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…
Importance of the spectral gap in estimating ground-state energies
Abhinav Deshpande, Alexey V. Gorshkov, Bill Fefferman
The field of quantum Hamiltonian complexity lies at the intersection of quantum many-body physics and computational complexity theory, with deep implications to both fields. The ma…
Implementing a Fast Unbounded Quantum Fanout Gate Using Power-Law Interactions
Andrew Y. Guo, Abhinav Deshpande, Su-Kuan Chu +6
The standard circuit model for quantum computation presumes the ability to directly perform gates between arbitrary pairs of qubits, which is unlikely to be practical for large-sca…
Complexity of Fermionic Dissipative Interactions and Applications to Quantum Computing
Oles Shtanko, Abhinav Deshpande, Paul S. Julienne +1
Interactions between particles are usually a resource for quantum computing, making quantum many-body systems intractable by any known classical algorithm. In contrast, noise is ty…
Hierarchy of linear light cones with long-range interactions
Minh C. Tran, Chi-Fang Chen, Adam Ehrenberg +6
In quantum many-body systems with local interactions, quantum information and entanglement cannot spread outside of a linear light cone, which expands at an emergent velocity analo…
