State Machine Model for The Update Framework (TUF)
Brian Romansky, T. Mazzuchi, S. Sarkani·Feb 25, 2025
The Update Framework or TUF was developed to address several known weaknesses that have been observed in software update distribution and validation systems. Unlike conventional secure software distribution methods where there may be a single digital...
Repeated interaction scheme for the quantum simulation of non-Markovian electron transfer dynamics.
Lea K. Northcote, Matthew S. Teynor, Gemma C Solomon·Feb 25, 2025
Quantum algorithms have the potential to revolutionize our understanding of open quantum systems in chemistry. In this work, we demonstrate that a repeated interaction model, which could serve as the foundation for a digital quantum algorithm, can ef...
Disentangling quantum autoencoder
Adithya Sireesh, Abdulla Alhajri, M. Kim +1 more·Feb 25, 2025
Entangled quantum states are highly sensitive to noise, which makes it difficult to transfer them over noisy quantum channels or to store them in quantum memory. Here, we propose the disentangling quantum autoencoder (DQAE) to encode entangled states...
Optimal symbolic construction of matrix product operators and tree tensor network operators
Hazar cCakir, Richard M. Milbradt, C. Mendl·Feb 25, 2025
This research introduces an improved framework for constructing matrix product operators (MPOs) and tree tensor network operators (TTNOs), crucial tools in quantum simulations. A given (Hamiltonian) operator typically has a known symbolic"sum of oper...
Transformation-Free Generation of a Quasi-Diabatic Representation from the State-Average Orbital-Optimized Variational Quantum Eigensolver.
Silvie Illésová, Martin Beseda, Saad Yalouz +2 more·Feb 25, 2025
In the present work, we examine how the recent quantum-computing algorithm known as the state-average orbital-optimized variational quantum eigensolver (SA-OO-VQE), viewed within the context of quantum chemistry as a type of multiconfiguration self-c...
STQS: A Unified System Architecture for Spatial Temporal Quantum Sensing
Anastashia Jebraeilli, Chenxu Liu, Keyi Yin +4 more·Feb 25, 2025
We present STQS, a unified system architecture for spatiotemporal quantum sensing that interlaces four key quantum components: sensing, memory, communication, and computation. By employing a comprehensive gate-based framework, we systemically explore...
Indefinite Time Directed Quantum Metrology
Gaurang Agrawal, Pritam Halder, A. Sende·Feb 25, 2025
We explore the performance of the metrology scheme by employing a quantum time flip during encoding, a specific case of processes with indefinite time direction, which we refer to as indefinite time directed metrology (ITDM). In the case of single pa...
Pauli Measurements Are Not Optimal for Single-Copy Tomography
Jayadev Acharya, Abhilash Dharmavarapu, Yuhan Liu +1 more·Feb 25, 2025
Quantum state tomography is a fundamental problem in quantum computing. Given n copies of an unknown N-qubit state ρ∈ℂd× d,d=2N, the goal is to learn the state up to an accuracy ε in trace distance, say with at least constant probability 0.99. We are...
Quantum-Annealing-Based Sum Rate Maximization for Multi-UAV-Aided Wireless Networks
Seon-Geun Jeong, Pham Dang Anh Duc, Q. Do +7 more·Feb 25, 2025
In wireless communication networks, it is difficult to solve many NP-hard problems owing to computational complexity and high cost. Recently, quantum annealing (QA) based on quantum physics was introduced as a key enabler for solving optimization pro...
Maximal Magic for Two-qubit States
Qiaofeng Liu, Ian Low, Zhewei Yin·Feb 24, 2025
Magic is a quantum resource essential for universal quantum computation and represents the deviation of quantum states from those that can be simulated efficiently using classical algorithms. Using the Stabilizer Rényi Entropy (SRE), we investigate t...

Jasper Johannes Postema, Servaas J. J. M. F. Kokkelmans·Feb 24, 2025
Encoding quantum information in a quantum error correction (QEC) code offers protection against decoherence and enhances the fidelity of qubits and gate operations. One of the fundamental challenges of QEC is to construct codes with asymptotically go...
