We will look at the basics of quantum error correction, starting from the repetition code and then focusing on surface codes. Finally we’ll consider the outlook towards high-rate LDPC codes.
In digital communication, authentication, integrity, and confidentiality are fundamental security requirements. These properties enable robust security controls such as secure boot, secure update, secure access, and secure TLS across connected devices. However, existing cryptographic algorithms, while effective against classical threats, vulnerable to powerful quantum attacks. In this paper,...
Photonic quantum computing has recently emerged as a promising candidate for fault-tolerant quantum computing by photonic qubits. These protocols make use of nondeterministic gates, enabling universal quantum computation.
However, the suggested solutions heavily use particle number resolving detectors (PNRDs), which are experimentally hard to realize and are usually biased in practice. We...
