Generation of Quantum multi-Phonon states in a mechanical oscillator

Project description

Strong light-matter coupling leads to good vibrations

Light-matter interactions have long intrigued scientists, from focusing sunlight with a mirror to start a fire to 'seeing' inside the human body with beams of electromagnetic energy. We have entered a new realm in which we can investigate such interactions on the level of single photons and individual units of matter such as fundamental particles or atoms. Strong optomechanical coupling, for example, between an optical cavity and a mechanical oscillator, can create non-classical states of particular interest. The EU-funded QuPhon project will investigate the transfer of non-classical light in an optical cavity to a mechanical oscillator. Bridging these two will generate non-classical states of exotic quanta of vibrational energy called phonons with exciting potential applications.

Objective

The main objective of the QuPhon research action is to develop a novel hybrid quantum system between a mechanical oscillator and a superconducting qubit, especially focusing on the generation of nonclassical multi-phonon states in an ultra high-Q mechanical oscillator. The challenging task will be realized by utilizing itinerant microwave photons transferring nonclassical states in a microwave memory cavity to a mechanical oscillator. The architecture of connecting spatially separated quantum modules that function differently enables one to exploit their complementary advantages simultaneously. The achievements will bridge independently-developed quantum technologies between electromechanics and circuit quantum electrodynamics, which will lead to further quantum applications, such as quantum memory and quantum transducer with hardware-efficient quantum error corrections, as well as studies on quantum coherence between two macroscopically distinct states in a massive object.
