The preparation of mechanical quantum superposition states remains outstanding due to weak coupling and thermal decoherence. An international team of researchers (Australia, UK) present a novel optomechanical scheme that significantly relaxes these requirements allowing the preparation of quantum superposition states of motion of a mechanical resonator by exploiting the nonlinearity of multi-photon quantum measurements. The method can generate non-classical mechanical states without the need for strong single-photon coupling, is resilient against optical loss, and offers more favourable scaling against initial mechanical thermal occupation than existing schemes. It offers potential for the development of powerful new quantum-enhanced technologies, such as ultra-precise sensors, and new types of transducers… read more. Open Access TECHNICAL ARTICLE
