Low-depth fermion routing without ancillas
Nathan Constantinides, Jeffery Yu, Dhruv Devulapalli +6
Routing is the task of permuting qubits in such a way that quantum operations can be parallelized maximally, given constraints on the hardware geometry. When simulating fermions in…
A vapor-cavity-QED system for quantum computation and communication
Sharoon Austin, Dhruv Devulapalli, Khoi Hoang +3
In this work, we propose performing key operations in quantum computation and communication using room-temperature atoms moving across a grid of high-quality-factor, small-mode-vol…
The Complexity of Thermalization in Finite Quantum Systems
Dhruv Devulapalli, T. C. Mooney, James D. Watson
Thermalization is the process through which a physical system evolves toward a state of thermal equilibrium. Determining whether or not a physical system will thermalize from an in…
Quantum Routing and Entanglement Dynamics Through Bottlenecks
Dhruv Devulapalli, Chao Yin, Andrew Y. Guo +4
To implement arbitrary quantum circuits in architectures with restricted interactions, one may effectively simulate all-to-all connectivity by routing quantum information. We consi…
Optimal Routing Protocols for Reconfigurable Atom Arrays
Nathan Constantinides, Ali Fahimniya, Dhruv Devulapalli +5
Neutral atom arrays have emerged as a promising platform for both analog and digital quantum processing. Recently, devices capable of reconfiguring arrays during quantum processes…
Toward a 2D Local Implementation of Quantum LDPC Codes
Noah Berthusen, Dhruv Devulapalli, Eddie Schoute +4
Geometric locality is an important theoretical and practical factor for quantum low-density parity-check (qLDPC) codes which affects code performance and ease of physical realizati…
Efficiently verifiable quantum advantage on near-term analog quantum simulators
Zhenning Liu, Dhruv Devulapalli, Dominik Hangleiter +4
Existing schemes for demonstrating quantum computational advantage are subject to various practical restrictions, including the hardness of verification and challenges in experimen…
Quantum Routing with Teleportation
Dhruv Devulapalli, Eddie Schoute, Aniruddha Bapat +2
We study the problem of implementing arbitrary permutations of qubits under interaction constraints in quantum systems that allow for arbitrarily fast local operations and classica…
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…
