Three-dimensional imaging of single atoms in an optical lattice via helical point-spread-function engineering

Tangi Legrand, Falk-Richard Winkelmann, Wolfgang Alt +3

We demonstrate a method for determining the three-dimensional location of single atoms in a quantum gas microscopy system using a phase-only spatial light modulator to modify the p…

Boson sampling with ultracold atoms in a programmable optical lattice

Carsten Robens, Iñigo Arrazola, Wolfgang Alt +4

Sampling from a quantum distribution can be exponentially hard for classical computers and yet could be performed efficiently by a noisy intermediate-scale quantum device. A prime…

Quantum Speed Limit for States with a Bounded Energy Spectrum

Gal Ness, Andrea Alberti, Yoav Sagi

Quantum speed limits set the maximal pace of state evolution. Two well-known limits exist for a unitary time-independent Hamiltonian: the Mandelstam-Tamm and Margolus-Levitin bound…

Direct measurement of the Wigner function of atoms in an optical trap

Falk-Richard G. Winkelmann, Carrie A. Weidner, Gautam Ramola +3

We present a scheme that uses Ramsey interferometry to directly probe the Wigner function of a neutral atom confined in an optical trap. The proposed scheme relies on the well-esta…

Ramsey imaging of optical traps

Gautam Ramola, Richard Winkelmann, Karthik Chandrashekara +4

Mapping the potential landscape with high spatial resolution is crucial for quantum technologies based on ultracold atoms. Yet, imaging optical dipole traps is challenging because…

Non-equilibrium plasma generation via nano-second multi-mode laser pulses

Andrea Alberti, Alessandro Munafó, Munetake Nishihara +3

A non-equilibrium model for laser-induced plasmas is used to describe how nano-second temporal mode-beating affects plasma kernel formation and growth in quiescent air. The chemica…
