Focusing Surface-Acoustic-Wave Resonators on Thin-Film Lithium Niobate with Transverse-Mode Suppression
Ryo Sasaki, Ryusuke Hisatomi, Rekishu Yamazaki +3 more·Mar 11, 2026
Surface-acoustic-wave (SAW) resonators are a promising platform for constructing hybrid quantum systems, where confined acoustic waves enable strong interaction with various physical systems. Focusing SAW resonators, reducing mode volume while suppre...
Unitary imaginary time evolution and ground state preparation using multi-copy protocols
Tal Schwartzman, Torsten V. Zache, Hannes Pichler +1 more·Mar 11, 2026
Efficient low-energy state preparation is a key objective in quantum computation and quantum simulation. Quantum imaginary-time evolution replaces real-time dynamics with imaginary-time dynamics, exponentially suppressing higher-energy eigenstates. W...
Reference Architecture of a Quantum-Centric Supercomputer
Seetharami Seelam, Jerry M. Chow, Antonio Córcoles +10 more·Mar 11, 2026
Quantum computers have demonstrated utility in simulating quantum systems beyond brute-force classical approaches. As the community builds on these demonstrations to explore using quantum computing for applied research, algorithms and workflows have ...
Hybridlane: A Software Development Kit for Hybrid Continuous-Discrete Variable Quantum Computing
Jim Furches, Timothy J. Stavenger, Carlos Ortiz Marrero·Mar 11, 2026
Hybrid quantum computing systems that combine discrete-variable qubits with continuous-variable qumodes offer promising advantages for quantum simulation, error correction, and sensing applications. However, existing quantum software frameworks lack ...
Universal purification dynamics in real non-unitary quantum processes
Federico Gerbino, Donghoon Kim, Guido Giachetti +2 more·Mar 11, 2026
We study purification dynamics in monitored quantum processes governed by ensembles of quantum circuits in different random-matrix symmetry classes. We analyze the universal aspects that emerge away from the measurement induced phase transition and i...
Hybrid Photonic Quantum Reservoir Computing for High-Dimensional Financial Surface Prediction
Fyodor Amanov, Azamkhon Azamov·Mar 11, 2026
We propose a hybrid photonic quantum reservoir computing (QRC) framework for swaption surface prediction. The pipeline compresses 224-dimensional surfaces to a 20-dimensional latent space via a sparse denoising autoencoder, extracts 1,215 Fock-basis ...
Optical quantum teleportation with known amplitude distorting factors of teleported qubits
Mikhail S. Podoshvedov, Sergey A. Podoshvedov·Mar 11, 2026
We develop a quantum teleportation protocol of an unknown optical single rail qubit using a hybrid quantum channel composed of continuous variable (CV) states of certain parity. The quantum channel is characterized by two parameters: a squeezing para...
Entanglement distribution among distinct mechanical nodes in a quantum network
Zhi-Yuan Fan, Liu-Yong Cheng·Mar 11, 2026
We propose two schemes to achieve remote entanglement distribution between two mechanical nodes with a significant frequency mismatch, based on optomechanical systems. The first scheme utilizes the physical mechanism to redistribute the quantum entan...
Quantum entanglement provides a competitive advantage in adversarial games
Peiyong Wang, Kieran Hymas, James Quach·Mar 11, 2026
Whether uniquely quantum resources confer advantages in fully classical, competitive environments remains an open question. Competitive zero-sum reinforcement learning is particularly challenging, as success requires modelling dynamic interactions be...
Layered Performance Analysis of TLS 1.3 Handshakes: Classical, Hybrid, and Pure Post-Quantum Key Exchange
David G'omez-Cambronero, D. Munteanu, Ana Isabel Gonz'alez-Tablas·Mar 11, 2026
In this paper, we present a laboratory study focused on the impact of post-quantum cryptography (PQC) algorithms on multiple layers of stateful HTTP over TLS transactions: the TCP handshake, the intermediate TCP-TLS layer, the TLS handshake, the inte...
