Helios: A 98-qubit trapped-ion quantum computer
Anthony Ransford, M. S. Allman, Jake Arkinstall +183
We report on Quantinuum Helios, a 98-qubit trapped-ion quantum processor based on the quantum charge-coupled device (QCCD) architecture. Helios features Ba hyperfine…
-mixers: analytical and numerical results for QAOA
Zhihui Wang, Nicholas C. Rubin, Jason M. Dominy +1
The Quantum Alternating Operator Ansatz (QAOA) is a promising gate-model meta-heuristic for combinatorial optimization. Applying the algorithm to problems with constraints presents…
Beyond Complete Positivity
Jason M. Dominy, Daniel A. Lidar
We provide a general and consistent formulation for linear subsystem quantum dynamical maps, developed from a minimal set of postulates, primary among which is a relaxation of the…
Evolution prediction from tomography
Jason M. Dominy, Lorenzo Campos Venuti, Alireza Shabani +1
Quantum process tomography provides a means of measuring the evolution operator for a system at a fixed measurement time . The problem of using that tomographic snapshot to pred…
A general framework for complete positivity
Jason M. Dominy, Alireza Shabani, Daniel A. Lidar
Complete positivity of quantum dynamics is often viewed as a litmus test for physicality, yet it is well known that correlated initial states need not give rise to completely posit…
Analysis of the quantum Zeno effect for quantum control and computation
Jason M. Dominy, Gerardo A. Paz-Silva, A. T. Rezakhani +1
Within quantum information, many methods have been proposed to avoid or correct the deleterious effects of the environment on a system of interest. In this work, expanding on our e…
