Setting angles in quantum approximate optimization at utility-scale
Maosheng Guo, Joel Jurado Diaz, Anurag Ramesh +16
The quantum approximate optimization algorithm (QAOA) is a powerful heuristic that seeks to solve combinatorial optimization problems using quantum hardware and classical optimizat…
Amplification of bosonic interactions through squeezing in the presence of decoherence
Ankit Tiwari, Cecilia Cormick, Christian Arenz
We consider the amplification of bosonic interactions through parametric control that implements squeezing along orthogonal quadratures. We show that bosonic interactions described…
Loss tolerant cross-Kerr enhancement via modulated squeezing
Ankit Tiwari, Daniel Burgarth, Linran Fan +2
We develop squeezing protocols to enhance cross-Kerr interactions. We show that through alternating between squeezing along different quadratures of a single photonic mode, the cro…
Entanglement engineering of optomechanical systems by reinforcement learning
Li-Li Ye, Christian Arenz, Joseph M. Lukens +1
Entanglement is fundamental to quantum information science and technology, yet controlling and manipulating entanglement -- so-called entanglement engineering -- for arbitrary quan…
Learning How to Dynamically Decouple
Arefur Rahman, Daniel J. Egger, Christian Arenz
Current quantum computers suffer from noise that stems from interactions between the quantum system that constitutes the quantum device and its environment. These interactions can…
