Local media reports quoted Wang as saying that artificial intelligence, 6G, quantum technology, driverless vehicles, intelligent networks and other “frontier areas” would be the focus of Shenzhen’s investment plans, while the value of its digital economy would account for more than 31 per cent of GDP by 2025.
Money will be used to support innovation in core technologies, city’s Communist Party chief Wang Weizhong says.
A team of Chinese physicists are making some serious progress in the field of quantum mechanics. Recently, this team has measured the speed of quantum entanglement – more affectionately known as “spooky action at a distance”, as Einstein called it.
To summarize quantum entanglement, two or more particles are entangled, which means they share the same wave form. The more technical definition is: “Quantum entanglement occurs when particles such as photons, electrons, molecules as large as buckyballs, and even small diamonds interact physically and then become separated; the type of interaction is such that each resulting member of a pair is properly described by the same quantum mechanical description (state), which is indefinite in terms of important factors such as position, momentum, spin, polarization, etc.”
When most people describe this interesting process, they’ll describe the information transfer as ‘instantaneous’ or ‘near-instantaneous’. Several research teams have attempted to measure the actual speed seen in the transfer of information in entangled systems, but have failed in one way or another, usually resulting from flawed methodology dealing in quantum nonlocality.
Quantum entanglement is the binding together of two particles or objects, even though they may be far apart – their respective properties are linked in a way that’s not possible under the rules of classical physics.
It’s a weird phenomenon that Einstein described as “spooky action at a distance”, but its weirdness is what makes it so fascinating to scientists. In new research, quantum entanglement has been directly observed and recorded at the macroscopic scale – a scale much bigger than the subatomic particles normally associated with entanglement.
The dimensions involved are still very small from our perspective – these experiments involved two tiny aluminum drums one-fifth the width of a human hair – but in the realm of quantum physics they’re absolutely huge.
Forty years ago, IBM researcher Charlie Bennett helped usher in the study of quantum mechanics’ impact on computing. IBM is still at it—and so is Bennett.
Although nothing in the laws of quantum physics limits such quantum weirdness to subatomic particles, the theory predicts that at much larger scales — say, the size of a cat — quantum effects should be so vanishingly small as to be unobservable in practice. Physicists have long debated whether this is just a limitation of our senses and instruments, or whether macroscopic objects are governed by their own set of laws that is fundamentally different from quantum mechanics. To explore this question, researchers have been pushing to observe quantum effects at ever larger scales. “One point of our research is, is there quantum in the classical world?” says Mika Sillanpää, a physicist at Aalto University in Finland.
Quantum drums
In an experiment at the US National Institute of Standards and Technology in Boulder, Colorado, physicist Shlomi Kotler and his collaborators built a pair of vibrating aluminium membranes akin to two tiny drums, each around 10 micrometres long.
Our physical space-time reality isn’t really “physical” at all, its apparent solidity of objects, as well as any other associated property such as time, is an illusion. As a renowned physicist Niels Bohr once said: “Everything we call real is made of things that cannot be regarded as real.” But what’s not an illusion is your subjective experience, i.e., your consciousness; that’s the only “real” thing, according to proponents of Experiential Realism. It refers to interacting entangled conscious agents at various ontological levels, giving rise to conscious experience all the way down, and I’d argue all the way up, seemingly ad infinitum. It’s a “matryoshka” of embedded realities: conscious minds within larger minds.
#ExperientialRealism
So, why Experiential Realism? From the bigger picture perspective, we are here for experience necessary for evolution of our conscious minds. Our limitations, such as our ego, belief traps, political correctness, our very human condition define who we are, but the realization that we largely impose those limitations on ourselves gives us more evolvability and impetus to overcome these self-imposed limits to move towards higher goals and state of being.
We are what we’ve experienced — the sum of our experiences define who we are. In this sense, as free will agents, we are co-creators within this experiential matrix. Non-duality is the essence of Experiential Realism — experience and experiencer are one. How can you possibly separate your own existence from the world, the observer from the observed? Today, philosophers and scientists argue that information is fundamental but consciousness is required to assign meaning to it. That makes consciousness (our experience in a broader sense) the most fundamental, irreducible ground of existence itself, while some philosophers suggest consciousness is all that is.
I believe that schizophrenia although an illness could be a quantum sense in the quantum realm essentially feeling different dimensions which still remain unknown. The minds developed by the military in different projects like the stranger things series is an example of such a wild reality we live in and how interesting dimensions beyond ours touch our reality.
To the average person, most quantum theories sound strange, while others seem downright bizarre. There are many diverse theories that try to explain the intricacies of quantum systems and how our interactions affect them. And, not surprisingly, each approach is supported by its group of well-qualified and well-respected scientists. Here, we’ll take a look at the two most popular quantum interpretations.
Does it seem reasonable that you can alter a quantum system just by looking at it? What about creating multiple universes by merely making a decision? Or what if your mind split because you measured a quantum system?
You might be surprised that all or some of these things might routinely happen millions of times every day without you even realizing it.
Physics has long looked to harmony to explain the beauty of the Universe. But what if dissonance yields better insights?
Quantum physics is weird and counterintuitive. For this reason, the word ‘quantum’ has become shorthand for anything powerful or mystical, whether or not it has anything whatsoever to do with quantum mechanics. As a quantum physicist, I’ve developed a reflexive eyeroll upon hearing the word applied to anything outside of physics. It’s used to describe homeopathy, dishwasher detergents and deodorant.
If I hadn’t first heard of Quantum Music from a well-respected physicist, I would have scoffed the same way I did at the other ridiculous uses of the word. But coming from Klaus Mølmer it was intriguing. In the Quantum Music project, physicists and musicians worked together to unite ‘the mysterious worlds of quantum physics and music for the first time’. They developed a device that attaches to each key of a piano so that, when the pianist plays, the information is piped to a computer and synthesiser, which plays ‘quantum’ tones in addition to the familiar reverberations in the piano.
Researchers have discovered the most precise way to control individual ions using holographic optical engineering technology.
The new technology uses the first known holographic optical engineering device to control trapped ion qubits. This technology promises to help create more precise controls of qubits that will aid the development of quantum industry-specific hardware to further new quantum simulation experiments and potentially quantum error correction processes for trapped ion qubits.
“Our algorithm calculates the hologram’s profile and removes any aberrations from the light, which lets us develop a highly precise technique for programming ions,” says lead author Chung-You Shih, a Ph.D. student at the University of Waterloo’s Institute for Quantum Computing (IQC).
In a feat worthy of a laboratory conceived by J.K. Rowling, MIT researchers and colleagues have turned a “magic” material composed of atomically thin layers of carbon into three useful electronic devices. Normally, such devices, all key to the quantum electronics industry, are created using a variety of materials that require multiple fabrication steps. The MIT approach automatically solves a variety of problems associated with those more complicated processes.
As a result, the work could usher in a new generation of quantum electronic devices for applications including quantum computing. Further, the devices can be superconducting, or conduct electricity without resistance. They do so, however, through an unconventional mechanism that, with further study, could give new insights into the physics of superconductivity. The researchers report their results in the May 3, 2021 issue of Nature Nanotechnology.
“In this work we have demonstrated that magic angle graphene is the most versatile of all superconducting materials, allowing us to realize in a single system a multitude of quantum electronic devices. Using this advanced platform, we have been able to explore for the first time novel superconducting physics that only appears in two dimensions,” says Pablo Jarillo-Herrero, the Cecil and Ida Green Professor of Physics at MIT and leader of the work. Jarillo-Herrero is also affiliated with MIT’s Materials Research Laboratory.
