Preparing approximate -fold cat states with the phase space instruction set
Shuyan Zhou, Andrew Lucas
The phase space instruction set is a continuous-variable universal gate set involving single-qubit rotations and qubit-dependent displacements on a single boson. Using these gates,…
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…
Lieb-Robinson bounds with exponential-in-volume tails
Ben T. McDonough, Chao Yin, Andrew Lucas +1
Lieb-Robinson bounds demonstrate the emergence of locality in many-body quantum systems. Intuitively, Lieb-Robinson bounds state that with local or exponentially decaying interacti…
Low-density parity-check codes as stable phases of quantum matter
Chao Yin, Andrew Lucas
Phases of matter with robust ground-state degeneracy, such as the quantum toric code, are known to be capable of robust quantum information storage. Here, we address the converse q…
Frobenius light cone and the shift unitary
Chao Yin, Andrew Lucas, David T. Stephen
We bound the time necessary to implement the shift unitary on a one-dimensional ring, both using local Hamiltonians and those with power-law interactions. This time is constrained…
Flux-charge symmetric theory of superconducting circuits
Andrew Osborne, Andrew Lucas
The quantum mechanics of superconducting circuits is derived by starting from a classical Hamiltonian dynamical system describing a dissipationless circuit, usually made of capacit…
