Quantum state tomography and squeezed state preparation of a mechanical oscillatorMichael R Vanner1, •Igor Pikovski1, Myung S Kim2, Nikolai Kiesel1, Klemens Hammerer3, Caslav Brukner1, Gerard J Milburn4, and Markus Aspelmeyer11University of Vienna, Vienna, Austria — 2Queen's University Belfast, Belfast, United Kingdom — 3Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences, Innsbruck, Austria — 4The University of Queensland, Brisbane, Australia

We propose a short pulsing scheme which allows squeezed state generation of a mechanical oscillator via projective measurements and complete quantum state tomography. Despite initial thermal occupation, we show that squeezing of the mechanical mode can be observed and low entropy states can be prepared.
