Approximate Quantum Fourier Transform in Logarithmic Depth on a Line
Elisa Bäumer, David Sutter, Stefan Woerner
The approximate quantum Fourier transform (AQFT) on qubits can be implemented in logarithmic depth using qubits with all-to-all connectivity, as shown in [Hales, PhD Thesi…

Fluctuating work in coherent quantum systems: proposals and limitations
Elisa Bäumer, Matteo Lostaglio, Martí Perarnau-Llobet +1
One of the most important goals in quantum thermodynamics is to demonstrate advantages of thermodynamic protocols over their classical counterparts. For that, it is necessary to (i…
