About

Intersection of quantum effects and living systems.

QBI² brings together quantum physicists, chemical biologists, biomedical researchers, and industry expertise to investigate whether and how quantum engineering can advance the life sciences, and quantum phenomena control biological systems.

Our annual workshop anchors on a specific focal topic the community is ready to move forward on, examining where quantum phenomena may be utilized to transform our capabilities to study and control biological systems, and where quantum phenomena may genuinely shape biological function, and where evidence falls short.

The goal is not consensus but clarity: to map what is known, identify what remains contested, and figure out where the real scientific and translational opportunities lie.

QBI² is as much about building community as advancing ideas. We connect researchers across disciplines, sparking collaborations and creating space for the kinds of conversations and ideas that demand an in-depth, focused discussion, and inspire exchange between academia and industry.

For 2026, protein science is the lens. The workshop focuses on protein spin qubits and related spin effects: genetically encoded and chemically targeted spin systems that can be initialized, manipulated, and read out within living systems.

What we aim to do

  • Map what is already known across quantum physics and the life sciences.
  • Identify what remains contested and where the open questions sit.
  • Locate the real scientific and translational opportunities worth pursuing.
  • Build community and spark cross-disciplinary collaborations.
Program

Two days of photoactive protein spins

From fluorescent protein spin qubits to radical-pair systems and the translational opportunities in quantum biology - a focused, single-track program.
