QiT: Quantum-Inspired Transformer for Visual Recognition Task

QT is introduced, a Quantum-inspired Transformer for vision tasks with three components: angle-inspired encoding that maps image tokens to learned trigonometric Hilbert-space features analogous to quantum rotation-based state encoding; self-attention over these periodic features, inducing a classical cosine kernel appr...

$\mathcal{O}(n)$ alternative to Quantum Fourier Transform with efficient neural net classical post-processing

A family of shallow circuits using Hadamards and controlled-Phase gates, HP-$L$ circuits, are constructed that prove preserve shift invariance and the $\mathcal{O}(n)$ HP-$1$ QFT in the numerical implementation of Shor's algorithm.

Shuttling Compiler for Trapped-Ion Quantum Computers Based on Fine-Tuned Large Language Models

In trapped-ion quantum computers, qubits must be shuttled between segments to interact. The routing logic that schedules these movements is written by hand for every new trap architecture. We present shuttling compilers based on five large language models (LLMs). Each LLM is fine-tuned on shuttling schedules produced b...

Training Energy-Based Models with Non-MCMC Samplers and Efficient Temperature Estimation

Efficient sampling from Boltzmann distributions over discrete variables is a fundamental operation in a wide range of applications. While fast non-MCMC samplers have recently emerged as promising alternatives to conventional MCMC methods, their practical use for probabilistic learning remains hindered by the difficulty...

Towards Surrogate Based Dequantization of Quantum Reinforcement Learning

In recent years, the utility of parameterized quantum circuits as function approximators has been widely studied. In the context of reinforcement learning, this approach has led to variational quantum algorithms such as quantum Q-learning. While these methods show promising empirical results, and can provide provable a...

Parameter-Efficient Quantum NLP for Paraphrase Detection: Performance, Robustness, and Entanglement

Rigorous empirical validation of quantum machine learning on natural language tasks remains scarce. We evaluate a 10-qubit hybrid quantum-classical variational circuit (2,148 parameters) for paraphrase detection across three benchmarks: MRPC, Quora Question Pairs (QQP), and adversarial PAWS. On QQP (n = 10 seeds), the...

Scaling Hindi Quantum Natural Language Processing through Automatic Pregroup Supertagging

Automatic Hindi pregroup assignment is feasible and can reduce reliance on manual annotation in future multilingual QNLP pipelines, and suffix/morphology features improve karaka-token accuracy but not overall performance.

What resources are needed for optimal learning of bosonic Gaussian states?

Continuous-variable systems enable key quantum technologies in computation, communication, and sensing. Bosonic Gaussian states emerge naturally in various such applications, including gravitational-wave and dark-matter detection. A fundamental question is how to characterize an unknown bosonic Gaussian state from as f...

Exact Spin Elimination for Quadratic and k-Local Ising Optimization

These results establish exact spin elimination as a controlled trade between active-spin capacity and interaction complexity and show that removing spins while allowing more complex interactions can fit larger problems within the same spin budget and improve optimization.

Certification cost of quantum models: measurement correlation, not parameter count

Reporting the Fisher geometry of a trained variational quantum model is routine; quoting the shot budget that would establish it is not. Certifying an empirical Fisher matrix to relative Frobenius error $\varepsilon$ under coordinate-wise parameter shift costs $\Theta(B p^{2} V/(\varepsilon^{2} G))$ circuit executions,...

Conditional Quantum Flow Matching for Data-Scarce Physiological Signal Augmentation

Generative augmentation is a standard remedy for label scarcity in physiological signal classification, but existing quantum generative models start from uninformative noise, ignoring class structure that is already available. We propose Conditional Quantum Flow Matching (CQFM): a single 306-parameter circuit, conditio...

What AI gets wrong and what failure teaches us

Jennifer Neville did not want to go into computer science—but that’s exactly where she landed. Neville discusses the starts and stops that led to her professional sweet spot and her work identifying “surprising failures” making it hard for AI to handle complexity.  The post What AI gets wrong and what failure teaches us appeared first on Microsoft Research.

Introducing Quine: An AI research system designed for the complexity of biology

Biology doesn't operate in silos, and neither should the AI representation of it. Quine is an early-stage research effort to create a multimodal world model of biology. By connecting insights across biological scales and modalities, Quine helps scientists computationally search a space far larger than intuition allows and prioritize hypotheses before they reach the lab. Experimental results provide important feedback, helping researchers sharpen future research directions. The post Introducing Q…
