Ground and excited-state energies with analytic errors and short time evolution on a quantum computer
Timothy Stroschein, D. Castaldo, Markus Reiher·Jul 20, 2025
Accurately solving the Schr\"odinger equation remains a central challenge in computational physics, chemistry, and materials science. Here, we propose an alternative eigenvalue problem based on a system's autocorrelation function, avoiding direct ref...
Simultaneous determination of multiple low-energy eigenstates of many-body systems on a superconducting quantum processor
Huili Zhang, Yibin Guo, Guanglei Xu +4 more·Jul 20, 2025
The determination of the ground and low-lying excited states is critical in many studies of quantum chemistry and condensed-matter physics. Recent theoretical work proposes a variational quantum eigensolver using ancillary qubits to generate entangle...
Spiral renormalization group flow and universal entanglement spectrum of the non-Hermitian 5-state Potts model
Vic Vander Linden, Boris De Vos, Kevin Vervoort +2 more·Jul 19, 2025
The quantum $5$-state Potts model is known to possess a perturbative description using complex conformal field theory (CCFT), the analytic continuation of ``theory space" to a complex plane. To study the corresponding complex fixed point on the latti...
Toward scalable quantum computations of atomic nuclei
Chenyi Gu, Matthias Heinz, Oriel Kiss +1 more·Jul 19, 2025
We solve the nuclear two-body and three-body bound states via quantum simulations of pionless effective field theory on a lattice in position space. While the employed lattice remains small, the usage of local Hamiltonians including two- and three-bo...
Exact critical exponents of the Motzkin and Fredkin Chains
Olai B. Mykland, Zhao Zhang·Jul 19, 2025
The Motzkin and Fredkin chains are frustration-free models with exactly solvable ground states. Their $q$-deformations describe an exotic quantum phase transition from a disordered phase to an ordered one subject to domain-wall boundary conditions. U...
Towards Quantum Accelerated Large-scale Topology Optimization
Zisheng Ye, Wenxiao Pan·Jul 19, 2025
We present a new method that efficiently solves TO problems and provides a practical pathway to leverage quantum computing to exploit potential quantum advantages. This work targets on large-scale, multi-material TO challenges for three-dimensional (...
Multipartite entanglement from ditstrings for 1+1D systems
Zane Ozzello, Yannick Meurice·Jul 19, 2025
We show that multipartite entanglement can be used as an efficient way of identifying the critical points of 1+1D systems. We demonstrate this with the quantum Ising model, lattice $λφ^4$ approximated with qutrits, and arrays of Rydberg atoms. To do ...
Mitigating state transition errors during readout with a synchronized flux pulse
Yulong Li, Wuerkaixi Nuerbolati, Chunqing Deng +3 more·Jul 19, 2025
State transitions during qubit measurements are extremely detrimental to quantum tasks that rely on repeated measurements, such as quantum error correction. These state transitions can occur when excessive measurement power leads to qubit excitations...
Quantum State Preparation Based on LimTDD
Xin Hong, Chenjian Li, Aochu Dai +3 more·Jul 19, 2025
Quantum state preparation is a fundamental task in quantum computing and quantum information processing. With the rapid advancement of quantum technologies, efficient quantum state preparation has become increasingly important. This paper proposes a ...
Scalable modular architecture for universal quantum computation
Fernando Gago-Encinas, C. P. Koch·Jul 19, 2025
Universal quantum computing requires the ability to perform every unitary operation, i.e., evolution operator controllability. In view of developing resource-efficient quantum processing units (QPUs), it is important to determine how many local contr...
Spectator Leakage Elimination in CZ Gates via Tunable Coupler Interference on a Superconducting Quantum Processor
Peng Wang, Bing-Han Lu, Tian-Le Wang +11 more·Jul 19, 2025
Spectator-induced leakage poses a fundamental challenge to scalable quantum computing, particularly as frequency collisions become unavoidable in multi-qubit processors. We introduce a leakage mitigation strategy based on dynamically reshaping the sy...
Bipartite quantum states admitting a causal explanation
Minjeong Song, Arthur J. Parzygnat·Jul 18, 2025
The statistics of local measurements of joint quantum systems can sometimes be used to distinguish the spatiotemporal structure in which they were measured. We first prove that every bipartite separable density matrix is temporally compatible with di...
Diagnosing Device Performance in Rydberg-Ladder Gauge Simulators with Cumulative Probabilities and Filtered Mutual Information
Avi Kaufman, Muhammad Asaduzzaman, Zane Ozzello +3 more·Jul 18, 2025
We study bitstring measurements from the publicly available Aquila Rydberg-atom platform using a two-leg ladder that encodes a truncated lattice gauge model as a practical benchmark that can be directly implemented and simulated on current hardware. ...
Anomalous-magnetic-moment-enhanced Casimir effect
Daisuke Fujii, Katsumasa Nakayama, Kei Suzuki·Jul 18, 2025
We theoretically investigate the impact of the anomalous magnetic moment (AMM) of Dirac fermions on the fermionic Casimir effect under magnetic fields. We formulate it as an extension of the well-known Lifshitz formula. From our formula, we find that...
Exploring critical states of the quantum Rabi model via Hamiltonian variational ansätze
Mei Peng, Xu-Dan Xie, Dan-Bo Zhang·Jul 18, 2025
Characterizing quantum critical states towards the thermodynamic limit is essential for understanding phases of matter. The power of quantum simulators for preparing the critical states relies crucially on the structure of quantum circuits and in ret...
Role of quantum state texture in probing resource theories and quantum phase transition
Ayan Patra, Tanoy Kanti Konar, Pritam Halder +1 more·Jul 18, 2025
Building on the recently developed quantum state texture resource theory, we exhibit that the difference between maximum and minimum textures is a valid purity monotone in any dimension and provide a lower bound for existing purity measures. We intro...
Nonequilibrium steady states in multi-bath quantum collision models
Ronan McElvogue, Andrew K. Mitchell, Gabriel T. Landi +1 more·Jul 18, 2025
Collision models provide a simple and versatile setting to capture the dynamics of open quantum systems. The standard approach to thermalisition in this setting involves an environment of independent and identically-prepared thermal qubits, interacti...

Erik Bashore, Stefano Moretti, Timea Vitos·Jul 18, 2025
We propose a quantum algorithm for computing the n-gluon maximally helicity violating (MHV) tree-level scattering amplitude. We revisit a newly proposed method for unitarisation of non-unitary operations and present how this implementation can be use...
Quantum Blockchain Survey: Foundations, Trends, and Gaps
Saurav Ghosh, Niloy Deb Roy Mishu·Jul 18, 2025
Quantum computing poses fundamental risks to classical blockchain systems by undermining widely used cryptographic primitives. In response, two major research directions have emerged: post-quantum blockchains, which integrate quantum-resistant algori...
