The ACM Conference on Post-Quantum and Quantum-based Security (PQQS) is a premier forum dedicated to research at the intersection of cybersecurity and quantum technologies. The conference covers both quantum-enabled security systems and post-quantum cryptographic migration, integrating theory, systems, deployment, and standardization perspectives. We invite submissions describing original research contributions, experience reports, and system artifacts relevant to post-quantum and quantum-based security.

Topics of interest include, but are not limited to:

Post-Quantum Cryptography (PQC)

Algorithmic foundations: lattice-based, code-based, multivariate, hash-based, isogeny-based constructions
Security proofs and cryptanalysis of PQC schemes
Post-quantum key exchange, signatures, and authenticated encryption
Implementation security, side-channel resistance, and fault attacks
Hybrid cryptographic protocols and backward compatibility
Performance evaluation and optimization
Secure deployment in networks, cloud, IoT, cellular systems, and critical infrastructure
Migration strategies and cryptographic agility
Threat modeling under harvest-now-decrypt-later adversaries
Standardization and compliance (e.g., NIST PQC transition)

Quantum-Based Security

Quantum key distribution (QKD) and quantum communication networks
Security of quantum devices and hardware implementations
Security of quantum compilers and quantum cloud platforms
Verification and formal models for quantum protocols
Quantum-secure network architectures
Quantum randomness generation and certification
Side-channel and implementation attacks on quantum systems
Integration of classical and quantum cryptographic infrastructures

Systems and Infrastructure Security in the Quantum Era

Secure migration of large-scale distributed systems
Post-quantum security in 5G/6G, edge, and satellite networks
Quantum-safe PKI and identity management
Blockchain and distributed ledger security in a post-quantum world
Secure firmware, hardware accelerators, and trusted execution under PQ assumptions
Cloud and data center cryptographic transition
