We are happy to announce that our paper “Tunable coupler to fully decouple and maximally localize superconducting qubits” has been published in Physical Review Applied. In our paper, we derive conditions for tunable couplers to suppress all parasitic interactions, i.e. state delocalization and ZZ-cr...

The Theory of Quantum Technology Group at FAU Erlangen-Nürnberg, lead by professor Michael J. Hartmann invites applications for a postdoc position in quantum algorithms and quantum simulation.The positions will be part of the Bavarian and German programs to develop quantum computers, see e.g. https:...

We are glad to announce that our paper on "Problem Specific Classical Optimization of Hamiltonian Simulation" has been published in Physical Review Research. In our paper, we introduce a variational algorithm for Hamiltonian simulation. As quantum optimization faces fundamental problem when performe...

How can we compute or simulate the time evolution of quantum many-body systems on near-term quantum computers? This is currently one of the most pressing questions in the field. Prof. Michael J. Hartmann gave his inaugural talk on "Quantum Computing on Current Quantum Hardware” on the 5th of July di...

A major bottleneck of current NISQ hardware is low fidelity of 2 qubit gates. A component to improve this is the possibility to completely switch off interactions between qubits. In our pre-print we derive conditions for the coupler to suppress all parasitic interactions, i.e. state delocalization a...

In our latest pre-print, we introduce a variational algorithm for Hamiltonian simulation. As quantum optimization faces fundamental problem when performed on a quantum machine, we studied optimization on a classical computer. As opposed to prior work, the presented algorithm is applicable to any loc...
