please. ah, free time in the line, but still very much alive. d. w, travel, your guide to the central southern germany a recognizes where exactly. it was fun. i learned a lot. our culture history. all their d. w. travel extremely worth a visit with 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. unsure,
7:17 pm
ah, 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 is the most basic unit of quantum computing. the more cubits a computer has, the more information it can process. many companies like i, b, m 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 lab in santa barbara in the u. s. and incredible experience outside the sun is

shining inside the lab. some areas have temperatures of minus $273.00 degrees celsius. the lab is run by german scientists. hot wouldn't even widely recognized as a pioneer in quantum computing. oh, is somewhat unworkable building is we're hot was mavin wants to revolutionize the tech world. it's located on a separate high security part of the university campus in santa barbara, california. here in the german scientist and head of google's quantum, a i lab, is working on a processor that could solve all the problems. a class a computer can't floods thought was what a thing many would agree, so most pressing problem of all times on his so climate change would be marvelous to a house. and okay, fusion reactor, no nuclear fusion reaction, is when 2 nuclei which are most positively cha, launched,
7:19 pm
come close enough together so that they snapped together on forming a new nucleus. and then some energy is released. some scientists hope that this could help reduce greenhouse gas emissions. unlike traditional power plants, nuclear fusion does not release any carbon dioxide. and those 2 positively charged nuclear, they don't wanna come close together as like as kits. we know when we have 2 magnets in other houses, same polarity, they don't want to come close together. so this process to properly model it, uncommon to mechanical laws are required. so it stands to reasons that m quentin processor would help us hastens the design of nuclear fusion reactor. when quantum computers were still just a few radical concept heartwood me than already believed in their potential. and his passion has convinced others after his doctor it he does research at
7:20 pm
one of the most renowned universities in the usa. mavin co founded 2 companies developing facial recognition technology. one of those companies was acquired by google and laid the foundation for google glasses. glasses with an integrated computer. in 2013 heart newton even started working on the quantity i lab for google. i have spent many years in the field of computer vision and machine learning to train a machine learning system to train a new or network, for example, to recognize certain objects in an image. you have to solve type of problems that's known as an optimization problem. and it has been proven analytically, that credit processes can solve these problems,

proficiency. when the company intel presented the 1st quantum ship of $49.00 cubits with much fanfare in las vegas in 2019, nathan announced in a small blog 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. heart newton even is a leading scientist in quantum physics. but that doesn't change the fact that it will take years until a workable quantum 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 justina, 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. 0, one on computer is not a replacement for a regular computer. it's more of an assistant to the regular computer. i to make a transportation analogy, when humans were wanting to travel to the moon, it was clear that you're, you need a rocket, you need some kind of technology that's different from what we used 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 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 effects. medicines could become more

efficient and affordable thanks to quantum computers. they can simulate molecular structures in a matter of seconds and 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 used the roles of quantum mechanics which apply to microcosmic process if the principle of quantum mechanics suggest that particles can exist in 2 separate
7:24 pm
locations at once. having the value of 0 and $1.00 sensor complicated, check this out, laptops, calculators, or smartphones. they all use the information unit bit, which can appear as either one or 0. quantum computers is 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
7:25 pm
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, 2 cubits can take on 4 and 20 cubits 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 cubit at quantum. a i lab to
7:26 pm
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. some system that looks like this, and i think i'll 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 as responsibility is to make sure that everything is connected properly. she runs the so called device packaging t in order to show that quantum effects, it has to be operated at very cold, dark environment, colder than outer space. and then we have to be able to send signals from room temperature electronics all the way into the christ. i to reach the processor, interact with the quantum processor, and then the signals up to come out again. and i'm responsible for getting that
7:27 pm
processor to be in a good environment where the cubits can operate at their potential job welding. the technology on to 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 signals 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 ambiguity in it, or sometimes a lot of ambiguities and you need them to all line up at the end and end god become a working functional system marissa justina 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
7:28 pm
a study by boston consulting group has found that using quantum computers costs up 230025000 euros 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 apart from tech companies states to are investing. china tops the table with 14000000000 euros, or than all other countries combined. one reason for estate interest and quantum computers is that they could hack into digital encryption methods. this would have consequences for crypto wallets, chats, health data and military tactics. what do you think? will quantum technology change your life? he'll illnesses or even flawed on 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 a soon,
