Dr. David Schmid, Dr. Lídia Del Rio and Hans Busstra explore a metaphysical shift that’s happening in the foundations of physics: the wave function is no longer regarded as something real, but just as a description of what we know about the world. In philosophical terms: the wave function is not ontic, but epistemic. And in more popular terms: the multiverse is science fiction, resting on a too-literal interpretation of a piece of mathematics called the Schrödinger equation.

Here are some notable perspectives attributed to Dr. David Schmid, a quantum foundations researcher at the Perimeter Institute:
🎓 On the nature of the quantum state
-
"The wave function is no longer regarded as something real, but just as a description of what we know about the world. In philosophical terms: the wave function is not ontic, but epistemic."
In a recent discussion with Dr. Lídia Del Rio, Schmid emphasized that the quantum state reflects our knowledge rather than an objective reality (essentiafoundation.org).
🧠 On the epistemic interpretation
-
"The quantum state only exists in our mind."
Together with Del Rio and Hans Busstra, Schmid explores this foundational view in a video titled “Why the quantum state only exists in our mind” (essentiafoundation.org).
🤔 On the implications for the multiverse
-
"The multiverse is science fiction, resting on a too-literal interpretation of a piece of mathematics called the Schrödinger equation."
By taking a less literal (epistemic) stance, Schmid argues that many-worlds interpretations overreach what the wavefunction actually represents (essentiafoundation.org).
🧩 Wrapping it up
Dr. Schmid's contributions focus on clarifying that:
-
The wavefunction isn’t a physical object—it encodes knowledge of a system.
-
This epistemic view challenges realist or many-worlds narratives.
-
He’s actively publishing on noncontextuality and the foundations of quantum theory (perimeterinstitute.ca).
Would you like pointers to his academic papers or a video where he delves into these ideas?

Here are several insightful quotes and perspectives from Dr Lídia del Rio, a leading quantum information theorist based in Zurich:
🎙️ Collaborative Nature of Science
"We need to cut down this culture of the cult of the genius… science is highly collaborative…and it’s not the product of a lone genius and you don’t need to be a genius to enter the field." (insidequantum.org)
She emphasizes that physics thrives on community and teamwork—not the myth of solitary brilliance.
🧠 Mental Health & Personal Growth
Reflecting on her own journey:
"It’s not normal to struggle so much with the things you struggle with. And you should go and see a mental‑health specialist and get diagnosed." (qspace.fqxi.org, insidequantum.buzzsprout.com)
Dr del Rio highlights the importance of mental‑health support in academia, emphasizing self‑care and early diagnosis—she discovered she has ADHD recently and it transformed her self‑understanding.
🎭 Quantum Observers & the ‘Theater’ Analogy
In collaboration with Renato Renner:
They liken quantum physics to a stage where observers actively participate, not just passively watch—tearing down the barrier between audience and performer (insidequantum.buzzsprout.com, qspace.fqxi.org).
This metaphor captures their view that quantum agents are part of the experiment, not external spectators.
🧩 Philosophical & Logical Foundations
On the limits of applying classical logic in quantum settings:
They point out that Fitch’s knowability axioms are incompatible with quantum theory, and classical modal logic breaks down when agents and their knowledge are treated quantum-mechanically (philpapers.org, arxiv.org, arxiv.org).
This underscores her deep work in quantum epistemology and multi-agent logic.
🧪 On Modelling Agents in Quantum Theory
From interviews and thought experiments:
She stresses the complexity of modelling observers as quantum systems themselves, particularly in self-referential setups like Wigner’s friend and Frauchiger–Renner scenarios (lifeboat.com).
Would you like references to her key papers, or perhaps links to some of her talks and panel discussions from 2024–2025?

„The vacuum carrying information“ is the same concept like the Vedic akashic records. All the eastern philosophies talk about quantum mechanics and universal principles. I wonder how long it will take till the first western scientist starts to apply the ancient descriptions on quantum physics. From my point of view we are heading towards a huge paradigm shift and a quantum leap of our consciousness and our understanding of reality itself.
