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…
Realizing the Nishimori transition across the error threshold for constant-depth quantum circuits
Edward H. Chen, Guo-Yi Zhu, Ruben Verresen +9
Preparing quantum states across many qubits is necessary to unlock the full potential of quantum computers. However, a key challenge is to realize efficient preparation protocols w…
Efficient Long-Range Entanglement using Dynamic Circuits
Elisa Bäumer, Vinay Tripathi, Derek S. Wang +5
Quantum simulation traditionally relies on unitary dynamics, inherently imposing efficiency constraints on the generation of intricate entangled states. In principle, these limitat…
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…
