An Intro to Quantum Mechanics; Google’s Claim to Quantum Supremacy

by

The science that deals with the description of the motion and interaction of subatomic particles is known as Quantum Mechanics. Traditional computers utilize the physics of electricity, the flow of electrons controlled by switches, to control their logic. Quantum computers rely instead on the physical properties of electrons, photons, and other tiny bits of matter … Read more An Intro to Quantum Mechanics; Google’s Claim to Quantum Supremacy

Quantum Programming 101: Superdense Coding Tutorial

by

By Macauley Coggins What is Superdense coding ? Superdense coding is a quantum communications protocol that allows a user to send 2 classical bits by sending only 1 qubit. The Protocol Step 1: Preparing the Bell Pair First a bell pair consisting of 2 qubits is prepared. Where q0 is the senders qubit and q1 … Read more Quantum Programming 101: Superdense Coding Tutorial

(Very) Basic Intro to Lattices in Cryptography

by

By Lane Wagner – @wagslane on Twitter Lattice-based cryptography has been coming into the spotlight recently. In January 2019, Many of the semifinalists in the NIST post-quantum-cryptography competition were based on lattices. Let’s explore the basics of lattices and how they apply to cryptosystems. What is a Lattice? According to Wikipedia, a lattice is the set of … Read more (Very) Basic Intro to Lattices in Cryptography
