Aires is part of Singapore’s growing quantum-technology ecosystem, which benefits from a 2025 national R&D budget of about US$37 billion, alongside peers like Squareroot8 Technologies and Horizon Quantum.

Two Singaporean brothers, Lim Meng Liang and Ken Lin, founded Aires Applied Quantum Technology in 2023 after securing a US patent in 2022 for encrypting data with unsolvable Diophantine equations, aiming to forge unbreakable encryption resistant to quantum attacks.

Lim Meng Liang is a Singaporean mathematician who, with his brother, developed a new form of encryption based on Diophantine equations, and launched Aires after patenting the approach.

Skepticism from the brothers’ parents has given way to growing interest as potential clients seek practical timelines for implementing quantum-resistant security.

LionGuard is the flagship, a subscription-based mobile app that encrypts files across devices, cloud or networks using sender-generated keys, with a model aiming to withstand quantum computer threats.

Aires currently has eight employees focused on software development, marketing and operations, with plans to attract small and medium-sized enterprises across law, accounting, food and beverage, and family offices.

Organizations are increasingly asking about integration and deployment timelines, signaling a shift from theory to commercial viability of quantum-resistant cybersecurity.

Aires has raised over US$2 million and is exploring listings in the United States, Singapore, or Japan to fund global expansion, with beta users exceeding 100 enterprise subscribers.

The founders are pursuing an eight-digit funding round to market their product globally and have attracted over US$2 million in private investment, with local support from Enterprise Singapore.

LionGuard operates on a sender-generated key system where the recipient’s app unlocks the data, positioned for broader enterprise use with a monthly per-user fee.

Aires holds four international patents, including technology to secure QR codes and barcodes, and these are being piloted in Europe, with plans to reduce subscription fees to lure SMEs.

The company’s four international patents cover data encryption and securing 2D codes, and pilots in Europe are underway to validate the technology.
