TwinCheck: Evidence-Grounded Negative-Twin Verification for Stateful Tool Agents
Jiaxuan Dai, Tianyi Huang
A single locally plausible tool call can derail an otherwise successful agent trajectory. Suspicion alone does not justify intervention, because the replacement itself can introduc…
On the local equivalence of trapped-ion two-qudit gates
Nikita V. Semenin, Pavel A. Kamenskikh, Ilia V. Zalivako +2
We derive a necessary condition of the local equivalence between two-qudit gates in terms of singular values of transformed gate matrices. This condition is valid for arbitrary qud…
Experimental factoring integers using fixed-point-QAOA with a trapped-ion quantum processor
Ilia V. Zalivako, Andrey Yu. Chernyavskiy, Anastasiia S. Nikolaeva +10
Factoring integers is considered as a computationally-hard problem for classical methods, whereas there exists polynomial-time Shor's quantum algorithm for solving this task. Howev…
Scalable improvement of the generalized Toffoli gate realization using trapped-ion-based qutrits
Anastasiia S. Nikolaeva, Ilia V. Zalivako, Alexander S. Borisenko +8
An efficient implementation of the Toffoli gate is of conceptual importance for running various quantum algorithms, including Grover's search and Shor's integer factorization. Howe…
Supervised binary classification of small-scale digit images and weighted graphs with a trapped-ion quantum processor
Ilia V. Zalivako, Alexander I. Gircha, Evgeniy O. Kiktenko +14
Here we present the results of benchmarking a quantum processor based on trapped Yb ions by performing basic quantum machine learning algorithms. Using a quantum-enha…
Towards multiqudit quantum processor based on a Yb ion string: Realizing basic quantum algorithms
Ilia V. Zalivako, Anastasiia S. Nikolaeva, Alexander S. Borisenko +12
We demonstrate a quantum processor based on a 3D linear Paul trap that uses Yb ions with 8 individually controllable four-level qudits (ququarts), which is computatio…
Demonstration of a parity-time symmetry breaking phase transition using superconducting and trapped-ion qutrits
Alena S. Kazmina, Ilia V. Zalivako, Alexander S. Borisenko +21
Scalable quantum computers hold the promise to solve hard computational problems, such as prime factorization, combinatorial optimization, simulation of many-body physics, and quan…
Continuous dynamical decoupling of optical Yb qudits with radiofrequency fields
Ilia V. Zalivako, Alexander S. Borisenko, Ilya A. Semerikov +9
The use of multilevel quantum information carriers, also known as qudits, attracts a significant deal of interest as a way for further scalability of quantum computing devices. How…
Realizing quantum gates with optically-addressable Yb ion qudits
M. A. Aksenov, I. V. Zalivako, I. A. Semerikov +6
The use of multilevel information carriers, also known as qudits, is a promising path for exploring scalability of quantum computing devices. Here we present a proof-of-principle r…
