Quantum Computation with Light

Optical devices are among the most used and widespread technologies currently employed to perform quantum computations and quantum information processing tasks. They are usually cheaper than other implementations and are natural candidates for realizing communications protocols: Once a photonic state is … Continue reading

Why we should be talking about the ethics of quantum computation

Gyges was a shepherd in the service of the king of Lydia; there was a great storm, and an earthquake made an opening in the earth at the place where he was feeding his flock. Amazed at the sight, he … Continue reading

Tools for Drawing Quantum Circuits

Last night I was writing an article for the series “The more You Know” to add to my Dictionary of Quantum Information and Quantum Computation and I ran across the need to draw a Quantum Circuit. Although my first thought was … Continue reading

The More You Know: Quantum Circuit

Quantum Circuits are used to visualize a prescription of quantum gates acting on a quantum state. They describe the changes of the quantum data as it undergoes successive discrete operations. The data in a Quantum Circuit is usually encoded in a -qubit state (other Quantum Circuit … Continue reading
