Optimal stellar rank approximation of squeezed cat states with photon catalysis
Julian K. Nauth, Nathan Walk, Ananga M. Datta +4
Non-Gaussian quantum states and operations constitute essential resources for achieving quantum computational advantage and enabling quantum error correction in bosonic platforms.…
Strategy optimization for quantum conference key agreement in asymmetric star networks
Janka Memmen, Julia Kunzelmann, Nathan Walk +2
The distribution of entangled states is a core task for quantum networks facilitating quantum communication, and the use of multipartite entangled states comes with its own set of…
Certification of linear optical quantum state preparation
Riko Schadow, Naomi Spier, Stefan N. van den Hoven +6
Certification is important to guarantee the correct functioning of quantum devices. A key certification task is verifying that a device has produced a desired output state. In this…
Below-threshold error reduction in single photons through photon distillation
F. H. B. Somhorst, J. Saied, N. Kannan +14
Photonic quantum computers use the bosonic statistics of photons to construct, through quantum interference, the large entangled states required for measurement-based quantum compu…
Experimental quantum randomness enhanced by a quantum network
Emanuele Polino, Luis Villegas-Aguilar, Davide Poderini +10
The certification of randomness is essential for both fundamental science and information technologies. Unlike traditional random number generators, randomness obtained from nonloc…
