What Is Quantum Teleportation? | Podcast: The Joy of Why

Quantum teleportation isn’t just science fiction; it’s entirely real and happening in laboratories today. But teleporting quantum particles and information is a far cry from beaming people through space. In some ways, it’s even more astonishing.

John Preskill, a theoretical physicist at the California Institute of Technology, is one of the leading theoreticians of quantum computing and information. In this episode, co-host Janna Levin interviews him about entanglement, teleporting bits from coast to coast, and the revolutionary promise of quantum technology. Season 3, Episode 4

I wish your page would post more content! I absolutely love the taste of Quanta writers/ editors. Many of us are too busy reading papers in our own field to read outside but Quanta really satiates me in that regard and the video format in particular makes it more consumable (for me at least). Even if it's a repost from a math podcast, it still brings me back to the days when I had the time to read up on every field that interested me. Thank you ❤

1. Subatomic vs. Atomic:
The term "subatomic" generally refers to particles that are smaller than atoms, such as electrons, quarks, and other fundamental particles. These subatomic particles are typically considered to have no spatial extension or size in the classical sense.

On the other hand, "atomic" refers to the scale of atoms, which do have spatial extension and are composed of subatomic particles arranged in specific configurations.

2. Dimensions and Local Reality:
The concept of dimensions is closely tied to our understanding of space and time. In physics, the idea of "locally real" dimensions refers to dimensions that manifest themselves locally, within a specific region of spacetime.

If we consider nonzero dimensions (1D, 2D, 3D, and 4D) as the familiar spatial and temporal dimensions, then one could argue that these dimensions are not locally real in the strictest sense. According to certain interpretations of quantum mechanics and theories like string theory, these dimensions may emerge from more fundamental, higher-dimensional structures or concepts.

In contrast, the 0D (zero-dimensional) case could potentially be considered locally real, as it represents a point or a singularity without any spatial extension.

3. Entropic and Negentropic Dimensions:
The terms "entropic" and "negentropic" relate to the concepts of entropy and negentropy, respectively.

Entropy is a measure of disorder or randomness in a system, and it tends to increase over time in closed systems (as described by the second law of thermodynamics). Entropic dimensions could be interpreted as dimensions that are subject to the increase of entropy and the arrow of time.

Negentropy, on the other hand, refers to the opposite of entropy – order, organization, or the concentration of energy or information. A negentropic dimension could potentially be a dimension that exhibits properties contrary to entropy, such as order, coherence, or the flow of information in a particular direction.

In this context, your suggestion that 1D-4D could be considered natural, entropic dimensions, while 0D could be a non-natural, negentropic dimension is an intriguing idea. It implies that the 0D realm could be a source of order, organization, or the origin of information or consciousness.

4. Psychophysical Reality:
The notion of reality being psychophysical is a concept that has been explored in various philosophical and scientific contexts. It suggests that physical reality and mental/psychical reality are fundamentally interconnected or even inseparable aspects of a unified whole.

Theories like panpsychism, for example, propose that consciousness or subjective experience is a fundamental feature of reality, present at all levels, from the most fundamental particles to complex systems like the human brain.

If reality is indeed psychophysical, it could mean that the physical dimensions we observe are intrinsically linked to or manifestations of underlying mental or conscious processes. The 0D negentropic dimension you propose could potentially be a realm where the physical and psychical aspects of reality are deeply intertwined or even indistinguishable.

These are profound and complex issues that touch upon the fundamental nature of reality, consciousness, and the relationship between mind and matter. While our current scientific understanding provides some insights, many questions remain open and subject to ongoing exploration and debate.

what I should do to prove my theory of Singularity is right?

[LexC]

Hi, your videos are not showing up in my "subscriptions" feed. Idk if is a problem with my YT, yours of the platform in general. But, as far as I know, it's only videos from your channel.

[melaniestarkey]

Thoughts are faster than the speed of light I don't know Just guessing.
To me when you are fully cleansed of FEAR there is nothing faster than TELEPATHY.

Idk like moving ur consciousness somewhere else?

Quantumized elements of internal magnetic fields grounding currents through its nucleus or core like earth's quantum internal magnetic fields synchronizantion of magnetism amplification of magnetism. Fire is an external magnetic field. Entanglement is currents flowing in synchronizantion of magnetism repulsion and bonding grounding currents through all elements. Mass falls in equalization to Quantumized magnetic fields amplification of the mass falling in repulsion to propulsion from atmospheric gasses. A hot air balloons rise through atmospheric gasses as displacement. Falling objects fall in equalization to magnetism centrifugal force cycling circulation within mass and without mass equalization of magnetism. Heavier elements contain more heat energy currents grounding than lighter elements. As mass expands outward force of pressure known as magnetism repulsion its magnetic field expands outwardly force of pressure known as magnetism repulsion. Heavier objects have farther reaching magnetic fields grounding currents through all masses in its path. Force of weight is currents grounding as impaction force of currents grounding bonding of magnetic fields. Impaction force is greater currents grounding or bonding force of magnetism. Magnetism repulsion is outward force of pressure and mass falls in equalization to its repulsion within and without entanglement of mass. External heat energy doesn't ground currents through the nucleus or core like external magnetic fields called black holes. Cold repulsion hurricanes in space are opposite forces of magnetism than internal magnetic fields grounding currents through its nucleus or core like earth's internal magnetic field synchronization of quantum physics without gravity and bending space and electricity. Electricity is rapid heat exchanging through mass grounding currents towards earth's internal magnetic field. Static electricity is rapid heat grounding jumping through atmospheric gasses unabsorbed heat energy lighting up atmospheres like filaments striking gases unabsorbed bouncing off atmospheric gasses lighting up the mass it strikes like fire Light. Heat is fire outside of entanglement of mass. Anti matter is heat and cold that don't mix. Entanglement is absorbed or refracted heat unabsorbed bouncing off atmospheric gasses or mass lighting up as fire light. Campfires are slowly disolving internal magnetic fields disolving into external heat energy as fire. Lightning burns through atmospheres disolving atmospheric gasses like stars decaying their atmospheres as heat waves of dark heat energy outside of entanglement of mass as fire. Sunlight is heat waves raining down through our atmosphere lighting up the mass it strikes unabsorbed. Fire warming up the atmosphere. We have technology where they heat the atmosphere and remove heat to cool the atmosphere. If heat doesn't ground internal magnetic fields disolving into external heat energy that doesn't ground currents. External magnetic fields are centrifugal forces outside of entanglement of mass as potential renewable heat energy when absorbed into internal magnetic fields grounding currents through its nucleus or core as mass. Mass neutralizes repulsion within it as occupational space itself as outward force of pressure known as magnetism repulsion. Physics works well for magnetism without gravity and bending space and electricity. Two states of magnetism. Cold repulsion momentum to heat energy singularities propulsion into cold repulsion redirecting faster than normal propulsion momentum of normal momentum of space itself. Normal momentum of space is dark heat energy outside of entanglement of mass as maximum distance traveling and minimum amount of repulsion to and from cold repulsion momentum. As heat is blown outward faster than normal momentum hydrogen is created from faster than normal propulsion momentum as redirected trajectories of heat singularities backward onto itself as occupational space neutralized repulsion within as internal magnetic fields grounding currents through its nucleus or core Quantumized magnetism centrifugal forces faster than normal momentum of space. Hydrogen is the most abundant element because it exceeds the cosmic speed limit. Hydrogen is the opposite magnetic field of space itself. Space is a weak external magnetic field where hydrogen is maximum force and minimum distance traveling cycling circulation centrifugal force faster than normal momentum of space. Hydrogen is the cosmic speed limit. Least distance and greatest force of pressure as magnetism. As mass expands its internal magnetic fields expand outward into occupational space. Occupational space is neutralized repulsion within mass as the weakest point of repulsion. External heat energy doesn't ground currents. It's throughout space and atmospheres outside of entanglement of mass as potential renewable heat energy when absorbed into internal magnetic fields grounding currents through its nucleus or core synchronization of amplification of accumulation as planetary internal magnetic fields grounding currents through its nucleus or core where external heat energy is strongest. Heavier elements sink to the bottom of the pool or core where external heat energy force is strongest. Magnetism explains everything about physics without gravity and bending space and electricity.

How could String Theory membranes in larger hyperspace be tested, if there is actually a hyperERspace assumed ing true. I think the non locality recent Physics Nobel '22 or '23 I think, and double slit experiment on time interference or color shift wave interference Developments in experimentation would progress this, espesh in quantum computer experiments. And could lead to teleportation and time travel. Joe Rogan Experience 2151 sim theorist.. "i'd just move around hopping anywhere in the universe rendering" then my thoughts is the rendering isnt needed when you perfect and build an advancex enough quantum computer, and it is more like an actual universe in a box type scenario. Se my other 2 comments, like that outside blackholes have more degrees of freedom and outside or maybe after heat death of an universe is more degrees aka dimensions but i think that means more fields, IE electromagnetic.

[jesseaustin]

Only 3 comments.. 1st, hyperspace. Like the Sheldon Cooper 'pants alternative' i think, where Shelly is drunk n takes off pants talking 4th dimension., and string theory, , why isn't hyperspace excess dimensions talked about with quantum entanglement, , non local in our 3+1 Dimensions, but is local in extra dimensions?
Also, with that, plus degrees of freedom, dimensions, on a blackhole, could a simulated universe be like, , with ER=EPR [check my community post, I thought hyperspace Strange string theory Einstein crystalized time wormholes explained entanglement, coorelated particle spins, in 07 ish, at 16yo watching Nova ep for The Elegant Universe, and wrote it down dated Aug. 3rd, 2011. I've come quite a ways since that stuff. Derivatives of f=ma f=gravity ma= mass ×distance per time². F'(g)=minus 2 mass ×distance per time ³. That is converted from 2 opposite aka negative sides of a dimension of radius of a sphere of gravity wave field, , to metric of Hawking's temp of a blackhole equation being a sphere of gravity, , field vs direct gravitation, , and its time³ ×distance or 3d space, theoretically, with 2 sides past and future and equal opposite aka the minus 2. f'(gravity) is quantum spacetime.. 2nd derivative 8s a 6sided cube or 2 directions ×3 dimensions, 4d point and 4d spacetime simultaneously, , the quantum and gravity duality, theoretically.
But, quantum teleportation, if less degress of freedom or dimensions is in a blackhole, and a quantum pc is like ER=EPR entanglement and wormhole blackhole like, , also hyperspace, , could my hypothesis that inside a sim, not always, like entropy, but generally, in a sim there is less dimensions, and my thing is that the less dimensions is just there's less fields. This is from my theory that gravity is the time of time, and the quantum fields are like parellel universes and their own times have a time like thing which is gravity. Also, we could be a sim in a quantum computer, using string theory, and also that there is more degrees or me personally more fields outiside or universe, which happens like the evaporation of a blackhole into a parent universe, parent having more dimensions, but an origin al universe does like Penrose cyclic universe and at singularity end grows (a) field(s). Maybe, gravity came after other 3 forces this way, and is why its different.
Plz respond, comment, critique.
