"Polarized hole spins obtained by sub-picosecond electron scavenging, to surface-anchored molecular acceptors, following circularly-polarized femtosecond pulse excitation... transverse magnetic field induces coherent Larmor precession of hole spins... off-resonance femtosecond pulse coherently rotates... enabled by strong light-matter interaction of perovskite QDs... full quantum-state control of single-hole spins at room temperature... scalable and sustainable future of spin-based quantum information processing"
