Quantum Elements' Constellation Helps Rigetti Model Its Quantum Chips

At a glance

Quantum computing company Rigetti is using Quantum Elements' Constellation platform to simulate how its quantum chips behave on a computer. The goal is to estimate how well the chips will perform at large scale before they are built.

Key points

1. 1

   Constellation creates virtual copies (digital twins) of real quantum chips that run on ordinary computers.

2. 2

   Rigetti says three years of work showed it can accurately predict the performance of one- and two-qubit operations on its 36-qubit and 108-qubit chips.

3. 3

   Constellation now supplies inputs for the noise models Rigetti uses in its quantum error correction (fixing errors during computation).

Why it matters

Reducing errors is central to making quantum computers practical, and simulations like this help find problems before chips are made.
