Impact of Error Rate Misreporting on Resource Allocation in Multi-tenant Quantum Computing and Defense
Subrata Das, Swaroop Ghosh·Apr 5, 2025
Cloud-based quantum service providers allow multiple users to run programs on shared hardware concurrently to maximize resource utilization and minimize operational costs. This multi-tenant computing (MTC) model relies on the error parameters of the ...
Quantum parallel information exchange (QPIE) hybrid network with transfer learning
Ziqing Guo, Alex Khan, Victor Sheng +2 more·Apr 5, 2025
Quantum machine learning (QML) has emerged as an innovative framework that has the potential to uncover complex patterns by leveraging the ability of quantum systems to simulate and exploit high-dimensional latent spaces, particularly in learning tas...
CutQAS: Topology-aware quantum circuit cutting via reinforcement learning
Abhishek Sadhu, Aritra Sarkar, Akash Kundu·Apr 5, 2025
Simulating molecular systems on quantum processors has the potential to surpass classical methods in computational resource efficiency. The limited qubit connectivity, small processor size, and short coherence times of near-term quantum hardware cons...
Symmetrizing the constraints: Density matrix renormalization group for constrained lattice models
Ting-Tung Wang, Xiaoxue Ran, Z. Y. Meng·Apr 5, 2025
We develop a density matrix renormalization group (DMRG) algorithm for constrained quantum lattice models that successfully {\it{implements the local constraints as symmetries in the contraction of the matrix product states and matrix product operato...
Gravitational redshift of broadband relativistic quantum photons
Alessio Lapponi, Alessandro Ferreri, David Edward Bruschi·Apr 4, 2025
We employ linearized quantum gravity to study gravitational redshift of photons in the context of relativistic and quantum physics, where photons interact in flat spacetime with a classical massive body via graviton exchange. We find that gravitation...
A Reconfigurable Time-Domain In-Memory Computing Macro using FeFET-Based CAM with Multilevel Delay Calibration in 28 nm CMOS
Jeries Mattar, Mor M. Dahan, Stefan Dunkel +5 more·Apr 4, 2025
Time-domain nonvolatile in-memory computing (TD-nvIMC) offers a promising pathway to reduce data movement and improve energy efficiency by encoding computation in delay rather than voltage or current. This work presents a fully integrated and reconfi...
Experiment indicates that Realism, not Locality, is false in Quantum Mechanics
Mónica Agüero, Juliana Bordieu, Alejandro Hnilo +2 more·Apr 4, 2025
The interpretation of the meaning of Quantum Mechanics has faced controversy since its inception. Bell's inequalities are a touchstone in this controversy. Their observed violation demonstrates that at least one of the hypotheses involved in their de...
Paying attention to long-range electron correlation: a size-independent deep-learning approach to predicting molecules' electronic energies from one- and two-electron integrals
Valerii Chuiko, Giovanni B. Da Rosa, Paul W. Ayers·Apr 4, 2025
We propose a descriptor for molecular electronic structure that is based solely on the one- and two-electron integrals but is translationally, rotationally, and unitarily invariant. Then, directly exploiting size consistency, we train and fine tune a...
Approximate normalizations for approximate density functionals
Adam Clay, Kiril Datchev, Wenlan Miao +3 more·Apr 4, 2025
It seems self-evident that a density functional calculation should be normalized to the number of electrons in the system. We present multiple examples where the accuracy of the approximate energy is improved (sometimes greatly) by violating this bas...
Wave-particle duality in the measurement of gravitational radiation
Hudson A. Loughlin, Germain Tobar, Evan D. Hall +1 more·Apr 4, 2025
In a consistent description of the quantum measurement process, whether the wave or particle-like aspect of a system is revealed depends on the details of the measurement chain, and cannot be interpreted as an objective fact about the system independ...
Independent e- and m-anyon confinement in the parallel field toric code on non-square lattices
Simon M. Linsel, Lode Pollet, Fabian Grusdt·Apr 4, 2025
Kitaev's toric code has become one of the most studied models in physics and is highly relevant to the fields of both quantum error correction and condensed matter physics. Most notably, it is the simplest known model hosting an extended, deconfined ...
Reducing quantum error correction overhead using soft information
Joonas Majaniemi, Elisha S. Matekole·Apr 4, 2025
Imperfect measurements are a prevalent source of error across quantum computing platforms, significantly degrading the logical error rates achievable on current hardware. To mitigate this issue, rich measurement data referred to as soft information h...
Quantum conditional mutual information as a probe of measurement-induced entanglement phase transitions
Yuichi Otsuka, Kazuhiro Seki, Seiji Yunoki·Apr 4, 2025
We propose that the quantum conditional mutual information (QCMI), computed with a suitably chosen partition of the system, serves as a powerful probe for detecting measurement-induced entanglement phase transitions in monitored quantum circuits. To ...
