night on a method to fix a serious problem that stops the development of quantum networks large enough to reliably support several users, and you know what they finally made. Some massive headway. According to a recent report published by the researchers in optica, these engineers are laying the groundwork to create a series of quantum computers and quantum sensors that will have the ability to go online and successfully communicate with each other. The paper describes how a team of engineers have successfully deployed a programmable switch capable of adjusting the quantity of data sent to each user by choosing and redirecting certain wavelengths of light carrying data to different channels. This switch will make it possible to increase the number of users without having to endure photon loss, as the network expands in size. Yes, you might be surfing the web using quantum technology in the next few years, but photon loss is still a major problem that hinders this innovative technology because as soon as you lose photons in a fiber optic network, you’ve lost information. That being said, it’s not been an easy ride for the scientists that made this major breakthrough. According to andrew weiner, a distinguished professor of electrical and computer engineering at purdue, the team has had to undertake multiple daunting approaches that initially required them to physically interchange, dozens of fixed optical filters tuned to individual wavelengths.

This made it difficult to adjust connections between users and it also contributed to greater photon loss, but with the new method, scientists don’t have to worry about adding filters anytime, a new user joins a network. They simply programmed the wavelength selected through the switch to direct data carrying wavelengths to the new user, thereby minimizing operational costs and maintenance, as well as making quantum internet way more efficient. According to the paper, the wavelength switch was also able to alter the bandwidth depending on the user’s requirements, which was not the case for fixed optical filters. Some users were even able to access applications that require greater bandwidth than others, it’s kind of like how you can access more shows through a web streaming service. If you pay for a premium package to get higher bandwidth, pretty awesome right, but for quantum internet to work, forming connections between users and altering the bandwidth will require entanglement a process through which photons maintain a stable quantum mechanical relationship with each other. Regardless of the distance between them, this will enable users to successfully connect to a network, and so entanglement will be fundamental for quantum computing, as well as quantum information processing for the purdue researchers to create entanglement their method involved. Changing the rate at which the entangled photons were shared so that they could be used as a resource to entangle the quantum sensors and computers of two different users. While this is by all means impressive. One country has really outdone itself when it comes to photon entanglement, and that country is china.

As early as 2014, chinese scientists were able to achieve quantum entanglement to the distance of hundreds of miles thanks to the use of their miceas satellite. As for the purdue researchers they’re, presently working on building a much larger network using the wavelength selection switch, but this isn’t, the only quantum internet breakthrough that we’ve seen so far. In fact, in 2020, physicists at the delft university of technology in the netherlands have done something truly amazing, they’re, actually the first team in the entire world to successfully connect three quantum devices together and that’s huge according to the lead author of the study, dr ronald hansen. This is the first time that a network has been successfully created between quantum processors. Initially, a single direct link had been achieved between two processors in the past decade, but no network had ever been created, and so with the pace at which things are moving, one can’t help but continue to wonder just how will quantum internet affect the way i use The internet, well, the most immediate effect – would be enhanced security. You see, a set of entangled particles can be operated as a cryptic passcode that’s, because each particle in a quantum internet computer holds a qubit which is essentially the tiniest section of quantum computing information. It is shared only to its entangled twin found in the computer that you’re sending this information to. So a user will have the ability to encode their message as a string of qubits that only the receiving computer will be able to decode.

And if someone attempts to hack into the network and try to read the qubits from one of the computers, then, according to quantum mechanics, the user will be able to tell because the act of observing a particle changes, its quantum state in detectable ways. Now that would give hackers a hard time prowling in the shadows, wouldn’t it, but despite quantum internet seeming more secure than the current internet we have. It also has one major issue: it requires a lot more infrastructure to set up for a quantum connected future to be realized. We’Ll require multiple quantum computers, and these are really tough to design and build and let’s, also not forget that quantum relays are more difficult to set up than the relays we have with conventional internet. You see when it comes to quantum uplinks and downlinks. Each quantum signal relies on two entangled particles, interacting with each other across large distances between computers. This is really hard to pull off, because fiber optic cables begin destroying photons when a certain distance is crossed, plus these photons can’t travel across electrical wires. Also, once you read these photons, you can’t access new passcodes. Now, how do you solve this problem? Well, china seems to be on to something they’re tackling this problem by beaming entangled photons across hyper advanced relay stations based on earth through the mices satellite located in space. While it works it’s, not a hundred percent effective, because once you start reducing the precision of the transmitters, you gradually lose photons.

In fact, scientists are yet to come up with an ideal method of transmission that is cheap and reliable, but chances are that it’s going to involve a whole bunch of satellites, but other researchers have proposed a different solution to this problem. According to quantum physicist ronald hansen, people can still continue to use conventional computers. However, if they want to transmit a quantum secure message, they can simply head over to a local quantum relay and have it sent or they can easily connect to a secure online quantum computer. Through the internet and then send the message, this method would certainly cut down infrastructure costs. However, not every scientist is pumped and buzzed about the computing possibilities of a quantum internet. Scott aronson, a quantum computer scientist at mit, believes that quantum internet might disappoint the average internet user and it might not live up to their expectations. You see so many quantum physicists have marketed quantum computing as the dawn of a new era where man will be able to harness the untapped power of multiple universes and find out every solution. In parallel, quantum computing has been labeled as limitless, but most people will be shocked to find that quantum computers will only be good for a number of basic quantum simulations, not to mention possessing a few specialized features while they might someday lead to groundbreaking discoveries in fields Of medicine and technology, they might have very few immediate and transformative effects on the average person’s life according to aronson, the only major differences between a quantum connected internet and the current conventional internet we have today are very small and narrow the one major difference, as we Had mentioned earlier is that people will be able to relay their messages with a greater sense of security, far more advanced than what is available with our conventional internet.

They’Ll also have access to computers that’ll be able to carry out way more complex tasks at rates that are impossible. Today, a computer on the quantum web will most likely solve complex puzzles and patterns in seconds, one that could take the everyday computer several hours. We will most likely see computers that will be able to quickly optimize schedules for factory production or even figure out patterns in stock data within seconds, but bear in mind that all this is a big. If? Because no one really knows for sure just how fast the standard quantum computer will be, but you know what might be the biggest revolution from the birth of the quantum internet it’s, not even the quantum computers themselves, rather it’s. The secondary effects that quantum internet will have in important fields such as medicine and technology. We could see the development of better solar panels more effective medication, faster conventional computers and improved online service delivery. The possibilities could indeed be limitless across these fronts. In fact, we can honestly compare this present moment to the first days of research into computer networks that began in the 70s and 80s. You see we’re using computers in a totally different way than their intended use. Early on today, we use computers mostly to be a part of this massive online global village, where information is shared from every corner of the world. It’S likely that the same thing could happen with quantum internet. It might start out being used in one way and then transform into something entirely different, but as always it’s hard to predict the future.

But one thing’s for sure quantum internet will be a revolutionary technology and, with that being said, we’ve come to the end of this video. Let us know in the comments section down below what you think about quantum internet and how it might change our lives.
