see more to offer. right, that's all the news for this out. out. technology show shift is up next. taking a look at quantum computers that's coming up after short break. vermont is that the youtube channel is a great place to catch up with overlay the state of new coverage loc was the website to be found at dw delta. com for me and the team here in berlin will have more news for you. and 45 minutes talks type the fast fashion as an environmental 9, a clothing graveyard in the to land desert. this is where things wealthy industrial nations no longer need and light us textile ways get stranded fashion. watch now on youtube. it shouldn't be this

warm here. it's hard not to feel something really is happening here. what is happening to greens and ice? explore an untouched place into the ice starts january dw, carbon neutral energy, new medicines to truth, cancer or cove. it and foldable screens. thanks to quantum computers, these could be innovations of the future. for years, scientists have been confident that these processors will be the next big tech revolution. but how far have developers really come? and what can we gain quantum computers? that's our topic today on shift the

quantum computers won't be replacing our laptops or smartphones, but apart from developing new medicines and materials. i think one aspect is especially interesting. quantum computers can perform complex simulations, like predicting extreme weather very accurately across the globe. developers are trying to create computers with the highest amount of cubits a cubit as the most basic unit of quantum computing, the more cubits are computer, has the more information it can process. many companies like ibm and google are competing to develop the most advanced quantum computer. google's quantum computer recently simulated a warm hole, the holy grail and physics. so what are they doing in these quantum laps? after sending countless e mails, we were finally able to visit the google quantum a. i live in santa barbara in the us and incredible experience outside the sun is shining inside the left. some areas have temperatures of minus $273.00 degrees

celsius. the lamp is run by german scientist happened with newton, widely recognized as a pioneer in quantum computing. this somewhat and remarkable building is where hot needs and wants to revolutionize the tech world. it's located on a separate high security part of the university campus in santa barbara, california. here the german scientist and head of google's quantum and i lab is working in a process would that could solve all the problems big class the computer can't. let's start with what i think many would agree as the most pressing problem of all times that this climate change would be marvelous to have a new care fusion reactor. now, nuclear fusion reaction is when 2 nuclei, which i'm most positively charged, come close enough together. so that's a snap together on the form in the nuno pills and to is that in some energy is

really some scientist that this could help reduce greenhouse gas emissions. on with traditional power plants, nuclear fusion does not release any carbon dioxide on those 2 positive feet. charge ok, they don't want to come close together as like as kids to be know when we have 2 magnets in the same polarity, they don't want to come close together. so this process to properly model that kind of mechanical laws are required. so it stands to reasons that credit and process so would help us and hastens the design of you know, fusion reactor when quantum computers were still just a theoretical concept, harkey need and already believed in their potential. and his passion has convinced others after his doctor it he does research at one of the most renowned universities in the usa. nathan co founded 2 companies developing facial

recognition technology. one of those companies was acquired by google and lead the foundation for google glasses. glasses with an integrated computer in 2013 hardly. nathan started working on the quantum a lab for google. i have spent many years in the field of computer vision and machine learning to train machine learning system to train in your network, for example, to recognize objects in an image. you have to solve the type of problems that's known as an optimization problem. and it has been proven analytically set funding processes can solve these problems more efficient when the company entail presented the 1st quantum chip with 49 cubits, with much fanfare in las vegas. 2019. nathan announced in

a small blog entry that his team had already built a chip with $72.00 cubits. shortly thereafter, he claimed to have proven the functionality of the google quantum computer. 200 seconds for a computational task that would take 10000 years on a super computer, ibm and many others are doubtful. pardon me, nathan is a leading scientist in quantum physics. but that doesn't change the fact that it will taking years until a workable point of computer will have been developed. quantum computers can compute very quickly, but there aren't many practical ways to use them yet. they're also prone to errors and programming and production is very complex. quantum electronics engineer marissa, just doing that, explains what these computers could mean for the future. quantum computers won't replace laptops or pcs, but they will assist them. you probably won't see it much in your day to day life.

so i'm wondering, computer is not a replacement for a regular computer. it's more of an assistance to the regular computer. i think of transportation technology, when humans were wanting to travel to the moon, it is clear that you're in need a rocket. you need some kind of technology that's different from what we use to get around on the ground. now we have this technology is, it does not change the way you go to the grocery store. so similarly, having a quantum computer will not likely change the way you do your day to day activities . but it will be a research tool that allows for, or possibly revolutionary changes in, for example, materials development or pharmaceutical development. so the way you will experience it more would be kind of the 2nd level effect medicine. so could become more efficient and affordable thanks to quantum computers. they can simulate molecular

structures in a matter of seconds. and to calculate the combination of active ingredients, which could replace testing them in laboratories. this would enable pharmaceutical companies to develop and release medicines much faster. we can also benefit from quantum computers when it comes to traffic. the quantum computers are able to process very large amounts of data in seconds. they could calculate routes, taking traffic lights and speed limits into account keeping traffic flowing. future quantum computers will be good at testing many different scenarios to find the best one. why are they more efficient at this then so called super computers? well, they use the roles of quantum mechanics which apply to microcosmic processes. the principle of quantum mechanics suggest that particles can exist in 2 separate locations at once, having the value of 0 and $1.00. it's also complicated. check this out. the

laptops, calculators, or smartphones. they all use the information unit bit which can appear as either one or 0 quantum computers and use the laws of quantum physics instead and work with quantum bits or cubits. rather than switching between 0 and one cubits can be both simultaneously or appear as something in between. this principle is called superposition and can be explained by using coins to represent one but heads or tails need to be on top. it's clear one or 0 to represent a cubit to the coin rotates rather than being limited to either being heads or tails. the coin is both quantum computers can calculate simultaneously where conventional computers calculate sequentially. this makes quantum processors fast and efficient more cubits mean more computing power. this computing power rises

exponentially according to the number of possible states. one cubic can take on 2 values simultaneously to cupids, can take on 4 and 22 bits can take on more than 1000000 quantum supremacy and tech circles. that's what they called a point in time. when quantum computers will have overtaken super computers, scientists around the world are competing to create chips with the highest amount of cubits. the technological challenges are huge. so far google's quantum computers only work and lab conditions, and extremely cold temperatures, and isolated from the environment. quantum electronics engineer marissa justina, is responsible for creating ideal conditions for the cubits at quantum a lab. so this hardware actually is just a refrigerator, it's warmest at the top and it gets colder as you go down. people often show

pictures of, of some system that looks like this and then go look at that big quantum computer. actually, the only thing that's quantum in there is the small silicon chip which is down inside some layers of packaging in here. the quantum chip is just as big as a finger. now, it sits at the bottom of this nearly 2 meter long construction of cables, metal sheets, and conductors. marissa justine is responsibility is to make sure that everything is connected properly. she runs the so called device package of gene in order to show that the content effect it has to be operated as very cold, dark environment for colder than the outer space. and then we have to be able to send signals from room temperature electronics all the way into the credit start to reach the processor, interact with the quantum processor. and then the signal is up to come out again. and i'm responsible for getting that processor to be in a good environment where the cubits can operate at their potential welding the

technology onto the chip requires clinical precision. and building quantum computers has more challenges. since they use different logs than normal computers, they are also extremely difficult to program. how do we control the controls that goals that we send in? how do we make sense of the measurement signals we get out and use them? there are a number of different technology areas that we need to develop, each of which has a little bit of, of antiquity in it. or sometimes a lot of them to do it is, and you need them to all line up at the end and, and become a working functional system. marissa justine, it predicts that quantum computers will be used in about 5 to 10 years. but whether quantum chips will be used in the future is not just a question of technological progress, but of money to a study by boston consulting group has found that using quantum computers costs up

to $3000.00 since of 5000 years as an hour. by comparison, using a traditional cloud computer costs less than a cent per hour. another interesting aspect is who invests and quantum research, a part from tech companies states to are investing. china tops the table with 14000000000 zeroes, or then all other countries combined. one reason for state interest in quantum computers is that they could hack into a digital encryption method. this would have consequences for crypto wallets, chaps, health data and military tactics. what do you think? will quantum technology change or lives he'll illnesses or even slow down climate change? i'm curious to see which areas will make a quantum leap. and what that means for us, we'd love to hear from you for now by and see you soon. the

bad why are you some wonderful people sing about to get inspired by your them use for the beats and group try to help us artist many of whom never truly lead me on this that is not made of plastic. this bag is made for me to pull some is in bangladesh, it promises an economic pool. and so the load potential future without plastic but processing to, to is expensive, complex and time consuming. so what's the low down on the golden natural?
