Near-optimal entanglement-communication tradeoffs for remote state preparation
Srijita Kundu, Olivier Lalonde·Feb 10, 2026
We study the following task: Alice is given a classical description of a rank-$k$ projector $P$ on $\mathbb{C}^d$, and Alice and Bob want to prepare the quantum state $P/k$ on Bob's side using shared entanglement and classical communication. The gene...
Historical Debates over the Physical Reality of the Wave Function
Jacob A. Barandes·Feb 10, 2026
This paper provides a detailed historical account of early debates over wave-function realism, the modern term for the view that the wave function of quantum theory is physically real. As this paper will show, the idea of physical waves associated wi...
Efficient and deterministic high-dimensional controlled-swap gates on hybrid linear optical systems with high fidelity
Gui-Long Jiang, Jun-Bin Yuan, Wen-Qiang Liu +1 more·Feb 10, 2026
Implementation of quantum logic gates with linear optical elements plays a prominent role in quantum computing due to the relatively easier manipulation and realization. We present efficient schemes to implement controlled-NOT (CNOT) gate and control...
Separating Quantum and Classical Advice with Good Codes
John Bostanci, Andrew Huang, Vinod Vaikuntanathan·Feb 10, 2026
We show an unconditional classical oracle separation between the class of languages that can be verified using a quantum proof ($\mathsf{QMA}$) and the class of languages that can be verified with a classical proof ($\mathsf{QCMA}$). Compared to the ...
The Trouble with Weak Values
Jacob A. Barandes·Feb 10, 2026
In quantum theory, a weak value is a complex number with a somewhat technical definition: it is a ratio whose numerator is the matrix element of a self-adjoint operator and whose denominator is the inner product of a corresponding pair of state vecto...
Surrogate-Guided Quantum Discovery in Black-Box Landscapes with Latent-Quadratic Interaction Embedding Transformers
Saisubramaniam Gopalakrishnan, Dagnachew Birru·Feb 10, 2026
Discovering configurations that are both high-utility and structurally diverse under expensive black-box evaluation and strict query budgets remains a central challenge in data-driven discovery. Many classical optimizers concentrate on dominant modes...
Compressing Quantum Fisher Information
Rui Jie Tang, Jeremy Guenza Marcus, Noah Lupu-Gladstein +5 more·Feb 10, 2026
We show that the quantum Fisher information about any phase parameter encoded in a family of pure quantum states can be faithfully compressed into a single qubit, accompanied by a logarithmic amount of classical bits. When the phase is encoded into m...
Quantum Correlation Dynamics Subjected to Quantum Reset-Driven Environment
R. Jafari, Ali Asadian, Mehdi Biderang +1 more·Feb 10, 2026
We study two central qubits interacting with a transverse-field Ising chain that serves as their environment. The environment is driven linearly in time across its quantum critical points (QCPs) and, during the evolution, is subjected to quantum rese...
Spin-entanglement of an atomic pair through coupling to their thermal motion
Poramaporn Ruksasakchai, Lucile Sanchez, Marvin Weyland +3 more·Feb 10, 2026
The spin-dynamics of two alkali atoms in an optical tweezer is driven by spin-changing collisions that couple the spin-state of the atoms to their relative motion. This paper experimentally studies the resulting spin-states when the relative motion i...
Architectural Foundations for Checkpointing and Restoration in Quantum HPC Systems
Qiang Guan, Qinglei Cao, Xiaoyi Lu +1 more·Feb 10, 2026
In this work, we explore the design of the checkpointing and restoration for quantum HPC that leverages dynamic circuit technology to enable restartable and resilient quantum execution. Rather than attempting to checkpoint quantum states, our approac...
A Trainable-Embedding Quantum Physics-Informed Framework for Multi-Species Reaction-Diffusion Systems
Ban Q. Tran, Nahid Binandeh Dehaghani, A. Pedro Aguiar +2 more·Feb 10, 2026
Physics-informed neural networks (PINNs) and hybrid quantum-classical extensions provide a promising framework for solving partial differential equations (PDEs) by embedding physical laws directly into the learning process. In this work, we study emb...
High-performance Vector-length Agnostic Quantum Circuit Simulations on ARM Processors
Ruimin Shi, Gabin Schieffer, Pei-Hung Lin +3 more·Feb 10, 2026
ARM SVE and RISC-V RVV are emerging vector architectures in high-end processors that support vectorization of flexible vector length. In this work, we leverage an important workload for quantum computing, quantum state-vector simulations, to understa...
Raman Spectroscopic Investigation of Kitaev Quantum Spin Liquids
Vivek Kumar, Pradeep Kumar·Feb 10, 2026
Quantum spin liquids, a highly topologically entangled, dynamically correlated state where quantum fluctuations preclude any long-range ordering down to absolute zero. In the search for a topologically robust qubit, the scientific community has been ...
Accelerating Post-Quantum Cryptography via LLM-Driven Hardware-Software Co-Design
Yuchao Liao, Tosiron Adegbija, Roman L. Lysecky·Feb 10, 2026
Post-quantum cryptography (PQC) is crucial for securing data against emerging quantum threats. However, its algorithms are computationally complex and difficult to implement efficiently on hardware. In this paper, we explore the potential of Large La...
Time-marching representation based quantum algorithms for the Lattice Boltzmann model of the advection-diffusion equation
Yuan He, Yuanhong Yu, Yue Yu·Feb 10, 2026
This article introduces a novel framework for developing quantum algorithms for the Lattice Boltzmann Method (LBM) applied to the advection-diffusion equation. We formulate the collision-streaming evolution of the LBM as a compact time-marching schem...
LLM4PQC - Accurate and Efficient Synthesis of PQC Cores by Feedback-Driven LLMs
B. Perera, Zeng Wang, W. Xiao +4 more·Feb 10, 2026
The design of post-quantum cryptography (PQC) hardware is a complex and hierarchical process with many challenges. A primary bottleneck is the conversion of PQC reference codes from C to high-level synthesis (HLS) specifications, which requires exten...
QEMI: A Quantum Software Stacks Testing Framework via Equivalence Modulo Inputs
Junjie Luo, Shangzhou Xia, Fuyuan Zhang +1 more·Feb 10, 2026
As quantum algorithms and hardware continue to evolve, ensuring the correctness of the quantum software stack (QSS) has become increasingly important. However, testing QSSes remains challenging due to the oracle problem, i.e., the lack of a reliable ...
Quantum Multiple Rotation Averaging
Shuteng Wang, N. Meli, Michael Möller +1 more·Feb 10, 2026
Multiple rotation averaging (MRA) is a fundamental optimization problem in 3D vision and robotics that aims to recover globally consistent absolute rotations from noisy relative measurements. Established classical methods, such as L1-IRLS and Shonan,...
How to Classically Verify a Quantum Cat without Killing It
Yael Tauman Kalai, Dakshita Khurana, Justin Raizes·Feb 9, 2026
Existing protocols for classical verification of quantum computation (CVQC) consume the prover's witness state, requiring a new witness state for each invocation. Because QMA witnesses are not generally clonable, destroying the input witness means th...
The Quantum Many-Worlds Interpretation, Simply Told
Brian C. Odom·Feb 9, 2026
The many-worlds interpretation (MWI) of quantum mechanics poses a simple question. What would reality look like if everything evolved in time according to the same quantum equations? There is an attractive consistency to treating microscopic objects,...
