Quantum Synchronization of Perturbed Oscillating Coherences

Kavli Affiliate: Joel E. Moore | First 5 Authors: Yi J. Zhao, Yi J. Zhao, , , | Summary: Synchronization in quantum systems has been recently studied through persistent oscillations of local observables, which stem from undamped modes of the dissipative dynamics. However, the existence of such modes requires fine-tuning the system to satisfy specific […]

Variable-Rate Texture Compression: Real-Time Rendering with JPEG

Kavli Affiliate: Michael Wimmer | First 5 Authors: Elias Kristmann, Elias Kristmann, , , | Summary: Although variable-rate compressed image formats such as JPEG are widely used to efficiently encode images, they have not found their way into real-time rendering due to special requirements such as random access to individual texels. In this paper, we […]

Pareto-optimality of Majoranas in hybrid platforms

Kavli Affiliate: Michael Wimmer | First 5 Authors: Juan Daniel Torres Luna, Juan Daniel Torres Luna, , , | Summary: To observe Majorana bound states, and especially to use them as a qubit, requires careful optimization of competing quality metrics. We systematically compare Majorana quality in proximitized semiconductor nanowires and quantum dot chains. Using multi-objective […]
