System-bath model for quantum chemistry
Dmitry S. Golubev, Reza G. Shirazi, Vladimir V. Rybkin +3 more·Mar 10, 2026
We propose an approximate mapping of a molecular Hamiltonian to a Hamiltonian of qubits, which allows for high accuracy quantum chemistry calculations of vertical excitation energies of some molecules. The mapping is based on separating of a very sma...
Mitigating Frequency Learning Bias in Quantum Models via Multi-Stage Residual Learning
Ammar Daskin·Mar 10, 2026
Quantum machine learning models based on parameterized circuits can be viewed as Fourier series approximators. However, they often struggle to learn functions with multiple frequency components, particularly high-frequency or non-dominant ones; a phe...
Multi-tasking through quantum annealing
Jargalsaikhan Artag, Koki Awaya, Takumi Kanezashi +3 more·Mar 10, 2026
Quantum annealing approximately solves combinatorial optimization problems by leveraging the principles of adiabatic quantum systems. In this approach, the system's Hamiltonian evolves from an initial general state to a problem-specific state. This s...
Efficient Qubit Simulation of Hybrid Oscillator-Qubit Quantum Computation
Xi Lu, Bojko N. Bakalov, Yuan Liu·Mar 10, 2026
We introduce a framework for simulating hybrid oscillator-qubit quantum processors on qubit-only systems through position encoding. By encoding continuous-variable position and momentum wave functions into qubit amplitudes, our method efficiently sim...
Analytic formulae for non-local magic in bipartite systems of qutrits and ququints
Giorgio Busoni, John Gargalionis, Ewan N. V. Wallace +1 more·Mar 10, 2026
We conjecture analytic expressions for the non-local magic of bipartite pure qudit states of prime local dimension. Our construction relies on the Schmidt-aligned state attaining the minimum over local unitaries, a hypothesis that we support with num...
Parallel iQCC Enables 200 Qubit Scale Quantum Chemistry on Accelerated Computing Platforms Surpassing Classical Benchmarks in Ruthenium Catalysts
Seyyed Mehdi Hosseini Jenab, Brandon Henderson, Scott N. Genin·Mar 9, 2026
We introduce a parallel, GPU-accelerated implementation of the iterative qubit coupled cluster (iQCC) method that overcomes the exponential growth of the transformed Hamiltonian -- the principal bottleneck for classical emulation of quantum chemistry...
Large Language Model-Assisted Superconducting Qubit Experiments
Shiheng Li, Jacob M. Miller, Phoebe J. Lee +14 more·Mar 9, 2026
Superconducting circuits have demonstrated significant potential in quantum information processing and quantum sensing. Implementing novel control and measurement sequences for superconducting qubits is often a complex and time-consuming process, req...
Quantum algorithm for anisotropic diffusion and convection equations with vector norm scaling
Julien Zylberman, Thibault Fredon, Nuno F. Loureiro +1 more·Mar 9, 2026
In this work, we tackle the resolution of partial differential equations (PDEs) on digital quantum computers. Two fundamental PDEs are addressed: the anisotropic diffusion equation and the anisotropic convection equation. We present a quantum numeric...
Exploring pathways towards quantum advantage in quantum chemistry: the case of a molecule with half-Möbius topology
Samuele Piccinelli, Stefano Barison, Alberto Baiardi +8 more·Mar 9, 2026
We report quantum chemistry calculations performed on superconducting quantum processors for a molecule exhibiting the half-Möbius electronic topology originally introduced by Rončević et al. Using SqDRIFT, a randomized sample-based Krylov quantum di...
Symmetry-based perturbation theory for electronic structure calculations
Hiromichi Nishimura, Nam Nguyen, Tanvi Gujarati +1 more·Mar 9, 2026
We develop a multi-reference perturbation theory for electronic structure calculations based on symmetries of the Hamiltonian. The reference Hamiltonian in the symmetry-based perturbation theory (SBPT) is chosen such that it possesses more symmetries...
Microwave response of electrically driven spins in a three-qubit quantum processor
Tanner M. Janda, Heun Mo Yoo, Connor Nasseraddin +3 more·Mar 9, 2026
In electric dipole spin resonance (EDSR), a single spin is electrically driven in the field gradient produced by a micromagnet. While EDSR has enabled high fidelity gate operations in many devices, there are reports of unexpected non-linearities in t...
Experimental Realization of the Markov Chain Monte Carlo Algorithm on a Quantum Computer
Baptiste Claudon, Sergi Ramos-Calderer, Jean-Philip Piquemal·Mar 9, 2026
Quantum algorithms present a quadratically improved complexity over classical ones for certain sampling tasks. For instance, the Quantum Amplitude Estimation (QAE) algorithm promises to speedup the estimation of the mean of certain functions, given a...
Visualization of Three-Qubit Pure States with Separation of Local and Nonlocal Degrees of Freedom
Satoru Shoji·Mar 9, 2026
Understanding the structure of multi-qubit quantum states is essential for both quantum information research and education, yet intuitive visualization beyond the single-qubit Bloch sphere remains challenging. In this work, we propose a unified geome...
Quantum information advantage based on Bell inequalities
Rahul Jain, Srijita Kundu·Mar 9, 2026
Recently, Kretschmer et al. [KGD+25] presented an experimental demonstration of a proposed quantum information advantage protocol. We present an alternate proposal based on a relation derived from parallel-repeated CHSH games. Our memory measure is b...

Arun Govindankutty, Sudarshan K. Srinivasan·Mar 9, 2026
We present a scalable formal verification methodology for Quantum Phase Estimation (QPE) circuits. Our approach uses a symbolic qubit abstraction based on quantifier-free bit-vector logic, capturing key quantum phenomena, including superposition, rot...
Four-state discrimination for a pair of spin qubits via gate reflectometry
Aritra Sen, András Pályi·Mar 8, 2026
Single-electron spin qubits defined in quantum dots are used as building blocks of a semiconductor-based quantum computer. Readout in a scaled-up version of such a quantum computer is expected to rely on the Pauli Spin Blockade (PSB) mechanism. A des...

Timothy Heightman, Roman Aseguinolaza Gallo, Edward Jiang +3 more·Mar 8, 2026
Inferring the dynamical generator of a many-body quantum system from measurement data is essential for the verification, calibration, and control of quantum processors. When the system is open, this task becomes considerably harder than in the purely...
Deterministic Discrimination of Phase-Modified Permutation Oracles via Single Qubit Measurement
Owen Root·Mar 8, 2026
I study a promise problem for an unknown unitary operator acting on an $n$-qubit system. The operator is promised to take one of two forms: either it implements a fixed permutation of computational basis states, or it implements the same permutation ...
Gleason's theorem made simple: a Bloch-space perspective
Massimiliano Sassoli de Bianchi·Mar 8, 2026
Gleason's theorem is often cited as establishing the Born rule from the structure of Hilbert space, yet its original proof is mathematically sophisticated and rarely accessible to physicists. In this article we present a simple route to the essence o...
