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 ...

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,...
