Quantum Computing Solutions (QCS) is a Valencia-based deeptech cybersecurity company that helps organisations move to post-quantum cryptography (PQC). Its core product is the Quantum Trusted Module (.qtm), an archival file format for the post-quantum era. It uses the NIST-approved Kyber and Dilithium algorithms, encrypted metadata and embedded usage policies to keep data confidential, authentic and auditable over the long term, including offline and air-gapped environments, without relying on external PKI. QCS also sells crypto-audit, quantum-secure backup and PQC training services to enterprises that must comply with NIS2, eIDAS2, ENS and DORA. It works with the Universitat Politècnica de València and S2 Grupo and takes part in ETSI standardisation work.
