Publication number: 20240304433Abstract: A method is presented for generating an ion beam. The method includes: positioning atoms in a cavity of an optical resonator that defines an optical dipole trap; exciting the atoms while the atoms are trapped in the optical dipole trap using two or more laser beams, thereby forming ions; and driving the ions along an output axis towards a target by applying an electric field to the ions. In one aspect, the ion density of the ion source is regulated, for example using feedback control. Changing the ion density may be achieved, for example by inputting the atomic excitation spectrum into a feedback loop and controlling the power of the two or more laser beams using feedback from the feedback loop.Type: ApplicationFiled: March 8, 2024Publication date: September 12, 2024Applicants: THE REGENTS OF THE UNIVERSITY OF MICHIGAN, Rydberg Technologies Inc.Inventors: David ANDERSON, Alisher DUSPAYEV, Georg RAITHEL

Patent number: 12000877Abstract: A method for atom-based closed-loop control includes exciting atoms of a gas into one or more Rydberg states, applying one or more signal processing functions to the one or more Rydberg states, and regulating a characteristic of the applied one or more signal processing functions based on, at least in part, a response of the one or more Rydberg states to the one or more signal processing functions. A system for internal quantum-state-space interferometry includes an atomic receiver, an interferometric pathway, and a detector. The interferometer includes an atomic vapor with first atomic states and second atomic states. The interferometric pathway from RF phases between the first and second atomic states is closed by a quantum-state-space. The detector is configured to detect a readout of an interferometric signal. Embodiments include atom-based automatic level control, baseband processors, phase-locked loops, voltage transducers, raster RF imagers and waveform analyzers.Type: GrantFiled: February 23, 2023Date of Patent: June 4, 2024Assignee: Rydberg Technologies Inc.Inventors: David A.

Patent number: 11774482Abstract: Methods and apparatus for sensing or measuring an electromagnetic field. The method entails excitation into a distribution of Rydberg states of atoms of a gas occupying a test volume coextensive with the electromagnetic field. Transmission along a path traversing the test volume of at least one probe beam of electromagnetic radiation is measured at one or more frequencies overlapping a spectral feature, and a physical characteristic of the electromagnetic field is derived on the basis of variation of the spectral feature. In various embodiments, the electromagnetic field may be place in interferometric relation with another electromagnetic field. Time-varying electric field amplitude, frequency, phase and noise spectral distribution may be measured, and thus AM and FM modulated fields, as well as magnetic fields of about 1 Tesla. The apparatus for measuring the electromagnetic field may be unilaterally coupled to a probe field and detector or array of detectors.Type: GrantFiled: June 13, 2022Date of Patent: October 3, 2023Assignee: Rydberg Technologies Inc.Inventors: David A.
