A new hybrid platform for quantum simulation of magnetism

Simulating a quantum magnet in the hybrid approach

Having demonstrated accurate analog evolution, we then combined it with our more traditional specialty, high-precision digital gates, to study new physical phenomena. Leveraging our hybrid approach, we simulated a magnet, the behavior of which is very closely mimicked by the natural dynamics on our hardware. Each qubit can be thought of as a magnetic spin — think a little bar magnet — that interacts with its neighbors. We wanted to study what happens to the magnet when the interactions are turned on at varying rates, both because it is an interesting physics question that has attracted substantial attention in the field, and because it can improve our understanding of important techniques in quantum computing, such as quantum annealing.

To simulate this, we first used digital gates to initialize the qubits in an alternating pattern of 1s and 0s, representing spins pointing up and down, respectively. Then we ramped up the analog interactions between the spins at varying rates before switching back to digital mode for measurements. Intuitively, if the interactions are turned on very quickly, the magnetic spins are expected to not have time to react and remain stuck in their initial positions. If turned on slowly, on the other hand, they pull and twist on each other, as bar magnets do, and start pointing in the same direction. Indeed, we found that when the analog couplings were turned on very slowly, we were able to reach quantum states in which the spins align in the horizontal plane in a strongly correlated way, equivalent to a very low temperature. Importantly, here we are not referring to the temperature of the quantum chip itself (which is also very cold), but rather to that of the simulated magnet.

Interestingly, we reached sufficiently low temperatures to observe a famous phenomenon known as the Kosterlitz-Thouless transition, which is a sudden change in the degree of alignment of the magnetic spins in a material. Conceptually, this is similar to the way water molecules suddenly align when they freeze.

Highly correlated, low-temperature quantum states, such as those we observed, are the source of many fundamental puzzles in physics and were previously much less accessible with our purely digital scheme. Moreover, the hybrid approach allowed us to probe the transition in a versatile way, including the observation of several characteristic behaviors of the Kosterlitz-Thouless transition, which would not be possible in a purely analog simulation.

Cognigy Leads in Opus Research’s 2025 Conversational AI Intelliview

Published

on


Distinguished for Innovation, Enterprise Readiness, and Visionary Approach to Agentic AI

Cognigy, a global leader in AI-powered customer service solutions, has been recognized as the leader in the newly released 2025 Conversational AI Intelliview from Opus Research. The report, titled “Decision-Maker’s Guide to Self-Service & Enterprise Intelligent Assistants,” shows Cognigy as the leading platform across critical evaluation areas including product capability, enterprise fit, GenAI maturity, and deployment performance.

This recognition underscores Cognigy’s commitment to empowering enterprises with production-ready, scalable AI solutions that go far beyond chatbot basics. The report cites Cognigy’s strengths in visual AI agent orchestration, tool and function calling, AI Ops and observability, and a deep commitment to enterprise-grade control—all delivered through a platform built to scale real-time customer interactions across voice and digital channels.

“Cognigy exemplifies the next stage of conversational AI maturity,” said Ian Jacobs, VP & Lead Analyst at Opus Research. “Their agentic approach—combining real-time reasoning, orchestration, and observability—demonstrates how GenAI can move beyond experimentation into meaningful, measurable transformation in the contact center.”

Cognigy was one of the few vendors identified in the report as a “True Believer” in the evolution of GenAI-driven self-service, with tools designed to simplify deployment while giving enterprises full control. The platform’s AI Agent Manager enables businesses to create, configure, and continuously improve intelligent agents—defining persona, memory scope, and access to tools and knowledge—all through a flexible, low-code interface. Cognigy uniquely blends deterministic logic with generative capabilities, ensuring both speed and reliability in automation.

“This recognition from Opus Research is more than a milestone—it’s validation that our strategy is working,” said Alan Ranger, Vice President at Cognigy. “We’re delivering real-world, enterprise-grade automation that’s transforming contact centers. From financial services to healthcare to global retail, our customers are scaling faster, resolving issues in real time, and delivering truly modern service experiences.”

With global Fortune 500 customers and partnerships across the CCaaS and AI ecosystem, Cognigy continues to lead the way in delivering enterprise-ready AI that combines usability, speed, and impact. This latest industry acknowledgment further solidifies its position as the go-to platform for intelligent self-service.

Frontiers has announced that external fraud‑screening tools – Cactus Communications’ Paperpal Preflight, and Clear Skies’ Papermill Alarm and Oversight – have been integrated into its own Artificial Intelligence Review Assistant (AIRA) submission-screening system.

The expansion delivers what the companies describe as “an unprecedented, multilayered defence against organised research fraud, strengthening the reliability and integrity of every manuscript submitted to Frontiers”.

AIRA was launched in 2018, making Frontiers one of the early adopters of AI in submission checking. In 2022, Frontiers added its own papermill check to its comprehensive catalogue of AIRA checks, with the aim of tackling the industry-wide problem of manufactured manuscripts. The latest version, released in 2025, uses more than 15 data points and signals of potential manufactured manuscripts to be investigated and validated by a human expert.

Dr Elena Vicario, Head of Research Integrity at Frontiers, said: “Maintaining trust in the scholarly record demands constant innovation. By combining the unique strengths of Clear Skies and Cactus with our own AI capabilities, we are raising the bar for integrity screening and giving editors and reviewers the confidence that every submission has been rigorously vetted.”

Commenting on the importance of the partnership, Nikesh Gosalia, President, Global Academic and Publisher Relations at Cactus Communications, said: “This partnership with Frontiers reflects the confidence leading publishers have in our AI-driven solutions. Paperpal Preflight is a vital tool that supports editorial teams and existing homegrown solutions in identifying and addressing potential issues early in the publishing workflow.

“As one of the world’s largest and most impactful research publishers, Frontiers is taking an important step in strengthening research integrity, and we are proud to collaborate with them in this mission of safeguarding research.”

Adam Day, Founder and CEO of Clear Skies, added: “Clear Skies is thrilled to be working with the innovative team at Frontiers to integrate AIRA with Oversight. This integration makes our multi-award-winning services, including the Papermill Alarm, available across the Frontiers portfolio.

“Oversight is the first index of research integrity and recipient of the inaugural EPIC Award for integrity tools from the Society for Scholarly Publishing (SSP). As well as providing strategic Oversight to publishers, our detailed article reports support human Oversight of research integrity investigations on publications as well as journal submissions.”
