*First of all no one even knows if gravitons are really a thing yet. You shouldn't take them for granted.*Please update your data on this subject.

One cannot have quantum gravity without particles, unless a non perturbative observable can be defined in their place

"Absence of particles means absence of Poincare invariance, no standard Fock space.

Particle physics is defined by local perturbative quantum field theory (Poincare groups).

However, Planck level physics is governed by general covariance.

That is why quantum gravity must be defined in terms of loops/knots.

Knot theory is the physical theory that classifies the independent physical states of the quantum field.

Genuine quantum gravitational physics is non perturbative.

General relativity forced in the quantum perturbative framework doesn't work."

Dr. Carlo Rovelli

Are knots quantum states of spacetime?

A graviton is a string with closed loops.

The “reality conditions” are realized by an inner product that is chiral asymmetric, resulting in a chiral asymmetric ordering for the Hamiltonian, and, in an asymmetric description of the left and right handed gravitons.

The first step towards this goal is to recast the Fock description of graviton also in terms of closed loops.

Is made up of the right handed positive frequency of the graviton and the left handed negative frequency of the anti-graviton.

*The particular mechanism is unknown *The quantum physicists at MIT, Princeton, say otherwise: it is known and has been proven.

The deepest connection between gravity and quantum entanglement:

“The universality of the gravitational interaction comes directly from the universality of entanglement- it is not possible to have stress-energy that doesn’t source the gravitational field because it is not possible to have degrees of freedom that don’t contribute to entanglement entropy.”

https://newatlas.com/physics/15-trillion-atoms-quantum-entanglement/The team mixed rubidium metal with nitrogen gas, and heated it up to 176.9 °C (350.3 °F). At that temperature, the metal vaporizes, causing free rubidium atoms to float around the chamber. There they become entangled with each other, and the team can measure that entanglement by shining a laser through the gas.

The researchers observed as many as 15 trillion entangled atoms in the gas, which they say is about 100 times more than any other experiment.

“If we stop the measurement, the entanglement remains for about one millisecond, which means that 1,000 times per second a new batch of 15 trillion atoms is being entangled,” says Jia Kong, first author of the study. “And you must think that 1 ms is a very long time for the atoms, long enough for about 50 random collisions to occur. This clearly shows that the entanglement is not destroyed by these random events. This is maybe the most surprising result of the work.”

The tangled web that is gravity

He found that what emerged was a wormhole connecting the two entangled quarks, implying that the creation of quarks simultaneously creates a wormhole. More fundamentally, he says, gravity itself may be a result of entanglement. What’s more, the universe’s geometry as described by classical gravity may be a consequence of entanglement—pairs of particles strung together by tunneling wormholes.
