Kavli Affiliate: Michael Wimmer | First 5 Authors: Chun-Xiao Liu, Guanzhong Wang, Tom Dvir, Michael Wimmer, | Summary: Two spatially separated quantum dots connected by a common superconductor has been studied extensively for Cooper pair splitting, and is predicted to be the building block of an emulated Kitaev chain. The effective couplings between quantum dots […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: Chun-Xiao Liu, Guanzhong Wang, Tom Dvir, Michael Wimmer, | Summary: Semiconductor quantum dots have proven to be a useful platform for quantum simulation in the solid state. However, implementing a superconducting coupling between quantum dots mediated by a Cooper pair has so far suffered from limited tunability […]

Kavli Affiliate: Menno Veldhorst | First 5 Authors: Stephan G. J. Philips, Mateusz T. Mądzik, Sergey V. Amitonov, Sander L. de Snoo, Maximilian Russ | Summary: Future quantum computers capable of solving relevant problems will require a large number of qubits that can be operated reliably. However, the requirements of having a large qubit count […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: Adam Celarek, Pedro Hermosilla, Bernhard Kerbl, Timo Ropinski, Michael Wimmer | Summary: This paper proposes a novel method for deep learning based on the analytical convolution of multidimensional Gaussian mixtures. In contrast to tensors, these do not suffer from the curse of dimensionality and allow for a […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: Chun-Xiao Liu, Michael Wimmer, , , | Summary: We study the electronic properties of a planar semiconductor-superconductor heterostructure, in which a thin ferromagnetic insulator layer lies in between and acts as a spin filtering barrier. We find that in such a system one can simultaneously enhance the […]
Kavli Affiliate: Simon Groblacher | First 5 Authors: Jingkun Guo, Simon Gröblacher, , , | Summary: The rapid development of high-Q macroscopic mechanical resonators has enabled great advances in optomechanics. Further improvements could allow for quantum-limited or quantum-enhanced applications at ambient temperature. Some of the remaining challenges include the integration of high-Q structures on a […]

Oliver, Lieven Vandersypen, Arzhang Ardavan, Roberta Sessoli | Summary: For the past three decades, nanoscience has widely affected many areas in physics, chemistry, and engineering, and has led to numerous fundamental discoveries as well as applications and products. Concurrently, quantum science and […]
Kavli Affiliate: Giordano Scappucci | First 5 Authors: Akito Noiri, Kenta Takeda, Takashi Nakajima, Takashi Kobayashi, Amir Sammak | Summary: Control of entanglement between qubits at distant quantum processors using a two-qubit gate is an essential function of a scalable, modular implementation of quantum computation. Among the many qubit platforms, spin qubits in silicon quantum […]
