Quantum computers are expected to become capable of breaking the cryptographic algorithms that secure the world’s digital infrastructure within the next decade. Yet, while awareness of the so-called “Q-Day” is high, many enterprises remain unprepared to mitigate that risk.

According to the newly released 2026 Global state of post-quantum and cryptographic security trends study by Entrust and the Ponemon Institute, nearly half (49%) of Singapore cyber security leaders believe a quantum computer capable of breaking Rivest-Shamir-Adleman (RSA) and elliptic-curve cryptography (ECC) encryption will emerge within just five years.

Despite this, just a third of organisations in Singapore are actively preparing to transition to
