Does quantum computing really exist? It’s fitting that for decades this field has been haunted by the fundamental uncertainty of whether it would, eventually, prove to be a wild goose chase. But Google has collapsed this nagging superposition with research not just demonstrating what’s called “quantum supremacy,” but more importantly showing that this also is only the very beginning of what quantum computers will eventually be capable of.

This is by all indications an important point in computing, but it is also very esoteric and technical in many ways. Consider, however, that in the 60s, the decision to build computers with electronic transistors must have seemed rather an esoteric point as well. Yet that was in a way the catalyst for the entire Information Age.

Most of us were not lucky enough to be involved with that decision or to understand why it was important at the time. We are lucky enough to be here now — but understanding takes a bit of explanation. The best place to start is perhaps with computing and physics pioneers Alan Turing and Richard Feynman.

Physicists can explore tailored physical systems to rapidly solve challenging computational tasks by developing spin simulators, combinatorial optimization and focusing light through scattering media. In a new report on Science Advances, C. Tradonsky and a group of researchers in the Departments of Physics in Israel and India addressed the phase retrieval problem by reconstructing an object from its scattered intensity distribution. The experimental process addressed an existing problem in disciplines ranging from X-ray imaging to astrophysics that lack techniques to reconstruct an object of interest, where scientists typically use indirect iterative algorithms that are inherently slow.

In the new optical approach, Tradonsky et al conversely used a digital degenerate cavity laser (DDCL) mode to rapidly and efficiently reconstruct the object of interest. The experimental results suggested that the gain competition between the many lasing modes acted as a highly parallel computer to rapidly dissolve the phase retrieval problem. The approach applies to two-dimensional (2-D) objects with known compact support and complex-valued objects, to generalize imaging through scattering media, while accomplishing other challenging computational tasks.

To calculate the intensity distribution of light scattered far from an unknown object relatively easily, researchers can compute the source of the absolute value of an object’s Fourier transform. The reconstruction of an object from its scattered intensity distribution is, however, ill-posed, since phase information can be lost and diverse phase distributions in the work can result in different reconstructions. Scientists must therefore obtain prior information about an object’s shape, positivity, spatial symmetry or sparsity for more precise object reconstructions. Such examples are found in astronomy, short-pulse characterization studies, X-ray diffraction, radar detection, speech recognition and when imaging across turbid media. During the reconstruction of objects with a finite extent (compact support), researchers offer a unique solution to the phase retrieval problem, as long as they model the same scattered intensity at a sufficiently higher resolution.

“If you are not convinced by the idea of reductive materialists that consciousness magically emerges from complexity in material structures or processes or if you are not satisfied with the viewpoint of idealists that matter is a mere thought form, then the present hypothesis may be something for you,” writes Dr. Antonin Tuynman when presenting his new book The Ouroboros Code. https://www.ecstadelic.net/top-stories/the-ouroboros-code-self-reference-is-the-name-of-the-game #OuroborosCode

In “The Ouroboros Code” I will address the cybernetic dynamics of consciousness. Starting from the premise that Consciousness is the Ontological Primitive, I will propose mechanisms which may explain how a digital mathematical and material existence can be generated. Digging into Category Theory, Computational Simulacra and Quantum Computing, I will explore the mechanics of self-sustaining self-referential feedback loops as the Modus Operandi of Consciousness.

Let’s dive in the vortex of kaleidoscopic reflections, the wormhole of a dazzling “mise-en abyme” of recursiveness and the roller-coaster of the quantum non-locality. Explore the map which is the territory simultaneously by drawing your map of maps. Discover the non-dual bridge closing the gap between Science and Spirituality.

Reader, Tamia Boyden asks this question:

In the 90s, how could we access the internet without WiFi?

This post began as an answer to that question at Quora. In the process of answering, I compiled this history of public, residential Internet access. Whether you lived through this fascinating social and technical upheaval or simply want to explore the roots of a booming social phenomenon, I hope you will find the timeline and evolution as interesting as I do.

I have included my answer to Tamia’s question, below. But first, let’s get a quick snapshot of the highlights. This short bullet-list focuses on technical milestones, but the history below, explains the context, social phenomenon and implications.

Short Version:

1965 Hypertext link defined
1970s TCP/IP packet protocol
1983 TCP adopted by Arpanet
1989~91 Http protocol
1991 Public access begins
1995 Netscape Mozilla (1st browser)

— Scroll below Q&A for context and commentary* —

Question: In the 90s, how could we access the internet without WiFi?

Answer: We didn’t need WiFI in the 1990s and we don’t need it now. In both era’s, you can simply attach your PC to the internet with a network cable. If your PC does not have an Ethernet port, you can add a miniature USB-Ethernet adapter. They are inexpensive.

Likewise, before internet service was available to almost every home and business, you could access the internet via telephone modem, or by visiting a library, internet cafe or office that had a leased line for fast access.*

In each case, adoption goes hand in hand with infrastructure build-out, cost reduction and (in the case of WiFi), the desire to move about the home or community more freely.

*A brief history of Public Internet Access

1965: The concept of “hypertext” and clickable “links”. But demonstrations were limited to a single computer or a local network. The first mouse was patented in 1967. But for the next 15 years, few people used a mouse or pointing device.

1970s: The Internet and its predecessor, the Arpanet, was a constellation of networked terminal access tools that connected universities and research labs. Finding material and accessing it required command line jargon that limited its use. You could access the web and most standards were in place—but there was no universal browser that incorporated hypertext links.

1983: Apple introduces the Lisa (predecessor to the Macintosh). It included a mouse, which most people had never used before. Not to be outdone, Microsoft offered an aftermarket Mouse for $195 which came bundled with Word and Notepad.

1991: The public gained access in 1991 after Tim Berners-Lee, posted a summary of the project and the http standard that he pioneered.

1995: Netscape introduces Mozilla (later renamed Netscape browser). It kicked off a gradual migration of data from FTP and Usenet servers to web pages (http protocol) and an explosion in services and subscribers.

Final Impediments to Adoption: Complexity & Connection infrastructure

In-home use still required special equipment (a telephone modem) and applications had to be installed from a CD or multiple floppy discs. These apps modified the operating system by adding a TCP stack and a Windows Socket API. Prior to these things being bundled into new PCs, the process was a daunting. And so, for the next 10 years, many people accessed the internet from Internet cafes, schools or libraries.

1999: The WiFi standard was introduced in 1997. But it had technical limitations that limited its appeal. In 1997, 802.11b, the first widely used and supported WiFi standard, brought the freedom of movement into homes. This occurred at around the same time that many people were moving from a desktop or tower computer to a laptop.

WiFi-b and later g and n helped to propel convenient Internet access from anywhere within a home. Over the next decade, consumers came to expect an available WiFi signal in offices, schools, restaurants, hotels and airports.

2003: Rise of Social Media

Myspace wasn’t the first social media platform. Friendster beat it out by almost a year. But Myspace was the first to go viral and nationwide among many demographics. Along with Facebook—which eclipsed Myspace in subscriber growth—social media platforms turned many infrequent users into constantly-connected consumers.

  • Friendster March 2002
  • MySpace August 2003
  • Facebook February 2004
  • Twitter March 2006


2007: Apple and AT&T introduced the iPhone in the summer. Prior to 2007, flip phones offered web access via a crude browser built into Palm or Symbion, the OS used by Palm Pilot, Nokia, Motorola and others. But the iPhone kicked off the Smart Phone, a new category of must-have consumer gadgets, which lead to ubiquitous, mobile internet access.

1995 ~ 2020

Gradually, the Internet become a mass market phenomenon. But slow connection speeds and the need to suspend telephone calls limited its use. Between 1978 and 1996, telephone modems gradually improved technology from 300 bps to 56,000 Baud (access at ~25 kbps).

After 1996, consumers gradually switched away from using their telephone lines to a dedicated internet service. Homes connect to an ISP (Internet Service Provider) via either existing phone wire (ISDN), TV cables, Fiberoptic or Wireless-to-home.

Today (2019), it is not uncommon to have residential internet access via a Gigabit fiberoptic connection.

The achievement has been compared to the Wright brothers’ 12-second first flight at Kitty Hawk — an early, aspirational glimpse at a revolution to come. By providing exponentially greater calculation power than the machines we use today, quantum computers could one day transform the way we communicate ideas, conceal data and comprehend the universe.

Paris (AFP) — Scientists claimed Wednesday to have achieved a near-mythical state of computing in which a new generation of machine vastly outperforms the world’s fastest super-computer, known as “quantum supremacy”.

A team of experts working on Google’s Sycamore machine said their quantum system had executed a calculation in 200 seconds that would have taken a classic computer 10,000 years to complete.

A rival team at IBM has already expressed scepticism about their claim.

Is Google moving past the rest of the competition.

Quantum computers’ potential and the advantages they promise over classical computers all remain largely theoretical, and hypothetically speaking, it is predicted that quantum computers will be able to solve problems that are beyond the reach of the classical computers we use today. Passing such a threshold will be considered proof of what we call “quantum supremacy.”

A leaked research paper revealed that Google has reached this level of quantum supremacy but the leak was quickly taken down leaving more questions than answers.

So where do we go from here? What does a world with quantum supremacy look like?
