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…
On the estimation of the Mori-Zwanzig memory integral
Yuanran Zhu, Jason M. Dominy, Daniele Venturi
We develop rigorous estimates and provably convergent approximations for the memory integral in the Mori-Zwanzig (MZ) formulation. The new theory is built upon rigorous mathematica…
Duality and Conditional Expectations in the Nakajima-Mori-Zwanzig Formulation
Jason M. Dominy, Daniele Venturi
We develop a new operator algebraic formulation of the Nakajima-Mori-Zwanzig (NMZ) method of projections. The new theory is built upon rigorous mathematical foundations, and it can…
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…
