Quantum Co-Design of Inhomogeneous Many-Body Neutrino Fast Flavor Transformation
Researchers developed QCNO, a quantum simulation code to study neutrino flavor evolution in inhomogeneous systems. It maps complex neutrino Hamiltonians to quantum circuits, successfully reproducing many-body effects like entanglement and non-stabilizer structure for N=30. The work connects ideal simulations with hardware noise and estimates the fault-tolerant resources needed for accurate results.
