Singapore’s Aires Applied Quantum Technology (AAT) is making strides in the quantum technology sector by advancing Southeast Asia’s first internationally filed post-quantum cryptography (PQC) and quantum technology patents. Founded and developed entirely in Singapore, AAT is one of the few deep-tech start-ups in the region approaching commercial viability, with a focus on encryption, IoT security, and quantum simulation algorithms.
AAT’s innovations are supported by a local research team and have garnered recognition from agencies such as Enterprise Singapore and the Monetary Authority of Singapore. The company’s patented technologies are designed to facilitate the adoption of quantum-safe cryptography by enterprises and individual users across Asia. Their offerings include quantum-resistant encryption APIs and the consumer app LionGuard, which provides quantum-safe cryptography on multiple platforms.
Ken Lin, Co-founder and Managing Director at AAT, highlighted the shift towards an IP-driven model in the quantum sector. “Recent patent consolidations by leading global firms underline how quickly proprietary algorithms and in-house research are becoming the core determinants of value,” he stated.
AAT’s approach focuses on lean algorithmic development, allowing it to operate profitably whilst expanding its patent portfolio and international partnerships. The company is exploring global expansion opportunities as Singapore continues to strengthen its quantum ecosystem.
As Singapore aims to secure its digital infrastructure and enhance economic competitiveness, AAT’s development underscores the importance of local innovation in building a diverse and resilient quantum ecosystem. The presence of homegrown firms like AAT is crucial for helping businesses adopt quantum-safe practices as quantum hardware becomes more accessible.
