Advances in High Dimensional Quantum Entanglement
Manuel Erhard, Mario Krenn, Anton Zeilinger
Since its discovery in the last century, quantum entanglement has challenged some of our most cherished classical views, such as locality and reality. Today, the second quantum rev…
Quantum Computing at the Frontiers of Biological Sciences
Prashant S. Emani, Jonathan Warrell, Alan Anticevic +15
The search for meaningful structure in biological data has relied on cutting-edge advances in computational technology and data science methods. However, challenges arise as we pus…
Computer-inspired concept for high-dimensional multipartite quantum gates
Xiaoqin Gao, Manuel Erhard, Anton Zeilinger +1
An open question in quantum optics is how to manipulate and control complex quantum states in an experimentally feasible way. Here we present concepts for transformations of high-d…
Resource-efficient digital quantum simulation of -level systems for photonic, vibrational, and spin- Hamiltonians
Nicolas P. D. Sawaya, Tim Menke, Thi Ha Kyaw +3
Simulation of quantum systems is expected to be one of the most important applications of quantum computing, with much of the theoretical work so far having focused on fermionic an…
Wavefunction positivization via automatic differentiation
Giacomo Torlai, Juan Carrasquilla, Matthew T. Fishman +2
We introduce a procedure to systematically search for a local unitary transformation that maps a wavefunction with a non-trivial sign structure into a positive-real form. The trans…
Expressibility and entangling capability of parameterized quantum circuits for hybrid quantum-classical algorithms
Sukin Sim, Peter D. Johnson, Alan Aspuru-Guzik
Parameterized quantum circuits play an essential role in the performance of many variational hybrid quantum-classical (HQC) algorithms. One challenge in implementing such algorithm…
