Jennifer Sleeman, J. Dorband, M. Halem·Jan 31, 2020
Understanding how the D-Wave quantum computer could be used for machine learning problems is of growing interest. Our work explores the feasibility of using the D-Wave as a sampler for a machine learning task. We describe a hybrid method that combine...
Entanglement generation via power-of-swap operations between dynamic electron-spin qubits
H. Lepage, A. Lasek, D. Arvidsson-Shukur +1 more·Jan 15, 2020
Surface acoustic waves (SAWs) can create moving quantum dots in piezoelectric materials. Here we show how electron-spin qubits located on dynamic quantum dots can be entangled. Previous theoretical and numerical models of quantum-dot entanglement gen...
High-Fidelity Control, Detection, and Entanglement of Alkaline-Earth Rydberg Atoms
I. Madjarov, J. Covey, Adam L. Shaw +7 more·Jan 13, 2020
Trapped neutral atoms have become a prominent platform for quantum science, where entanglement fidelity records have been set using highly-excited Rydberg states. However, controlled two-qubit entanglement generation has so far been limited to alkali...
QSOR: Quantum-Safe Onion Routing
Zsolt Tujner, Thomas Rooijakkers, M. V. Heesch +1 more·Jan 10, 2020
In this work, we propose a study on the use of post-quantum cryptographic primitives for the Tor network in order to make it safe in a quantum world. With this aim, the underlying keying material has first been analysed. We observe that breaking the ...
