This tag refers to public-key algorithms based on problems that quantum computers can't solve efficiently. Existing algorithms such as RSA, Diffie-Hellman, and ECDSA are known to be breakable using Shor's algorithm on quantum computers. Symmetric-key algorithms generally don't fall under this category.

LWE: Round a continuous Gaussian to a true Discrete Gaussian
Short version: how is it possible to round a continuous Gaussian into a true discrete Gaussian (usually denoted $\mathcal{D}_{\mathbb{Z},\alpha q}$)? The goal is to obtain a reduction from continuous …
