QBugLM: An Agentic Benchmarking Framework for LLM-based Quantum Software Debugging
Announce Type: new Abstract: Quantum software bugs often yield silent, incorrect outputs rather than explicit errors, making them particularly difficult to detect and repair with conventional techniques. Although large language models (LLMs) have shown strong performance on classical software engineering tasks, their ability to debug quantum code remains largely unexplored. To bridge this gap, we propose QBugLM, a multi-agent framework that automates the quantum software debugging pipeline,...
Detecting Flakiness in Quantum Software: A Dynamic Testing Approach
Announce Type: replace Abstract: Flaky tests, tests that pass or fail nondeterministically without changes to code or environment, pose a serious threat to software reliability. While classical software engineering has developed a rich body of techniques to study flakiness, corresponding evidence for quantum software remains limited. Prior work relies mainly on static analysis or small sets of manually reported incidents, leaving open questions about their prevalence, characteristics, and...
SoK: Post-Quantum Cryptography (PQC) Implementation in Software Systems
arXiv:2606.04669v1 Announce Type: new Abstract: The transition to Post-Quantum Cryptography (PQC) is essential to protect software systems from emerging quantum-enabled threats. Although standardised PQC algorithms are now available, developers and organisations continue to face significant challenges in integrating them into real-world software systems. While existing studies primarily focus on cryptographic performance and algorithmic security, it provides limited understanding of the...
Honeywell's Quantinuum heads for Nasdaq debut as quantum computing gains momentum
Honeywell's Quantinuum heads for Nasdaq debut as quantum computing gains momentum June 4 : Honeywell's Quantinuum is set to make its U.S. market debut later on Thursday, after strong investor interest helped the quantum computing company raise $1.68 billion in an upsized initial public offering. Breakthroughs in the fast-growing technology have spurred bets that quantum machines could eventually outperform conventional computers on certain complex tasks. Sentiment was also buoyed after the...
Honeywell's Quantinuum set to open higher in Nasdaq debut after upsized IPO
Honeywell's Quantinuum set to open higher in Nasdaq debut after upsized IPO June 4 : Shares of Honeywell-backed Quantinuum were indicated to open 1.67 per cent above their initial public offering price in their Nasdaq debut on Thursday, giving the quantum computing company a potential valuation of about $15.82 billion. The stock was last indicated to trade at $61, compared with its IPO price of $60. Breakthroughs in the fast-growing technology have spurred bets that quantum machines could...
Cloud-tested quantum noise model predicts superconducting qubit errors with sevenfold better accuracy
Cloud-tested quantum noise model predicts superconducting qubit errors with sevenfold better accuracy Gaby Clark Scientific Editor Robert Egan Associate Editor Researchers from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Johns Hopkins University in Baltimore have developed a practical, comprehensive noise-modeling framework for a popular class of superconducting quantum processors. Their work, published in the journal PRX Quantum, offers a sevenfold...
Microsoft’s next-gen quantum chip cuts timeline to useful quantum computing
Microsoft’s new Majorana 2 quantum chip. Microsoft Microsoft claimed last year that it had made a key breakthrough in quantum computing with Majorana 1, the company's first quantum processor. While physicists were immediately skeptical of Microsoft's claims, the software giant is announcing Majorana 2 today, the next generation of its topological quantum chip.
Quantinuum stock opens at $68 per share after IPO
Quantinuum opened trading at $68 per share on the Nasdaq on Thursday, after upsizing its initial offering. The company raised $1.68 billion in an upsized IPO after it priced at $60 per share, above its earlier range of $53 to $55 per share. At the first trade price, Quantinuum has a market cap of about $17.6 billion.
Entanglement Builds Space-Time. Now "Magic" Gives It Gravity
Entanglement Builds Space-Time. Now “Magic” Gives It Gravity. In 1973, John Archibald Wheeler described the relationship between space and matter in two sentences: “Space acts on matter, telling it how to move.
Empirical Evaluation of Large Language Models for Migration of Code Fragments to Post-Quantum Cryptography
arXiv:2606.07341v1 Announce Type: new Abstract: The transition to post-quantum cryptography (PQC) requires not only replacing vulnerable cryptographic primitives, but also refactoring the surrounding software logic. While existing PQC migration frameworks provide organizational guidance, practical code-level remediation remains largely manual and error-prone. This paper evaluates whether large language models (LLMs) can be trained to assist in the migration of pre-quantum cryptographic code...
