The World’s First Quantum Chess Tournament Announces a Winner

Perimeter Institute’s Aleksander Kubica won: So what’s quantum chess? It’s a complicated version of regular chess that incorporates the quantum concepts of superposition, entanglement, and interference. “It’s like you’re playing in a multiverse but the different boards [in different universes] are connected to each other,” said Caltech physicist Spiros Michalakis during a livestream of the tournament. “It makes 3D chess from Star Trek look silly.” Jennifer Ouellette, “We have a winner in the world’s first quantum chess tournament” at Ars Technica Okay: Superposition: Elementary particles of our universe are not in one single specific place, they are only in a probable one. Entanglement: What happens to one elementary particle affects any other particle entangled with it, no matter how far…

Could Slowing Quantum Processes Lead To More Useful Computing?

_{“Adiabatic” quantum computing slows down the process, in the hope of achieving more reliable quantum positions} _{News

Programming, Science}

In a recent podcast, “Enrique Blair on quantum computing,” Walter Bradley Center director Robert J. Marks talks with fellow computer engineer Enrique Blair about why quantum mechanics is so strange but important to our future. They discussed the prospects of slowing down quantum computing to make it more useful (adiabatic computing). https://episodes.castos.com/mindmatters/Mind-Matters-110-Enrique-Blair.mp3 The discussion of quantum communication begins at approximately 58:47. The Show Notes and transcript follow. Enrique Blair (pictured): I guess the challenge with entangling massive numbers of quantum systems is that entanglement becomes much more fragile. In quantum communication, you just need pairs of photons to be entangled. One with another, that’s it. Whereas with quantum computing, you need many, many systems to be entangled, and that’s just…

The Final Ambiguous Truth About Schrödinger’s Cat

_{Schrödinger came up with the cat illustration to explain quantum mechanics to interested people who were not physicists} _{News

November 30, 2020

Science}

In last week’s podcast, “Enrique Blair on quantum computing,” Walter Bradley Center director Robert J. Marks talks with fellow computer engineer Enrique Blair about why quantum mechanics is so strange. Inevitably, the discussion turned to what really happened with Schrödinger’s cat, the one who is either dead or alive only if we actually look at it. https://episodes.castos.com/mindmatters/Mind-Matters-110-Enrique-Blair.mp3 [Schrödinger’s cat starts approximately at 21:50.] The Show Notes and transcript follow. Excerpts from the transcript: Robert J. Marks (pictured): We hear a lot in popular culture about Schrödinger’s cat. Now, Erwin Schrödinger (1887–1961) was one of the guys who formulated quantum mechanics. He won a Nobel Prize for it. He was trying to explain quantum mechanics to a layperson and he used…

How Scientists Have Learned To Work With the Quantum World

In last week’s podcast, “Enrique Blair on quantum computing,” Walter Bradley Center director Robert J. Marks talks with fellow computer engineer Enrique Blair about why quantum mechanics is so strange. But scientists have learned to work with QM, despite many questions, like how to work with particles that can be in two different places (quantum superposition): https://episodes.castos.com/mindmatters/Mind-Matters-110-Enrique-Blair.mp3 [Starts at approximately 13:16.] The Show Notes and transcript follow. Excerpts from the transcript: Robert J. Marks: What’s superposition? What’s going on there? Enrique Blair: Quantum superposition is really a mathematical description. We use wave functions to describe these particles. There’s a wave function for the photon going through Slit One and a wave function for the photon going through Slit Two. To…

In this week’s podcast, “Enrique Blair on quantum computing,” Walter Bradley Center director Robert J. Marks talks with fellow computer engineer Enrique Blair about why Quantum mechanics pioneer Niels Bohr said, “If quantum mechanics hasn’t profoundly shocked you, you haven’t understood it yet.” Let’s look at some of the reasons he said that: https://episodes.castos.com/mindmatters/Mind-Matters-110-Enrique-Blair.mp3 The Show Notes and transcript follow. Enrique Blair: It’s really quite different from our daily experience. Quantum mechanics really is a description of the world at the microscopic scale. And it’s really weird, because there are things that initially we thought maybe were particles but then we learned that they have wave-like behaviors. And there are other things that we thought were waves and then we…

A Materialist Gives Up on Determinism

_{Evolutionary biologist Jerry Coyne undercuts his own argument against free will by admitting that quantum phenomena are real} _{Michael Egnor

November 16, 2020

Philosophy of Mind, Science}

Evolutionary biologist Jerry Coyne has denied free will for years. But most recently, he has said something that puts the whole matter in doubt. A bit of background: Free will simply cannot be real if determinism is true, that is, if everything in nature falls like dominoes after the first one is pushed: If nature is truly like that, our acts, like those of the dominoes, are wholly determined by natural history and physical laws that we do not control. Nearly all arguments against free will depend critically on determinism. But there is a central problem with determinism: It is clear from physics that determinism in nature is not true. In 1964, theoretical physicist John Bell (1928–1990) proposed relatively simple…

Will Quantum Mechanics Produce the True Thinking Computer?

_{Quantum computers come with real world problems of their own} _{News

Artificial Intelligence, Philosophy of Mind}

Some hope that quantum mechanics can explain human consciousness. Maybe we are all quantum computers but don’t know it? Maybe quantum computers could think like people? There is an odd relationship between the human mind and quantum mechanics, the science of entities like electrons that are too small to be governed by ordinary physics. Some aspects of consciousness appear to be mediated by such elementary particles. Science writer Philip Ball explains, Nobody understands what consciousness is or how it works. Nobody understands quantum mechanics either. Could that be more than coincidence? Quantum mechanics is the best theory we have for describing the world at the nuts-and-bolts level of atoms and subatomic particles. Perhaps the most renowned of its mysteries is…
