What is quantum computing and why does the future of Earth depend on it?
Computing power is reaching a crisis point. If we continue to follow the trend in place since computers were introduced, by 2040, we will not have the capability to power all of the world’s machines, unless we can crack quantum computing.

Nearly a century after the dark matter was first proposed to explain the motion of galaxy clusters, physicists still have no idea what it’s made of.
Researchers around the world have built dozens of detectors in hopes of discovering dark matter. As a graduate student, I helped design and operate one of these detectors,... | <urn:uuid:a1355425-16da-4327-a627-aecb9eaacfe4> | CC-MAIN-2022-05 | https://www.inverse.com/science/dark-matter-quantum-mechanics | s3://commoncrawl/crawl-data/CC-MAIN-2022-05/segments/1642320304928.27/warc/CC-MAIN-20220126071320-20220126101320-00250.warc.gz | en | 0.925379 | 1,297 | 3.625 | 4 |

40 years ago, Nobel Prize-winner Richard Feynman argued that “nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical.” This was later perceived as a rallying cry for developing a quantum computer, leading to today’s rapid progress in the search for quantu... | <urn:uuid:d6d66360-ccb2-45e9-8a88-3ef00813f2a2> | CC-MAIN-2022-05 | https://www.forbes.com/sites/gilpress/2021/05/18/27-milestones-in-the-history-of-quantum-computing/ | s3://commoncrawl/crawl-data/CC-MAIN-2022-05/segments/1642320301475.82/warc/CC-MAIN-20220119155216-20220119185216-00691.warc.gz | en | 0.889865 | 1,155 | 3.671875 | 4 |
Light and matter are typically viewed as distinct entities that follow their own, unique rules. Matter has mass and typically exhibits interactions with other matter, while light is massless and does not interact with itself. Yet, wave-particle duality tells us that matter and light both act sometimes like particles, a... | <urn:uuid:8b769729-bc6f-451e-accf-640e09d25624> | CC-MAIN-2022-05 | https://news.uchicago.edu/story/uchicago-physicists-first-see-behavior-quantum-materials-curved-space | s3://commoncrawl/crawl-data/CC-MAIN-2022-05/segments/1642320305420.54/warc/CC-MAIN-20220128043801-20220128073801-00452.warc.gz | en | 0.935583 | 1,175 | 3.765625 | 4 |
Quantum teleportation is a technique for transferring quantum information from a sender at one location to a receiver some distance away.
While teleportation is portrayed in science fiction as a means to transfer physical objects from one location to the next, quantum teleportation only transfers quantum information.

Light and matter can interact in a number of different ways. Under certain conditions, light particles (photons) can affect the movement of atoms of matter. It happens because the emission and absorption of photons are followed by recoil. Such interactions are a study subject of one of the physics’ subdivisions, namely... | <urn:uuid:38c3c21b-c8ea-430b-b6fa-1111ef9820c5> | CC-MAIN-2022-05 | https://news.itmo.ru/en/science/photonics/news/10064/ | s3://commoncrawl/crawl-data/CC-MAIN-2022-05/segments/1642320305006.68/warc/CC-MAIN-20220126222652-20220127012652-00655.warc.gz | en | 0.940543 | 1,138 | 3.625 | 4 |

Physically, but not socially, isolated: Insights from a small Micronesian island (Eileen Tipoe, Economics)
The small Micronesian island of Yap is both geographically and economically isolated.

In the last post, we described what qubits are and how quantum computing involves the manipulation of these qubits to perform useful calculations.
In this post, we’ll abstract away from the details of the physics of qubits and just call the two observable states |0⟩ and |1⟩, rather than |ON⟩ and |OFF⟩. This will be use... | <urn:uuid:9a27c6e0-42b2-47e7-85c3-8c800018042a> | CC-MAIN-2022-05 | https://risingentropy.com/more-on-quantum-gates/ | s3://commoncrawl/crawl-data/CC-MAIN-2022-05/segments/1642320301063.81/warc/CC-MAIN-20220118213028-20220119003028-00016.warc.gz | en | 0.930639 | 1,036 | 3.90625 | 4 |
If we provide a bog-standard computer with an infinite data store, it suddenly becomes a Turing machine: capable of answering any question answerable by any digital computer. Even quantum computers are no more powerful; they are merely faster. For example, a quantum computer recently factorised 15 into 5 * 3 by using S... | <urn:uuid:1033f30a-f763-46d0-990b-5ac546789707> | CC-MAIN-2022-05 | https://cp4space.hatsya.com/2012/09/14/linear-bounded-automata/ | s3://commoncrawl/crawl-data/CC-MAIN-2022-05/segments/1642320304876.16/warc/CC-MAIN-20220125220353-20220126010353-00416.warc.gz | en | 0.937257 | 1,695 | 4 | 4 |
