It would certainly be amazing, but is it actually feasible?<\/p>\n<p>Quantum computers are ludicrously complex, but they can be explained with relative ease. In order to build one you have to overcome environmental factors such as keeping them extremely cold and figuring out how to keep qubits \u2013 the quantum version of a computer bit \u2013 from becoming decoherent and unmeasurable.<\/p>\n<p>These are difficult challenges that exist at the very edge of scientific exploration in the realms of engineering and physics.<\/p>\n<p>Currently, the two most popular examples of a \u201cfunctioning\u201d quantum computer are IBM\u2019s 65-qubit system and Google\u2019s own 72-qubit Bristlecone system.<\/p>\n<p>These systems are sort of like the giant mainframes of yesteryear, except they use far too much power to be useful, they\u2019re incredibly prone to errors, and the only things we can really get them to do are experiments designed to show what future usefulness could look like.<\/p>\n<p>Getting from there to something that\u2019s not only functional, but capable of performing truly useful feats better than any existing <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">technology<\/a>, seems like something that could take decades.<\/p>\n<p>Per <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/blog.google\/technology\/ai\/unveiling-our-new-quantum-ai-campus\/\">a blog post<\/a> from Google:<\/p>\n<blockquote><p>To reach this goal, we\u2019re on a journey to build 1,000,000 physical qubits that work in concert inside a room-sized error-corrected quantum computer. That\u2019s a big leap from today\u2019s modestly-sized systems of fewer than 100 qubits.<\/p>\n<\/blockquote>\n<p>Google\u2019s been known to be a bit hyperbolic when it comes to quantum computing. In 2019 Google and NASA claimed they\u2019d achieved \u201cquantum supremacy\u201d by developing a quantum computing system that could solve a problem in a matter of minutes that would take a classical computer \u201c10,000 years\u201d to solve.<\/p>\n<p><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.technologyreview.com\/2020\/02\/26\/905777\/google-ibm-quantum-supremacy-computing-feud\/\">It turns out<\/a>, the supercomputer they were talking about was an IBM device and Big Blue claims that it can actually solve the problem Google is talking about in a couple of days if you use it right. That\u2019s a bit embarassing for Google, as 10,000 years and 48 hours are pretty far apart.<\/p>\n<p>So it\u2019s worth taking things with a grain of salt when Big G says it\u2019ll create a one-million-qubit computer in the same time-frame it takes Rockstar <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/game\/\" data-internallinksmanager029f6b8e52c=\"7\" title=\"Game\" target=\"_blank\" rel=\"noopener\">Game<\/a>s to develop a <i>Grand Theft Auto<\/i> game.<\/p>\n<p>However, Google isn\u2019t just hoping that if it builds a big lab the qubits will come. It has a rather innovative plan to scale things up so quickly.<\/p>\n<p>Per the blog post:<\/p>\n<blockquote>\n<p>To get there, we must build the world\u2019s first \u201cquantum transistor\u201d \u2014 two error-corrected \u201clogical qubits\u201d performing quantum operations together \u2014 and then figure out how to tile hundreds to thousands of them to form the error-corrected quantum computer. That will take years.<\/p>\n<p>To get there, we need to show we can encode one logical qubit \u2014 with 1,000 physical qubits. Using quantum error-correction, these physical qubits work together to form a long-lived nearly perfect qubit \u2014 a forever qubit that maintains coherence until power is removed, ushering in the digital era of quantum computing. Again, we expect years of concerted development to achieve this goal.<\/p>\n<p>And to get THERE(!), we need to show that the more physical qubits participate in error correction, the more you can cut down on errors in the first place \u2014 this is a crucial step given how error-prone physical qubits are.<\/p>\n<\/blockquote>\n<p>This is the first time we\u2019ve heard the term \u201cforever qubit\u201d here at Neural, and it\u2019s unclear if this a goal\u00a0post-moving way of describing a hybrid quantum computing system that\u2019s functionally a wacky classical system. But, if you take the whole blog post at face value\u2026<\/p>\n<p>There\u2019s still simply no telling whether Google\u2019s 50 years way from a useful quantum system or five.<\/p>\n<p>It\u2019ll be exciting to follow along and, hopefully, as the research papers come out, we\u2019ll get a better idea of what these \u201cforever qubits\u201d mean for the field.<\/p>\n<p>Don\u2019t forget to check out the rest of our Google I\/O coverage right here.<\/p>\n<\/div>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
