Накратко на български

Левитиращи наночастици се свързват със свръхпроводящи кубити, за да се контролират техните квантови състояния чрез електричество. Това помага да се провери дали принципите на квантовата физика важат и за обекти с по-голяма маса и сложност.

Interfacing Levitated Optomechanics with Superconducting Qubits

The universal validity of the quantum superposition principle is an open fundamental question with far reaching implications for science and technology. Testing and exploiting quantum physics with objects of ever-increasing mass and complexity requires extremely low motional temperatures and superior environmental isolation to avoid decoherence. One of the most promising platforms for the next generation of quantum superposition tests is provided by levitating nanoscale dielectric particles in ultra-high vacuum and controlling their motion with lasers. However, such levitated optomechanical systems are limited by photon scattering decoherence due to the optical trap. The project ELOTEQ developed novel schemes to perform trapped quantum superposition tests in an all-electrical setup, coherently interfacing a charged nanoparticle with superconducting qubits, via which the rotational and translational quantum state can be controlled, interfered, and monitored.

Цел на проекта

The aim of this project is to establish how the quantum state of an aspherical nanoparticle can be coherently interfaced with a superconducting circuit. Its main efforts can be summarized by two goals: (i) We will develop the theoretical tools required to manipulate the ro-translational quantum state of a levitated nanoparticle possessing a monopole and higher multipole moments by connecting it to a superconducting qubit. (ii) We will investigate how entanglement between the nanoparticle and the circuit can be exploited for earth-based macroscopic interference experiments and for coherence-enhanced force and torque sensing. Networking levitated nanoscale objects with quantized electrical circuits and qubits combines the high Q-factors and isolation of the former with the scalability and control of the latter. This project will point the way towards new fundamental tests of quantum physics and towards quantum technology.
