Abstract

Large-scale universal quantum computers are expected to vastly outperform classical computers in important applications. Small-scale machines already exist in university and industry labs today, but their usefulness is limited by size and performances, regardless of their underlying qubit technology.

Moving towards broad computational advantage means making quantum computers better as well as begger. At Oxford Ionics we do this by combining the precision of atomic ions – used for the most precise clocks in the known universe – with the scalability of microelectronics.

I will motivate why trapped ions make the best qubits, how we develop large-scale quantum computers at Oxford Ionics, and IonQ company, based on a small set of fundamental operations and simple guiding principles. I will show how this enables us to demonstrate the highest performance quantum gates to date, among all physical platforms.
