«So I am not sympathetic to the current attempt to replace the quantum wave function with something else.»

Not exact matches

The phenomena are described through classical language, but instead of using classical calculus to predict from one phenomenon to the next, we replace the classical calculus with the quantum algorithm — wave functions, matrices, and so on.

We could say that even in quantum mechanics people still use the Cartesian order to specify the wave function, even though it is describing things that do not fit into the Cartesian order.

Recent results have indeed been able to show that probabilistic predictions in quantum mechanicslogically follow, without any additional postulates, from the description of individual quantum systems, with the aid of the wave function, which can be expressed, as we have seen, in a completely non-probabilistic way and the assumption that the objective properties of the system can be obtained by measurements with certainty.

While the probability theorems of this theory allow us accurately to predict the behaviour of a sufficiently large group of identical quantum entities, the wave function of an individual quantum system describes itspofenf / al to produce certain outcomes when appropriate measurements are taken.

The wave functions of quantum theory illustrate this.

For nearly a century, physicists have explained the peculiarities of their quantum properties — such as wave - particle duality and indeterminism — by invoking an entity called the wave function, which exists in a superposition of all possible states at once right up until someone observes it, at which point it is said to «collapse» into a single state.

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?

Symbolised by the Greek letter psi, the wave function gave them a way to apply their much - loved mathematics of waves to the quantum world.

A quantum - style microscope has imaged the hydrogen atom's wave function, the equation that determines its electrons» positions — and in turn the atom's properties.

Measuring the position of a single electron «collapses» the wave function, forcing it to pick a particular position, but that alone is not representative of its normal, quantum presence in the atom.

By altering the quantum - mechanical wave nature or wave functions of the reactants, we are now able to control, to an extent far greater than was previously possible, the final product.

In effect, the shape of the disk is like the wave function of a quantum particle bouncing around in a cavity with walls at the disk's inner and outer edges.

In that limit he found the equation describing the system is the same as Schrödinger's, with the disk itself being described by the analog of the wave function that defines the distribution of possible positions of a quantum particle.

But standard quantum mechanics doesn't fully explain why large objects don't exist in superpositions, or how and why wave functions collapse.

In quantum terminology, the particle's wave function, which characterizes the spreading of the particle, collapses to a single location (SN Online: 5/26/14).

Such information loss would wreck quantum mechanics, which requires that the «wave function» that describes any system — be it the dictionary or the universe — evolve in a predictable way.

Extensions to standard quantum theory can alleviate these conundrums by assuming that wave functions collapse spontaneously, at random intervals.

In quantum systems inside the neuron, Hameroff and Penrose argue that it's each collapse of the wave function that yields a conscious moment.

Traditional quantum mechanics says that a physical system doesn't have definite properties until it's observed — an act known as collapsing a wave function.

The usual perspective of quantum mechanics is that as soon as you measure something, the wave function literally collapses, going from a state that reflects all potential outcomes to a state that reflects only one: the outcome you see at the moment the measurement is done.

In the above study, electrons in the conductor are described by the wave functions of quantum mechanics and the magnetic field is expressed as the U (1) gauge field.

In 1928 English physicist Paul Dirac did that with his equation describing an electron in terms of both its wave function (ψ)-- the quantum probability of its being in a particular place — and its mass times the speed of light squared (mc2), a relativistic interpretation of its energy.

The wave function helps predict the results of quantum experiments with incredible accuracy.

The Amazing Story of Quantum Mechanics By James Kakalios (Gotham) Professor and professed nerd Kakalios explains the quantum world through science fiction characters like Buck Rogers and Dr. Manhattan from Watchmen, who «gained independent control over his quantum mechanical wave function» to teleport and change his size.

Teleportation is a protocol about how to send a quantum state — a wave function — from one place to another.

No appeal to quantum gravity is required to localize the wave functions of composite matter.

In the quantum world, the light follows all possible paths, but when these are superposed, the wave - functions interfere destructively away from the classical path.

Following their 2012 paper, Mayboroda and Filoche looked for ways to extend the landscape function from mechanical vibrations to the quantum world of electron waves.

Their wave functions might become linked in ways that can influence the directions of the particle pairs, akin to the linked behaviours in quantum entanglement.

In another bit of quantum weirdness, most attempts to directly observe wave functions actually destroy them in a process called collapse.

Instead of having the ability to describe where a particle is, quantum theory provides a description of its whereabouts called a wave function.

The creators of quantum mechanics developed a powerful mathematical tool — the wave function — to predict how a fluctuating particle / wave moves through space and time.

Physicists describe quantum reality in an equation they call the wave function, which reflects all the potential ways a system can evolve.

Solving the Schrödinger equation for the many - electron wave function has been a key challenge in quantum chemistry for decades.

The Warsaw physicists used quantum holography to reconstruct wave function of an individual photon.

Researchers hope that in the future they will be able to use a similar method to recreate wave functions of more complex quantum objects, such as certain atoms.

Since the Warsaw physicists were facing a seemingly impossible task, they attempted to tackle the issue differently: rather than using classical interference of electromagnetic waves, they tried to register quantum interference in which the wave functions of photons interact.

Likewise, because of a phenomenon called quantum entanglement, the very atoms of the human eye interact with the particle - wave duality of light just like any other object, and the simple commingling of photons with the atoms of our sense apparatus serve to collapse the wave function through their intercourse.

I'm not sure how I feel about the pipeline — or rather, I have opinions about it all but they go in different directions and, like a quantum cat in Schrodinger's box I'm in several different states at once because my wave function hasn't collapsed — but I can certainly see why activists have chosen it for their «crusade.»

It sought a complementarity between thermodynamics and quantum mechanics by means of star - hermitian operators and the view that it is the instability of a physical system that is responsible for the amplification and collapse of the wave function.

When I was a physicist, back in the days when supercomputers had as much power as a cellphone, those of us who studied orientational forces between molecules of hydrogen or nitrogen used spherical harmonics to represent the behaviors (shperoidal wave functions, actually, since it is a quantum - mechanical problem).
