Exact universal bounds on quantum dynamics and fast scrambling
Amit Vikram, Victor Galitski
Quantum speed limits such as the Mandelstam-Tamm or Margolus-Levitin bounds offer a quantitative formulation of the energy-time uncertainty principle that constrains dynamics over…
Bespoke Pulse Design for Robust Rapid Two-Qubit Gates with Trapped Ions
Seyed Shakib Vedaie, Eduardo J. Páez, Nhung H. Nguyen +2
Two-qubit gate performance is vital for scaling up ion-trap quantum computing. Optimized quantum control is needed to achieve reductions in gate-time and gate error-rate. We descri…

Tyler D. Ellison, Yu-An Chen, Arpit Dua +3
We construct Pauli topological subsystem codes characterized by arbitrary two-dimensional Abelian anyon theories--this includes anyon theories with degenerate braiding relations an…
Deterministic constant-depth preparation of the AKLT state on a quantum processor using fusion measurements
Kevin C. Smith, Eleanor Crane, Nathan Wiebe +1
The ground state of the spin-1 Affleck, Kennedy, Lieb and Tasaki (AKLT) model is a paradigmatic example of both a matrix product state and a symmetry-protected topological phase, a…
Lower Bounds on Quantum Annealing Times
Luis Pedro García-Pintos, Lucas T. Brady, Jacob Bringewatt +1
The adiabatic theorem provides sufficient conditions for the time needed to prepare a target ground state. While it is possible to prepare a target state much faster with more gene…
