Besides that, I think it would be good if journalists writing about this stuff would just ask people making such claims “and then what?”. I mean, let’s assume for a moment we actually manage to build a 7000 logical qubit quantum computer and actually simulate Maldacena’s whatever model on it. And then what? They’ll write papers and press releases. And then what? What will we learn from it? What will we do with it? Gard, Bryan T.; Motes, Keith R.; Olson, Jonathan P.; Rohde, Peter P.; Dowling, Jonathan P.

Fundamentally, you might think Quantum could improve every scientific and technological endeavour, but that would be fallacious. We only know of specific algorithms that are theoretically amenable to being sped up or enhanced by quantum algorithms. There is even a quantum zoo of algorithms highlighting quantum algorithms and their potential speed-ups.

Success!

The first couple chapters are about the history of computers and I found that boring because it was stuff I already knew. I enjoyed much more learning how quantum computers work and the specifics of how they could solve many real-world problems. So what is it that makes quantum computers so powerful? Well, two key factors contribute to this power. The JSESSIONID cookie is used by New Relic to store a session identifier so that New Relic can monitor session counts for an application. Me, after a long while: This has been quite interesting. But I would still like to understand how quantum computation--

When tediously computing the paths taken by a mouse in a maze, a digital computer has to painfully analyze each possible path, one after the other. A quantum computer, however, simultaneously analyzes all possible paths at the same time." a b Aaronson, Scott; Arkhipov, Alex (2011). "The computational complexity of linear optics".

S2CID 681637.On June 18, 2019, Quanta Magazine suggested that quantum supremacy could happen in 2019, according to Neven's law. [35] On September 20, 2019, the Financial Times reported that "Google claims to have reached quantum supremacy with an array of 54 qubits out of which 53 were functional, which were used to perform a series of operations in 200 seconds that would take a supercomputer about 10,000 years to complete". [36] [37] On October 23, Google officially confirmed the claims. [38] [39] [40] IBM responded by suggesting some of the claims are excessive and suggested that it could take 2.5 days instead of 10,000 years, listing techniques that a classical supercomputer may use to maximize computing speed. IBM's response is relevant as the most powerful supercomputer at the time, Summit, was made by IBM. [41] [16] [42] Researchers have since developed better algorithms for the sampling problem used to claim quantum supremacy, giving substantial reductions to the gap between Sycamore and classical supercomputers [43] [44] [45] and even beating it. [46] [47] [48] This is justified by a bizarre paragraph about lattice gauge theory, which explains that since we can’t solve QCD analytically, here’s what theorists do: In the future, researchers may find more uses for quantum computers, but we, as responsible scientists, must be mindful of the hype surrounding Quantum Computing. We have to be careful that quantum computing does not get over-promised and under-delivered. It is not a general computing technique. Now is the time to experiment, play and develop some of the foundations of quantum technology without excessive expectations. Knapton, Sarah (2019-12-17). "Academics derided for claiming 'quantum supremacy' is a racist and colonialist term". The Telegraph. ISSN 0307-1235 . Retrieved 2019-12-21. You’ll probably never have a quantum chip in your laptop or smartphone. There’s not going to be an iPhone Q. Quantum computers have been theorised about for decades, but the reason it’s taken so long for them to arrive is that they’re incredibly sensitive to interference.

It's a fun book on one hand, but annoying on the other. All those "mights" and "mays" about drove me nuts. He discusses why our current supercomputers are unable to solve these problems and how quantum computers could. He breaks the problems down to their molecular levels to show how they could be solved with enough computational power. Quantum computing enjoyed a relatively tranquil start to the year as generative artificial intelligence overshadowed quantum in technology media. Fundamentally, this was a good thing—getting out of the spotlight gives researchers and startups valuable time to focus, rather than spending time fighting misconceptions. Michio Kaku’s new book “Quantum Supremacy,” and the media tour to promote it, recycles multiple talking points long since debunked within the quantum community and introduces new claims that are equally, if not more, specious.

In 1994, further progress toward quantum supremacy was made when Peter Shor formulated Shor's algorithm, streamlining a method for factoring integers in polynomial time. [22] Later on in 1995, Christopher Monroe and David Wineland published their paper, “Demonstration of a Fundamental Quantum Logic Gate”, [23] marking the first demonstration of a quantum logic gate, specifically the two-bit " controlled-NOT". In 1996, Lov Grover put into motion an interest in fabricating a quantum computer after publishing his algorithm, Grover's Algorithm, in his paper, “A fast quantum mechanical algorithm for database search”. [24] In 1998, Jonathan A. Jones and Michele Mosca published “Implementation of a Quantum Algorithm to Solve Deutsch's Problem on a Nuclear Magnetic Resonance Quantum Computer”, [25] marking the first demonstration of a quantum algorithm.
