Quantum Machine Learning for Predicting Binding Free Energies in Structure-Based Virtual Screening
Pei-Kun Yang·Jul 24, 2025
In structure-based virtual screening, it is often necessary to evaluate the binding free energy of protein-ligand complexes by considering not only molecular conformations but also how these structures shift and rotate in space. The number of possibl...
Multi-qubit Rydberg gates between distant atoms
Antonis Delakouras, Georgios Doultsinos, David Petrosyan·Jul 22, 2025
We propose an efficient protocol to realize multi-qubit gates in arrays of neutral atoms. The atoms encode qubits in the long-lived hyperfine sublevels of the ground electronic state. To realize the gate, we apply a global laser pulse to transfer the...
Deterministic Quantum Search via Recursive Oracle Expansion
John Burke, C. McGoldrick·Jul 21, 2025
We introduce a novel deterministic quantum search algorithm that provides a practical alternative to conventional probabilistic search approaches. Our scheme eliminates the inherent uncertainty of quantum search without relying on arbitrary phase rot...
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 (...
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...
A quantum algorithm for the n-gluon MHV scattering amplitude
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...
Splitting of the three-body Förster resonance in Rb Rydberg atoms as a measure of dipole-dipole interaction strength
I. I. Ryabtsev, I. N. Ashkarin, I. I. Beterov +4 more·Jul 18, 2025
Three-body Förster resonances controlled by a dc electric field are of interest for the implementation of three-qubit quantum gates with single atoms in optical traps using their laser excitation into strongly interacting Rydberg states. In our recen...
Fast charge noise sensing using a spectator valley state in a singlet-triplet qubit
David W. Kanaar, Yasuo Oda, M. Gyure +1 more·Jul 18, 2025
Semiconductor spin qubits are a promising platform for quantum computing but remain vulnerable to charge noise. Accurate, in situ measurement of charge noise could enable closed-loop control and improve qubit performance. Here, we propose a method fo...

Yong-bok Lee, Connor Devitt, Xu Zhu +3 more·Jul 17, 2025
Superconducting quantum computers have emerged as a leading platform for next-generation computing, offering exceptional scalability and unprecedented computational speeds. However, scaling these systems to millions of qubits for practical applicatio...
Entanglement-efficiency trade-offs in the fusion-based generation of photonic GHZ-like states

Diego Ruiz, Jérémie Guillaud, Christophe Vuillot +1 more·Jul 16, 2025
Magic state distillation enables universal fault-tolerant quantum computation by implementing non-Clifford gates via the preparation of high-fidelity magic states. However, it comes at the cost of substantial logical-level overhead in both space and ...

Quantum Circuits Are Just a Phase
Chris Heunen, Louis Lemonnier, Christopher McNally +1 more·Jul 15, 2025
