Buddhist Theory agrees with Quantum Physics!

Point 1: The fact of dependency of all phenomena and their spatial inseparability:
The arising of all entities is dependent on other entities! This is the core concept
in Buddhism of co-dependent co-arising (Paticca Samuppada)  which may just be an
expression of quantum entanglement of all mental objects, all mental forms of energy.

On the illusion of space and the impossibility of causal separability please enjoy this video:

On the Buddhist doctrine of Dependent Origination (Paticca-Samuppāda):
Cohesive Co-Origination, Dependent_Origination, Collapsible Co-Cessation,
Dependent_Origination, Caused by What, Causes of Emergence, Wise Ontology
Crucial Necessity, Profound_Causality, Past_Cause_Present_Effect, Bound_to_Be
Elemental Analysis, No-Agent but Dependence, Not Yours, The Proximate Cause,
Assured_&_Ascertained_Awakening, Evident_Facts, Dependent_Causation,

Point 2: Observation itself = mind creates/conditions the observed object in each moment!
All entities = forms of energy have TWO complementary (Niels Bohr) characteristics:
1: They are particulate = local = have a definable position in space and time. AND!
2: They are wavelike = non-local = everywhere present = no defined position in space.
Observation = mind causes the wavelike aspects to collapse into particulate existence.
This principle was coined participatory observation by John Archibald Wheeler.

Regarding "Consciousness causes Collapse" please see Radin's 2012 experiments:

Enjoy this Double Slit Experiment. Note the end difference of observation itself!

Consciousness causes the collapse of the probability wave into reality!

Point 3: There is something real apart from and outside of the dimensions of space and time:
Time & space are not conditions in which we live, but modes by which we think... Albert Einstein.
Time & space are not objective things, but mentally imposed orders of things... Leibniz

Enjoy this illustration of how we might be imprisoned in too few or too many dimensions:

Regarding the everywhere presence of consciousness humans are as naive as 2D Flatlanders!

Nibbāna is indeed an unborn and uncreated state out-side of space & time:
Climax of Calm, Final Freedom, The Proximate Cause, Peace, What_is_Nibbana,
Nibbana or non-return, Reaching Peace, The_2_Nibbanas, The_Uncreated,
How_to_Enter, Nibbana_True_Peace, The_Entrance, The_Unborn_State,
The_Signless_Nibbana, Nibbana_Still, Imperturbable_Equanimity,
Doctrine of Nibbana.

Point 4: There is not an external reality  independent of the observing mind:

Phenomena comes into being when an observer intentionally observes it!
 
 Nibbāna is not a place. It is unchanging = without time. Yet it is real! 

As the Buddha Gotama said:
Nibbānam paranam sukham...
Nibbana is the Highest Bliss!
Dhammapada 203/204

The stuff of the world is mind-stuff.
(Eddington, The Nature of the Physical World)

The old dualism of mind and matter... seems likely to disappear ...
through substantial matter resolving itself into a creation and
manifestation of the mind.
(Jeans, The Mysterious Universe)

The only acceptable point of view appears to be the one that recognizes
both sides of reality—the quantitative and the qualitative, the physical
and the psychical—as compatible with each other, and can embrace them
simultaneously. (Pauli, Writings on Physics and Philosophy)

The conception of the objective reality of the elementary particles has
thus evaporated not into the cloud of some obscure new reality concept,
but into the transparent clarity of a mathematics that represents no longer
the behaviour of the particle but rather our knowledge of this behaviour.
(Heisenberg, The Representation of Nature in Contemporary Physics)
