We demonstrate the coherent control of spin in quantum wells with phase-locked pairs of perpendicularly polarised 100 fs pulses. These pulses induce strong interference in the electron spin polarisation, which shows up in Faraday rotation. The interference oscillations show quantum beating which differs strongly from the case of pulses with parallel polarisation.
