Loss-aware pulse sequence optimization for generating photonic Fock states
Benjamin Stodd, Priyanshu Tiwari, René Sondenheimer +2
We investigate the preparation of frequency-tunable photonic Fock states in a hybrid cavity system consisting of a nonlinear medium and a two-level system. Employing a gradient-bas…
Entanglement and photoelectron holography in dissociative photoionization: molecular quantum eraser
Sebastian Hell, Paul Winter, Martin Gärttner +6
In a double-slit experiment with a bipartite system, the visibility of interference fringes depends on the availability of which-way information. Here, we report a Bell-like state…
Parafermionic Truncated Wigner Approximation
Javad Vahedi, Martin Garttner
We introduce the parafermionic truncated Wigner approximation (TWA), a semiclassical phase-space framework for simulating the nonequilibrium dynamics of lattice systems with fra…
Learning to detect optical nonclassicality
Martina Jung, Suchitra Krishnaswamy, Timon Schapeler +4
Nonclassicality, defined in the quantum optical sense, serves as a resource for photon-based quantum technologies. Therefore, certifying the nonclassicality of a quantum state is c…
Observable nonclassicality witnesses for multiplexed detection systems
Suchitra Krishnaswamy, Martina Jung, Laura Ares +2
We address the problem of constructing witnesses for nonclassical light that are applicable in state-of-the-art photon-counting devices. The key ingredient for the criteria we deri…
Revealing entanglement through local features of phase-space distributions
Elena Callus, Martin Gärttner, Tobias Haas
We formulate an infinite hierarchy of continuous-variable separability criteria in terms of quasiprobability distributions and their derivatives evaluated at individual points in p…
Limitations for adaptive quantum state tomography in the presence of detector noise
Adrian Skasberg Aasen, Martin Gärttner
Assumption-free reconstruction of quantum states from measurements is essential for benchmarking and certifying quantum devices, but it remains difficult due to the extensive measu…
