On the Energy Costs of Post-Quantum KEMs in TLS-based Low-Power Secure IoT

2021

Recent achievements in designing quantum computers place a serious threat on the security of state-of-the-art public key cryptography and on all communication that relies on it. Meanwhile, security is seen as one of the most …

No Scratch Quantum Computing by Reducing Qubit Overhead for Efficient Arithmetics

2025 · arXiv (Cornell University)

Quantum arithmetic computation requires a substantial number of scratch qubits to stay reversible. These operations necessitate qubit and gate resources equivalent to those needed for the larger of the input or output registers due to …
