The multi-terminal Josephson effect
Natalia Pankratova, Hanho Lee, Roman Kuzmin +6
Establishment of phase-coherence and a non-dissipative (super)current between two weakly coupled superconductors, known as the Josephson effect, plays a foundational role in basic…
High Purity Single Photons Entangled with an Atomic Memory
Clayton Crocker, Martin Lichtman, Ksenia Sosnova +3
Trapped atomic ions are an ideal candidate for quantum network nodes, with long-lived identical qubit memories that can be locally entangled through their Coulomb interaction and r…
Large Stark Tuning of InAs/InP Quantum Dots
Shahriar Aghaeimeibodi, Chang-Min Lee, Mustafa Atabey Buyukkaya +2
InAs/InP quantum dots are excellent sources of telecom single-photon emission and are among the most promising candidates for scalable quantum photonic circuits. However, geometric…
Helical Hinge Majoranas in Iron-Based Superconductors

Motivated by recent experiments on FeTeSe, we construct an explicit minimal model of an iron-based superconductor with band inversion at the point and non-topolog…
Training of Quantum Circuits on a Hybrid Quantum Computer
D. Zhu, N. M. Linke, M. Benedetti +10
Generative modeling is a flavor of machine learning with applications ranging from computer vision to chemical design. It is expected to be one of the techniques most suited to tak…
Manifestations of spin-orbit coupling in a cuprate superconductor
Zachary M. Raines, Andrew A. Allocca, Victor M. Galitski
Exciting new work on Bi2212 shows the presence of non-trivial spin-orbit coupling effects as seen in spin resolved ARPES data [Gotlieb et al., Science, 362, 1271-1275 (2018)]. Moti…
Optical response of Luttinger semimetals in the normal and superconducting states
Igor Boettcher
We investigate the optical response properties of three-dimensional Luttinger semimetals with the Fermi energy close to a quadratic band touching point. In particular, in order to…
Advances in Quantum Reinforcement Learning
Vedran Dunjko, Jacob M. Taylor, Hans J. Briegel
In recent times, there has been much interest in quantum enhancements of machine learning, specifically in the context of data mining and analysis. Reinforcement learning, an inter…
Fluctuation-induced torque on a topological insulator out of thermal equilibrium
M. F. Maghrebi, A. V. Gorshkov, J. D. Sau
Topological insulators with the time reversal symmetry broken exhibit strong magnetoelectric and magneto-optic effects. While these effects are well-understood in or near equilibri…

In a recent high-quality experimental work on normal metal--superconducting nanowire junctions arXiv:1807.01940 (2018), strong anisotropic suppression of induced superconductivity…
Quantum repeaters based on two species trapped ions
Siddhartha Santra, Sreraman Muralidharan, Martin Lichtman +3
We examine the viability of quantum repeaters based on two-species trapped ion modules for long distance quantum key distribution. Repeater nodes comprised of ion-trap modules of c…
