WebbAtom interferometers have many uses in fundamental physics including measurements of the gravitational constant, the fine-structure constant, the universality of free fall, and have been proposed as a method to detect gravitational waves. [1] They also have applied uses as accelerometers, rotation sensors, and gravity gradiometers. [2] Webb7 nov. 2024 · Here, we develop a Ramsey interferometry with Bloch states in S- and D-band of a triangular optical lattice for the first time. The key to realizing this interferometer in two-dimensionally coupled lattice is that we use the shortcut method to construct π/2 pulse. We observe clear Ramsey fringes and analyze the decoherence mechanism of …

Webb6 dec. 2024 · We discuss quantum variational optimization of Ramsey interferometry with ensembles of N entangled atoms, and its application to atomic clocks based on a Bayesian approach to phase estimation. We identify best input states and generalized measurements within a variational approximation for the corresponding entangling and … Webb16 aug. 2024 · Since Ramsey interferometry is commonly used in quantum metrology, in this work, we will use Ramsey interferometry to validate the quantum states prepared by the optimized pulse trains in section 3. In the stage of state preparation, a pulse train is applied and the Hamiltonian of the system can be expressed as: info rakuten-card.co.jp 迷惑メール
