Project: Investigating the deep structural connections between trapped-ion quantum computing platforms and the Posner molecule (Ca₉(PO₄)₆) hypothesis for biological quantum cognition.
Initiated: 2026-05-26
Trapped-ion quantum computers and Posner molecules share a fundamental substrate — controlled nuclear/electronic spin states in calcium-containing systems — yet operate at opposite extremes of the quantum engineering spectrum: one in ultra-high vacuum with electromagnetic precision, the other in warm, wet biological environments. Understanding the connection between these two domains may reveal:
- Whether trapped-ion quantum simulators can model Posner molecule spin dynamics
- How insights from ion trap coherence engineering can inform biological quantum hypotheses
- Whether the calcium ion's nuclear spin physics, extensively characterized in ion traps, constrains or supports the Posner molecule model
- What does trapped-ion QC tell us about calcium nuclear spin coherence that applies to Posner molecules?
- Can trapped-ion quantum simulators model the ³¹P nuclear spin dynamics of Posner molecules?
- How does the "spin-free" calcium environment (⁴⁰Ca, I=0) in Posner molecules compare to the engineered vacuum of ion traps?
- What are the decoherence timescales in each system and what do they imply?
