Abstract: The invention relates to a quantum computing device comprising at least one atom, wherein the at least one atom has a first electronic state, a second electronic state, and a third electronic state, wherein the third electronic state is a Rydberg electronic state, and an optical capture device configured to emit electromagnetic radiation to capture one or more of the at least one atom, wherein the optical capture device is configured to emit the electromagnetic radiation at a capture wavelength, wherein the first electronic state, the second electronic state, and the Rydberg electronic state have a substantially equal AC polarizability for the capture wavelength. The invention further relates to a use of a quantum computing device and a method for quantum computing.

Abstract: The present invention relates to a device (10) for generating optical tweezers comprising a laser beam source (11) for generating a laser beam (12) and at least one acousto-optic deflector (13) for generating an array (15) of partial beams (14) of the laser beam (12), wherein the array (15) comprises rows (15c). The device (10) further comprises a stepped mirror unit (16) comprising at least a first stepped mirror (25) for reducing a row distance (15d) of the partial beams (14) of the array (15), wherein the first stepped mirror (25) comprises mirrors (30), a stepped distance (25a) between adjacent mirrors (30) and a stepped height (25b).
