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.…
Improved bounds for connection probabilities in random loop models
Volker Betz, Andreas Klippel, Julian Nauth
We revisit and extend results by Ueltschi [19] on the application of reflection positivity to loop models with . By exploiting additional flexibility in t…
Dicke-state preparation through global transverse control of Ising-coupled qubits
Vladimir M. Stojanovic, Julian K. Nauth
We consider the problem of engineering the two-excitation Dicke state in a three-qubit system with all-to-all Ising-type qubit-qubit interaction, which is also…
Spectral features of polaronic excitations in a superconducting analog simulator
Julian K. Nauth, Vladimir M. Stojanovic
We investigate spectral properties of polaronic excitations within the framework of an analog quantum simulator based on inductively coupled superconducting transmon qubits and mic…
Full time-dependent counting statistics of highly entangled biphoton states
Julian K. Nauth
Highly entangled biphoton states, generated by spontaneous parametric processes, find wide applications in many experimental realizations. There is an increasing demand for accurat…
Interconversion of and Greenberger-Horne-Zeilinger states for Ising-coupled qubits with transverse global control
Vladimir M. Stojanovic, Julian K. Nauth
Interconversions of and Greenberger-Horne-Zeilinger states in various physical systems are lately attracting considerable attention. We address this problem in the fairly gener…
Quantum-brachistochrone approach to the conversion from to Greenberger-Horne-Zeilinger states for Rydberg-atom qubits
Julian K. Nauth, Vladimir M. Stojanovic
Using the quantum-brachistochrone formalism, we address the problem of finding the fastest possible (time-optimal) deterministic conversion between and Greenberger-Horne-Zeilin…
