Parity Cross-Resonance: A Multiqubit Gate
Xuexin Xu, Siyu Wang, Radhika H. Joshi +2 more·Aug 14, 2025
We present a native three-qubit entangling gate that exploits engineered interactions to realize control-control-target and control-target-target operations in a single coherent step. Unlike conventional decompositions into multiple two-qubit gates, ...
QB Ground State Energy Estimation Benchmark
Nicole Bellonzi, Joshua T. Cantin, M. Jangrouei +14 more·Aug 14, 2025
Ground State Energy Estimation (GSEE) is a central problem in quantum chemistry and condensed matter physics, demanding efficient algorithms to solve complex electronic structure calculations. This work introduces a structured benchmarking framework ...
Scalable platform for qudit-based quantum computing using polar molecules
Soleh Kh. Muminov, Evgeniy O. Kiktenko, Anastasiia S. Nikolaeva +4 more·Aug 14, 2025
We propose a scalable qudit-based quantum processor using rotational states of polar molecules. Previously, molecular internal states were used to enlarge Hilbert space, whereas our approach uses optical tweezer arrays to achieve scalable architectur...
Efficient Quantum Information-Inspired Ansatz for Variational Quantum Eigensolver Algorithm: Applications to Atomic Systems
A. Kalam, Prasenjit Deb, A. Sakurai +3 more·Aug 14, 2025
We present a quantum information-inspired ansatz for the variational quantum eigensolver (VQE) and demonstrate its efficacy in calculating ground-state energies of atomic systems. Instead of adopting a heuristic approach, we start with an approximate...
Simulating Mass-Dependent Decoherence in Quantum Computers: Baseline Signatures for Testing Gravity-Induced Collapse
V. Balaji, Samuel Punch·Aug 14, 2025
We present a quantum computing simulation study of mass-dependent decoherence models inspired by Penrose's gravity-induced collapse hypothesis. According to objective reduction (OR) theory, quantum superpositions become unstable when the gravitationa...
Magic tricycles: Efficient magic state generation with finite block-length quantum LDPC codes
Varun Menon, J. P. Bonilla-Ataides, Rohan K. Mehta +3 more·Aug 14, 2025
The preparation of high-fidelity non-Clifford (magic) states is an essential subroutine for universal quantum computation, but imposes substantial space-time overhead. Magic state factories based on high rate and distance quantum low-density parity c...
Quantum Wavefront Correction Via Machine Learning for Satellite‐to‐Earth CV‐QKD
Nathan K. Long, Ziqing Wang, B. Dix-Matthews +4 more·Aug 14, 2025
State‐of‐the‐art free‐space continuous‐variable quantum key distribution (CV‐QKD) protocols use phase reference pulses to modulate the wavefront of a real local oscillator at the receiver, thereby compensating for wavefront distortions caused by atmo...
Decoded quantum interferometry under noise
Kaifeng Bu, Weichen Gu, Dax Enshan Koh +1 more·Aug 14, 2025
Decoded quantum interferometry (DQI) is a recently proposed quantum optimization algorithm that exploits sparsity in the Fourier spectrum of objective functions, with the potential for exponential speedups over classical algorithms on suitably struct...
Quantum Visual Fields with Neural Amplitude Encoding
Shuteng Wang, C. Theobalt, Vladislav Golyanik·Aug 14, 2025
Quantum Implicit Neural Representations (QINRs) include components for learning and execution on gate-based quantum computers. While QINRs recently emerged as a promising new paradigm, many challenges concerning their architecture and ansatz design, ...
A Constant-Time Hardware Architecture for the CSIDH Key-Exchange Protocol
Sina Bagheri, Masoud Kaveh, Francisco Hernando-Gallego +2 more·Aug 14, 2025
The commutative supersingular isogeny Diffie-Hellman (CSIDH) algorithm is a promising post-quantum key exchange protocol, notable for its exceptionally small key sizes, but hindered by computationally intensive key generation. Furthermore, practical ...

Variational quantum algorithms have emerged as a cornerstone of contemporary quantum algorithms research. While they have demonstrated considerable promise in solving problems of practical interest, efficiently determining the minimal quantum resourc...
Quantum recurrences and the arithmetic of Floquet dynamics
Amit Anand, Dinesh Valluri, Jack Davis +1 more·Aug 13, 2025
The Poincaré recurrence theorem shows that conservative systems in a bounded region of phase space eventually return arbitrarily close to their initial state after a finite amount of time. An analogous behavior occurs in certain quantum systems where...
