manipulate 2 states at the same time. If a quantum computer can manipulate n qubits at the same time, it can actually manipulate 2N states at the same time, each of which is a n-bit classic bit.This is the parallel computing power of quantum computer lore.Finally, let's use the Grover algorithm of quantum computation to illustrate how it is computed in parallel.

Quantum computers can filter large amounts of data more efficiently and quickly than ordinary computers or humans, and make further data analysis within the relevant information available, and it can throw away information that is of little use and enhance the extended analysis of leading data information. In May 2013, Google, NASA and the United States University Space Research consortium bought the second generation of

not good stars, and "Schrödinger's cat" must be the most famous pet in the scientific community. Quantum superposition states that the cat is in a state of birth and death, and it is this one that gives the public a perceptual understanding of the metaphysical and metaphysical quantum theory.In fact, the computational principle of quantum computers is the same a

that you can put a quantum bit of information into a superposition state, and you can imagine a situation in which qubits have not decided what they want to call the state. Some people like to think of this superposition state as "having two states at the same time." Or you can think of the state of the qubit as not deciding whether to choose +1 or-1. This means that if a

Introduction If I read the first article of the [quantum computing] quantum computing commonly used high-frequency word collection students should feel very puzzled, what is the superposition state is a ghost.According to the above explanation:State superposition principle (superposition principle): If the quantum state of a

In this major, I have been fortunate to hear that the group of their experiments will come to (CHE) to answer (Dan) a bit.Before the Chaoyang Lu Group in the group will be in the time of the brother is doing this, I am a professional undergraduate, before I saw them paper hair, there are news, but also with roommates vomit slot. But the experiment itself is OK, Zhong Ke in t

Wen/Li Bo (Guang Yu guangzhen) The best and most critical property of quantum physics is "randomness", which is the "essence" attribute of quantum physics (fundamental,Intrinsic randomness ). The greatest randomness is the maximum amount of information. In the application of quantum information, "dequantization" cannot deduct two "randomness" derived from BB84-t

Google released 72-bit quantum computers. Will bitcoin be safe? At the annual meeting of the US physics conference held in Los Angeles this year, Google launched the world's first 72-bit quantum computer, Bristlecon, to achieve a low error rate of 1%, it is the same as Google's previous 9-bit quantum computers. This processor not only helps scientists explore

Introduction to Quantum computing This document translates D-ware Company's "Quantum Computing Primer", which existing deficiencies or errors are welcome to point out. Original source: https://www.dwavesys.com/tutorials/background-reading-series/quantum-computing-primer#h1-0 The purpose of this tutorial is to introduce the concepts and terminology used in

Http://news.cnblogs.com/n/509750/(Shell Translation Learning Group/translation) The gist of the most famous thought experiment in quantum mechanics is that the quantum world is completely different from the world we know. Austrian physicist Erwin Schrodinger (Erwin Schrödinger) Let's imagine a cat in a box. The cat's fate is closely linked to the quantum world, w

----turn from your own circle of friendsThis year has been a lot of hype about quantum communications, among which the analyst's articles are riddled with errors, and can only be fooled by investors. I will not refute those mistakes, and the real technician can see them at a glance.I have a lot of friends in the Circle of communication, network security experts, I will tell you my opinion, please correct me. In a word: "Out of the military, no one wil

1, "an electron will pass through two slits at the same time." "Electronic double-slit interference experiment has been nearly hundred years, its behind the microscopic world of physics has been well known, quantum mechanics has also undergone a variety of other experimental tests, the current expansion and application of it is endless. However, because ordinary people's so-called "intuitive understanding" of the deviation and physics itself on the in

Quantum computing has always been confusing. You need to read a lot of technical materials to understand this technology. However, quantum technology may become a reality within ten years, which will have a huge impact on the industry. Currently, most encryption algorithms (especially public and private keys) are feasible because their mathematics makes it difficult for conventional (non-

Quantum Theory Quantum Theory is obviously the most cutting-edge theory in the 21st century. Its Influence covers all aspects of human civilization, and even includes philosophy and culture. The classic materialism or idealism we have known have gradually blurred the margin after quantum theory. Our understanding of history, our understanding of matter, and our u

A team of researchers from South Africa recently successfully ran the Simon's algorithm on a quantum computer, and the algorithm performed better on a quantum computer than an electronic one. The relevant papers are published in the Physical Review Letters. A quantum computer is a quantum-mechanical computing device th

In order to reconstruct their own knowledge system, this period of time to fill a bit of scientific knowledge. Yesterday in the library borrowed this "quantum mystery", this book is well written, translation is also good. Basically, bang read it out. After reading the book, we have to summarize:1) for "Schrödinger's Cat":The quantum is in the superposition state (the cat is dead and alive at the same time),

http://news.cnblogs.com/n/193989/ The quantum anomaly Hall effect, for ordinary people, is clumsy and obscure. But in the eyes of physicists, it is "magical" and "wonderful". Because its discovery could lead to the next information technology revolution. Using this technology to design integrated circuits and components, the China supercomputer is expected to be as big as a tablet computer, and smartphone memory may be raised by hundreds of thousands

Ainemo has heard of scalar quantum queries before, but its understanding of the details is far from enough. It makes a simple analysis and introduction to scalar quantum queries through some materials and self-testing. Oracle allows a single-row subquery to be included in the select clause. This is the oracle scalar quantum query. The scalar

In the field of display technology, color display precision and color display equipment are the two most important focal points. From the early CRT spherical display and the bitmap display state stage, to the current formation of curved screen and quantum dot display technology industry trends, is the entire display area experienced a huge development stage. Especially at present, a series of "quantum dots
