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…
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…
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…
