Sentences with phrase «wave function real»

Is the uncertainty that comes with the quantum wave function real or a mathematical quirk?

Not exact matches

But if the wave function is not real, what is?

«You can't think of the wave function as a real thing,» says Howard Wiseman of Griffith University in Queensland, Australia.

Pusey, Barrett and Rudolph's theorem, known as PBR, uses a sophisticated mathematical argument to show that any interpretation of quantum mechanics that doesn't treat the wave function as a real object invariably leads to results that contradict quantum theory itself.

Back to the Beginning If QBism is right, if the wave function isn't real and quantum theory doesn't give us a direct description of reality, it leaves unanswered the most basic of all questions: What then is the quantum world actually like?

If they're right and the wave function is real, interpretations like Everett's Many Worlds, which take the reality of the wave function as a given, could start to seem more plausible.

If the wave function isn't actually real, what creates those light and dark bands?

Valentini also feels encouraged by the PBR theorem because it lends support to a central tenet of pilot wave theory: The wave function is real.

For nearly a century physicists have argued about whether the wave function is a real part of the world or just a mathematical tool.

Previous work that claimed to propose a way to test whether the wave function is real made a splash in the physics community, but turned out to be based on improper assumptions, and no one ever ran the experiment.

Alternatively, if the wave function is not real, then there is no fuzziness and the photon is in a single polarisation state all along.

Erwin Schrödinger argued in 1935 that treating the wave function as a real thing leads to the perplexing situation where a cat in a box can be both dead and alive, until someone opens the box and observes it.

If the wave function is real, then a single experiment should not be able to determine its polarisation — it can have both until you take more measurements.

In a complicated setup that involved pairs of photons and hundreds of very accurate measurements, the team showed that the wave function must be real: not enough information could be gained about the polarisation of the photons to imply they were in particular states before measurement.

Visualising a wave function as a real thing is fine for a single particle, but things rapidly get more tricky.

The core essence of «trust» — created today with government guarantees, physical vaults, behemoth balance sheets to make institutions seemingly «too big to fail», and layer upon layer of regulatory framework enforced by «zillions» (yes I know its not a real number and not an accurate one, but there's no way for me to count the bodies spending time making banks function) of people leading very exciting lives holding a gigantic ball of water in the air — is likely on the front edge of a very big wave of foundational change.
