as we say, they're about never getting up every weekend on dw, the, to carbon neutral energy. new medicines to treat cancer are covered 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 acumen. as the most basic unit of quantum computing, the more to bits or 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 lab is run by german scientist hop was needing, widely recognized as

a pioneer in quantum computing. this somewhat remarkable building is where a hot was needing 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. it's a classic computer can let's thought was what a 2nd many, what degree is the most pressing problem of all times that this climate change would be marvelous to have an okay fusion reactor. now no k, a fusion reaction is when 2 nuclei which are both positively charged, come close enough together. so that's a snap together on form it. and you know, pills and is that in some energy is released some scientist how this could help

reduce greenhouse gas emissions. unlike traditional power plants, nuclear fusion does not release any carbon dioxide but um those 2 positive for each option. okay. yeah, they don't want to come close together as like as kits. we know when we have 2 magnets and that also the same polarity, they don't want to come close together. so is this process to properly model that i'm going to mechanical loss required? so it stands to reason is that credit and process so would help us. i'm hastens a design of you know, fusion reactor when quantum computers were still just a theoretical concept, parking needs 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, navy and 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 huntington even 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 the machine learning system to train in your network. for example, to recognize certain 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 efficiency. when the company intel presented the 1st quantum chip with 49 cubits with much fanfare in las vegas in 2019 leaving announced in a small block entry, that his team had already built

a chip with 72 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. hardwood nathan is a leading scientist in quantum physics. but that doesn't change the fact that it will take years until a workable point of computer will have been developed. the quantum computers can come to it's 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 do not 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 quantum computer is not a replacement for a regular computer. it's more of an assistance to the regular computer. i think a transportation analogy 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, as possibly revolutionary changes in, for example, materials development or pharmaceutical development. so the way you would 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 and 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 than 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 sensor complicated. check this out. laptops calculators for smartphones. they all use the information unit bit,

which can appear as either one or 0. quantum computers 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 bit 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 computer is 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 keep it can take on 4 and 22 bits can take on more than 1000000 quantum supremacy in 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 this warmest at the top and it gets colder as you go down. people often show pictures 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 g and 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 christ dot to reach the processor, interact with the coin and processor. and then the signal is up to come out again. and i'm responsible for getting that processor to be in 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 laws than normal computers, they are also extremely difficult to program. how do we control the control set 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 justina predicts that quantum computers will be used in about 5 to 10 years. but whether quantum ships will be used in the future is not just the question of technological progress, but have money to study by boston consulting group. has found that using quantum computers costs up 230025000 euros in our 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 live hill 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

much as to what did you do to save the tenants? she survived our shirts. thanks to music. was the nazis favorite conductor. he is martin, the, the genuine 2 musicians under the swastika documentary about this sounds of power inspiring story about survival of the home and you go get the tennis. i was the only one who lives in nazi germany. watch now on youtube dw documentary, i think i knew daniels and jen. you belong to the 77 percent to come to i just got on 65 last last those top 5 years, 3 reasons why one wants to see we are here to help you make up your mind. we are here on please find your mind. so talk to you from campbell talk, fixed

a new culture and in 15 minutes, let's say together parts of our community life on the surface of this research is now on the to this group is funding for some of the wells, rarest egg. they're searching for the endangered tv bugs of a, a tail roland you zealand to steal their eggs and save them from predators. almost 95 percent of teachers are killed in the wilds. if nothing is done, they will likely disappear. in new zealand record sales, kaylee would be pretty bad if we need. now national, there's thousands of people have joined

a massive program to defend the kiwi and kill their predators. they are showing what it takes for a country to protect its natural trojans. the deluxe hills of the current endo peninsula in new zealand, north island, a remarkable restitution is underway, giving signs of hope for an endangered national symbol. the key we few people f, a c, t we in the wild, rony kennedy has the encounter, motivated her to help save them from extinction. i have actually seen a key rate on a visit to the ceiling some years ago. it was amazing to see that tiny little.
