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…
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…
A fiber Fabry-Perot cavity based spectroscopic gas sensor
Carlos Saavedra, Deepak Pandey, Wolfgang Alt +2
Optical spectroscopic sensors are powerful tools for analysing gas mixtures in industrial and scientific applications. Whilst highly sensitive spectrometers tend to have a large fo…
Raman Imaging of Atoms Inside a High-bandwidth Cavity
Eduardo Uruñuela, Maximilian Ammenwerth, Pooja Malik +4
High-bandwidth, fiber-based optical cavities are a promising building block for future quantum networks. They are used to resonantly couple stationary qubits such as single or mult…
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…
Observing crossover between quantum speed limits
Gal Ness, Manolo R. Lam, Wolfgang Alt +3
Quantum mechanics sets fundamental limits on how fast quantum states can be transformed in time. Two well-known quantum speed limits are the Mandelstam-Tamm and the Margolus-Leviti…
