Simulation Complexity of Many-Body Localized Systems
Adam Ehrenberg, Abhinav Deshpande, Christopher L. Baldwin +2
We use complexity theory to rigorously investigate the difficulty of classically simulating evolution under many-body localized (MBL) Hamiltonians. Using the defining feature that…
Optimal State Transfer and Entanglement Generation in Power-law Interacting Systems
Minh C. Tran, Abhinav Deshpande, Andrew Y. Guo +2
We present an optimal protocol for encoding an unknown qubit state into a multiqubit Greenberger-Horne-Zeilinger-like state and, consequently, transferring quantum information in l…
Entanglement bounds on the performance of quantum computing architectures
Zachary Eldredge, Leo Zhou, Aniruddha Bapat +4
There are many possible architectures of qubit connectivity that designers of future quantum computers will need to choose between. However, the process of evaluating a particular…
Quantum Approximate Optimization of the Long-Range Ising Model with a Trapped-Ion Quantum Simulator
G. Pagano, A. Bapat, P. Becker +13
Quantum computers and simulators may offer significant advantages over their classical counterparts, providing insights into quantum many-body systems and possibly improving perfor…
Unitary Entanglement Construction in Hierarchical Networks
Aniruddha Bapat, Zachary Eldredge, James R. Garrison +3
The construction of large-scale quantum computers will require modular architectures that allow physical resources to be localized in easy-to-manage packages. In this work, we exam…
