Noise-adapted recovery circuits for quantum error correction

2023 · arXiv (Cornell University)

Implementing quantum error correction (QEC) protocols is a challenging task in today's era of noisy intermediate-scale quantum devices. We present quantum circuits for a universal, noise-adapted recovery map, often referred to as the Petz map, …

Security of differential phase shift QKD against explicit individual attacks

2023 · arXiv (Cornell University)

Quantum key distribution (QKD) is known to be unconditionally secure in principle, but quantifying the security of QKD protocols from a practical standpoint continues to remain an important challenge. Here, we focus on phase-based QKD …
