Lay Summary (English)

Lay summary

Micro- and nano-mechanical oscillators are an established technology in classical applications; they can be used to probe nano-scale phenomena (AFM) and are integral part of RF filters and timekeeping.  It has been a longstanding challenge to establish nanomechanical oscillators as a quantum technology, i.e. process their signals in a manner where quantum mechanics becomes relevant and where thermal motion is frozen out. Over the past years mechanical oscillators have entered this quantum regime and are progressing towards being a third quantum technology, after ions, atoms and molecules and in a second wave superconducting circuits. Mechanical oscillators have in this context unique properties; they can be micro- and nanofabricated and coupled to other quantum systems, serving as intermediary. Their low dissipation is interesting from a point of view of quantum storage.The quantum regime of mechanics has been reached due to the rapid developments of cavity optomechanical coupling that allows state initialization, measurement and coherent coupling to mechanical oscillators.  My laboratory has been in this field from its inception and demonstrated optomechanically induced transparency (optomechanical EIT), measurements of mechanical motion with an imprecision at the standard quantum limit (i.e. a resolution at the level of the zero point motion of the mechanical oscillator) and moreover developed a theoretical understanding of the quantum limits of back-action cooling.  Moreover, using Helium-3 buffer gas cooling we have been able to achieve quantum coherent coupling between light and matter and cooling to > 37% ground state probability of a micromechanical oscillator. 

Within this proposal, we seek to directly build on these novel techniques and the ability to prepare mechanical systems in the quantum regime, and explore the quantum regime of mechanical systems in a variety of ways which are brought by these advances. The aims of our research are in particular to explore the time domain control of the optomechanical interaction and achieve the regime where Quantum Backaction becomes the dominant force force - prerequisite for optomechanical squeezing. Moreover, we will explore the coupling of naturally occuring TLS to mechanical structures - which give rise to non-Ohmic dissipation and direct phonon absorption - and explore accurate thermometry methods for mechanical structures.

Abstract

Micro- and nano-mechanical oscillators are an established technology in classical applications; they can be used to probe nano-scale phenomena (AFM) and are integral part of RF filters and timekeeping. It has been a longstanding challenge to establish nanomechanical oscillators as a quantum technology, i.e. process their signals in a manner where quantum mechanics becomes relevant and where thermal motion is frozen out. Over the past 2 years mechanical oscillators have entered this quantum regime and are progressing towards being a third quantum technology, after ions, atoms and molecules and in a second wave superconducting circuits. Mechanical oscillators have in this context unique properties; they can be micro- and nanofabricated and coupled to other quantum systems, serving as intermediary. Their low dissipation is interesting from a point of view of quantum storage. Finally, mechanical systems in the quantum regime may even test the laws quantum mechanics itself on a novel mass and size scale. The quantum regime of mechanics has been reached due to the rapid developments of cavity optomechanical Physics and novel optomechanical structures. This coupling, first investigated within the context of gravitational wave detection by Braginsky in the 1970, enables a method with which mechanical oscillator can be cooled to the quantum ground state and their motion measurement with a sensitivity at the level of the zero point motion. Moreover, this mutual coupling moreover gives rise to an effective Hamiltonian that enables diverse quantum optical tasks such as state swapping. My laboratory has been in this field from its inception and been at the forefront of several of these developments. My research group demonstrated many foundational experiments in this field, including the first demonstration of mechanical Doppler and sideband cooling, optomechanically induced transparency (optomechanical EIT), measurements of mechanical motion with an imprecision at the standard quantum limit (i.e. a resolution at the level of the zero point motion of the mechanical oscillator) and moreover developed a theoretical understanding of the quantum limits of back-action cooling. Moreover, over the timeframe of several years my group was able to adapt the taper fiber coupling method with a Helium-3 buffer gas cooling cryostat, leading to fiber taper coupling at the lowest temperatures ever (<600 mK). In addition the experiments required to realize quantum limited measurements and to avoid any classical noise, such as laser phase noise or fiber noise. The results have culminated with the demonstration of quantum coherent coupling between light and matter and cooling to ca. 40% ground state probability of a micromechanical oscillator. Within this proposal, we seek to directly build on these novel techniques and the ability to prepare mechanical systems in the quantum regime, and explore the quantum regime of mechanical systems in a variety of ways which are brought by these advances. First, we aim at demonstrating back-action evading measurements on cooled micromechanical oscillators. Using an optical field placed on both upper and lower sideband of a cooled (600 mK) oscillator, it is possible realize for the first time in the optical domain a QND measurement of a single quadrature of a mechanical oscillator and approach with optical means the Heisenberg uncertainty product in an unprecedented manner. Second, we will investigate using higher frequency silica oscillators at these temperatures the dissipation caused by two level structural defect states (TLS) and seek to observe the coherent interaction with ultra small mode volume mechanical resonators.Third, we aim at extending the cavity optomechanical transduction to mechanical oscillators of much higher frequency, by realizing novel multiple cavity mode transducers. Towards this end we plan to continue the joint project with the Walter Meissner Institute of Low Temperature Physics in Munich. In a joint collaboration we have demonstrated a circuit nano-optomechanical platform and used this to demonstrate the slowing of microwaves as well as injection locking of nano-mechanical motion. We seek to use this platform to demonstrate a dual cavity mode transducer, which we proposed in the past theoretically and which enables to achieve high readout sensitivity even for high frequency oscillators.Our experiments aim at exploring further the measurement concepts and utilize the fact that mechanical oscillators can be prepared in the quantum ground state with high probability. It seeks to continue to contribute to the frontiers of the new and emerging field of cavity quantum optomechanics.
