Generation of Motional Squeezed States for Neutral Atoms in Optical Tweezers
Vincent Lienhard, Romain Martin, Yuki Torii Chew +3
Optical tweezers are a powerful tool for the precise positioning of a variety of small objects, including single neutral atoms. Once trapped, atoms can be cooled to the motional gr…
Measurement and feed-forward correction of the fast phase noise of lasers
Tom Denecker, Yukii Torii Chew, Oscar Guillemant +4
Lasers are the workhorse of quantum engineering in the atomic-molecular-optic community. However, phase noise of the laser, which can be especially large in popular semiconductor-b…
Atom Camera: Super-resolution scanning microscope of a light pattern with a single ultracold atom
Takafumi Tomita, Yuki Torii Chew, Rene Villela +6
Sub-micrometer scale light patterns play a pivotal role in various fields, including biology, biophysics, and AMO physics. High-resolution, in situ observation of light profiles is…
Generation of 480 nm picosecond pulses for ultrafast excitation of Rydberg atoms
Tirumalasetty Panduranga Mahesh, Takuya Matsubara, Yuki Torii Chew +3
Atoms in Rydberg states are an important building block for emerging quantum technologies. While the excitation to the Rydberg orbitals are typically achieved in more than tens of…
Strong Spin-Motion Coupling in the Ultrafast Dynamics of Rydberg Atoms
Vineet Bharti, Seiji Sugawa, Masaya Kunimi +7
Rydberg atoms in optical lattices and tweezers is now a well established platform for simulating quantum spin systems. However, the role of the atoms' spatial wavefunction has not…
Ultra-precise holographic optical tweezers array
Yuki Torii Chew, Martin Poitrinal, Takafumi Tomita +4
Neutral atoms trapped in microscopic optical tweezers have emerged as a growing platform for quantum science. Achieving homogeneity over the tweezers array is an important technica…
