Published

on

NEW DELHI, April 19, 2025 /PRNewswire/ — In an era where cybersecurity challenges continue to grow, Synergy Quantum is once again pushing the boundaries of quantum technology. Building on its expertise in quantum encryption, our team is developing an innovative method to test the limits of Quantum Key Distribution (QKD) using a quantum switch. This groundbreaking approach is set to expose potential vulnerabilities in QKD systems, a core component of next-generation encryption. By harnessing the power of indefinite causal order, the team is working on creating an attack model that can manipulate quantum communication without triggering traditional security defences. With this cutting-edge research, Synergy Quantum is not only advancing the understanding of quantum security but also paving the way for the development of stronger, more resilient encryption protocols to protect against the evolving threats of tomorrow.

In an exciting new development, researchers at Synergy Quantum are embarking on a pioneering experiment to challenge the security of quantum encryption systems. The team is preparing to implement a cutting-edge quantum switch within a Sagnac loop architecture, which could potentially expose vulnerabilities in Quantum Key Distribution (QKD) protocols.

” This is an exciting moment for our team and the field of quantum cryptography,” said Mr. Jay Oberoi, Founder & CEO, Synergy Quantum, ” We ‘re taking a bold step towards implementing and addressing the unseen risks in quantum communication. The success of this project could redefine how we approach the security of the next generation of encryption technologies.”

The groundbreaking idea behind breaking QKD using a quantum switch is reported by Prof. Arun K Pati  and his collaborators Dr Sumit Nandi, Biswaranjan Panda and Prof. Pankaj Agrawal which appeared in a recent paper [Breaking Quantum Key Distributions under Quantum Switch-Based Attack, arXiv:2502.06780 (2025)]. “The concept of exploiting quantum superposition of causal order in the context of QKD security is a natural progression in quantum research,” said Professor Pati.  Dr Nandi and Panda said, “By manipulating the order of quantum operations, we aim to test the very foundations of quantum encryption and reveal hidden vulnerabilities that have remained unnoticed.”

As part of its pioneering efforts in quantum security, Synergy Quantum is currently working on an innovative and ambitious project to practically develop a Quantum Switch capable of breaking QKD systems. This initiative is being driven by Prof. Arun K Pati, Director R&D, Synergy Quantum.  Here, our vision is to explore the potential of indefinite causal order in quantum key distribution systems. Dr. Gautam, Director QKD, Synergy Quantum , the project lead for the experimental implementation, has taken the next crucial step—bringing Professor Pati’s theoretical idea into a working model. “Building a quantum switch that can perform this level of interference and then testing it within a real-world QKD system is the true challenge,” said Dr. Gautam. “This experiment will help us understand the practical implications of such an attack, opening up new areas of research for quantum security and the development of stronger encryption methods.”

The team is poised to integrate the quantum switch into a BB84 QKD testbed, where it will be used to perform an intercept-and-resend attack while minimizing the Quantum Bit Error Rate (QBER) and evading traditional detection methods. This proof-of-concept experiment is expected to shed light on vulnerabilities in current QKD systems, highlighting the need for the development of new security measures to ensure the long-term protection of quantum communications.

The Finish Line that Changed China: Retracing the Long March to Yan’an

Published

on

By

BEIJING, July 23, 2026 /PRNewswire/ — A news report from China.org.cn on the Long March, and what it means for China today:

 

Every journey has a destination.

But some destinations become the beginning of something even greater.

This is Yan’an.

Over 90 years ago, an army of soldiers embarked from Yudu, Jiangxi Province, on a journey that would go down in history.

They crossed snow-capped mountains, vast grasslands and raging rivers, eventually arriving in northern Shaanxi.

Across this grueling 12,500-kilometer journey, they wrote a magnificent epic in human history with willpower and courage.

Here, their Long March came to a victorious end. But a new chapter of history was only beginning.

In Yan’an, the Red Army found time to recover and rebuild, and the Central Committee of the Communist Party of China regrouped, gathering strength for the next chapter.

Here, new ideas were debated, new strategies were shaped, and a vision for China’s future gradually took form.

Today, while preserving its revolutionary legacy, Yan’an has grown into a vibrant, modern city — with a greener environment, thriving industries and happier lives for its people.

Nearly 90 years ago, American journalist Edgar Snow came to northern Shaanxi, seeking to uncover a story that few outside China knew. He later chronicled it in his book “Red Star Over China,” which carried the story of the Long March to the world.

Today, people from around the world are once again retracing those steps.

As part of China International Communications Group (CICG)’s “Together on the Long March” international communication project, participants have spent more than a month retracing the route across six key regions.

From Jiangxi to Shaanxi, they followed the Red Army’s journey and witnessed the remarkable changes that have taken place along the way.

I asked them one simple question: What does this journey mean to you?

Zhavier Harris, marketing and communications manager at the Springfield Urban League, said conversations with local residents and descendants of the Red Army made history feel far more immediate than he had expected.

He said history isn’t as distant as we often think. “We’re only one or two generations from these great sacrifices that led to the development and the greatness that we see from the Communist Party of China and China as a whole.”

David Ferguson, honorary chief English editor at Foreign Languages Press under CICG and a recipient of the 2021 Chinese Government Friendship Award, said the journey deepened his understanding of the Long March.

He said the journey helped him understand not only the historical facts, but also what the Red Army endured. “If you see the Long March merely as a military campaign, it ended in Yan’an. But as a spirit, it has never truly come to an end.”

We came to retrace history. We leave with something more: a deeper understanding of China’s past, a clearer view of its present, and perhaps a greater appreciation for the stories that connect us across cultures.

Edgar Snow called the Long March “an Odyssey unequalled in modern times.” He believed that what sustained it was a flame — consisting of an undimmed ardor, an undying hope and an amazing revolutionary optimism.

Ninety years later, that flame still burns.

Passed down through generations, the spirit of the Long March continues to light China’s path forward.

And as it crosses borders and cultures, it offers the world a glimpse of a nation defined by resilience, perseverance and an enduring drive to move forward.

Small and medium sized businesses (SMBs) often lack dedicated procurement teams and spend valuable time sourcing, purchasing and making payments themselves. In the transaction, the LoopXPay agent was used to source a product sample from a supplier and complete the purchase in a single workflow. The agent identified the purchasing requirement, recommended suitable suppliers, compared options, placed the order and securely executed the payment within a single workflow, while operating within pre-defined spending controls and approval parameters.

The milestone highlights how AI-powered commerce experiences can help SMBs simplify purchasing and payment activities while maintaining appropriate controls and oversight. By enabling AI agents to operate within pre-defined spending parameters and approval controls, businesses can reduce manual effort while retaining visibility into commercial decision-making.

As AI agents become more involved in purchasing and payment activities, businesses will require confidence that transactions are being executed by verified participants, within approved parameters and with appropriate oversight. Capabilities aligned with Visa’s Trusted Agent Protocol can help provide the identity, transparency and controls needed to support these interactions.

As part of the collaboration, LoopXPay has been registered in Visa’s Agentic Directory, enabling participating businesses and merchants to identify verified AI agents within the ecosystem. Supporting the implementation of Visa’s Trusted Agent Protocol, the Agentic Directory helps provide greater transparency into agent-driven interactions and confidence that participating agents have met Visa’s requirements.

“AI-powered commerce experiences can help businesses simplify purchasing and payments while maintaining the controls and oversight they require,” said Darren Parslow, Global Head, Visa Commercial Solutions, Visa. “For SMBs, that means less complexity in managing day-to-day commercial activities and more time focused on growth. As businesses increasingly look to embed intelligence into purchasing and payment experiences, trust will become a critical enabler of adoption. Through our collaboration with Lianlian, we are helping advance the trusted foundations that businesses will need to participate in this next era of commerce with confidence.”

Building on this milestone, Visa and Lianlian are exploring how AI agents can support a broader range of commercial activities, including procurement, digital advertising optimisation and B2B platform payments, helping advance trusted commerce through greater efficiency, transparency and control.

Zhang Zhengyu, Founder, Chairman of the Board and CEO, Lianlian DigiTech, said, “AI is reshaping the entire commercial value chain, where a growing number of business activities will be autonomously executed by AI agents, with payments serving as the critical infrastructure connecting them to global commerce. Leveraging its experience in global cross-border payments, compliance, as well as payment network, LianLian is actively building AI-native financial infrastructure, delivering an integrated suite of capabilities for the Agent Economy, spanning identity verification, transaction authorisation, intelligent payment, and global fund settlement.
