On the 14th, SK Telecom unveiled the 'Galaxy A Quantum,' a 5G smartphone equipped with a quantum random number generation chipset, in collaboration with Samsung Electronics. Priced at 649,000 won, it will be officially launched on the 22nd following pre-orders from May 15 to 21. The Galaxy A series is a product line in which Samsung Electronics showcases technologies that will be applied to flagship models such as the Galaxy S series or Galaxy Note series.
The Galaxy A Quantum is equipped with a 2.5×2.5mm Quantum Random Number Generator (QRNG) chipset. Inside the quantum random number generation chipset, a CMOS image sensor detects light (photons) emitted by an LED light source, and extracts random numbers using the quantum randomness that 'the number of photons detected within a certain sensor area over a certain period of time is unpredictable.'
The extracted random numbers are used as encryption keys for T ID dual login, SK Pay biometric authentication protection, and the blockchain mobile electronic certification service 'Initial'. All services undergo encryption and decryption processes when storing or exchanging data, and encryption keys are essential for this process.
When logging in with a T ID on the Galaxy A Quantum, users undergo a dual security process of '1st ID login → 2nd Quantum OTP authentication.' Quantum security-based OTP (One-Time Password) authentication is added to the existing ID login, providing safer protection for the user's account.
When making payments at offline merchants such as convenience stores and restaurants using the SK Pay app, previously stored biometric authentication information (fingerprints) is used, and this process is also protected by quantum security. SK Telecom is currently developing the application of quantum security to online merchant app payments as well in the future.
Initial is a personal certificate storage service that prevents forgery and tampering using blockchain DID (Decentralized Identifier) technology. When Galaxy A Quantum users save various personal certificates to Initial, a 'Quantum Wallet' is automatically created, allowing them to store them securely.
Existing quantum security technologies have so far been primarily applied to communication networks and servers. An SK Telecom official stated that the company plans to expand the related ecosystem so that quantum security can be applied to more services in the future. The company intends to support technology development by sharing open APIs for developers on the SK Open API website. In addition, we plan to continuously expand quantum security-based services in various areas such as 5G networks, IoT, autonomous driving, and cloud.
Gregoire Ribordy, CEO of IDQ, explained, “Quantum random number generation chipsets are ultra-compact, low-power products optimized for smartphones,” adding, “The launch of the Galaxy A Quantum is significant as it marks the first application of quantum security technology to the mass market.”

The Problem with AI is Not Performance, but Trust
CEO Kang Min-seung emphasized at Snowflake's World Tour Seoul that generative AI has entered a phase where "trust" rather than accuracy becomes the key competitive advantage. As AI is applied to various tasks including consultation, risk management, and operational automation, incorrect data, erroneous responses, and bias are creating actual business risks. He pointed out that enterprises must build a trust layer above AI. To achieve this, accurate data management, semantic structuring, governance, and prompt security are essential. He explained that AI is not merely an automation tool but a technology that reorganizes the entire organization's workflows and decision-making systems. Snowflake provides a platform that supports this trust-based AI operation, emphasizing that enterprises should build "trustworthy AI" rather than "intelligent AI."

The Decisive Factor for AI Agents in Finance: "Trustworthy Data Infrastructure"
The key to spreading AI agents in the financial sector is establishing a trustworthy data system. KB Kookmin Bank is operating over 100 AI agents by 2025 and is promoting expansion to 300. AI is automating repetitive tasks across various areas such as consultation, risk management, wealth management, and relationship management. However, if data quality, governance, and semantic structuring are insufficient, errors and risks increase. KB is building an AI-Ready organization through a multi-model strategy of GPT, Gemini, and Claude, as well as a Snowflake-based data system. The bank emphasized that AI has entered a phase where it restructures not just simple automation but the entire work process and decision-making system.
