Integration of the Berry curvature on a qubit state manifold by coupling to a quantum meter system
Peng Xu, Shi-Liang Zhu, Klaus Mølmer +1
We present a scheme that allows integration of the Berry curvature and thus determination of the Chern number of a qubit eigenstate manifold. Our proposal continuously couples the…
(Of course) algorithms beat gamers at solving quantum control problems
Klaus Mølmer, Jacob Sherson
Dries Sels and Allan Grønlund have demonstrated numerical algorithms that outperform the players of our Quantum Moves game and they call the conclusions of our article Exploring th…
Subradiant Dimer Excitations of Emitter Chains Coupled to a 1D Waveguide
Yu-Xiang Zhang, Chuan Yu, Klaus Mølmer
This Letter shows that chains of optical or microwave emitters coupled to a 1D waveguide support subradiant states with close pairs of excited emitters, which have longer lifetimes…
Time-Optimal Control of Collisional Gates in Ultracold Atomic Systems
Jesper Hasseriis Mohr Jensen, Jens Jakob Sørensen, Klaus Mølmer +1
We use quantum optimal control to identify fast collision-based two-qubit gates in ultracold atoms. We show that a significant speed up can be achieved by opti…
Revealing the strokes of autonomous quantum heat engines with work and heat fluctuations
Katerina Verteletsky, Klaus Moelmer
We analyze an autonomous thermoelectric engine composed of two superconducting qubits coupled to separate heat baths and connected by a Josephson junction. Work and heat are proces…
Single-shot determination of quantum phases via continuous measurements
Aniket Patra, Lukas F. Buchmann, Felix Motzoi +3
We propose that weak continuous probing may be exploited to determine and define quantum phases of complex many-body systems based on the measurement record alone. We test the resu…
