Quantum in Numbers
Qubits and their Quality
share this graphic
A current challenge in quantum industry is reducing errors while at the same time increasing the number of qubits
Two-qubit gates in particular need to have low error rates in order for the quantum device to perform useful tasks.
Above, we compare the number of qubits against the average two-qubit gate error rates for different devices.
Error Correction

Engineering quantum error correction codes reaching beyond break-even is an important step towards fault-tolerant quantum computing
The graphic above compares the bare qubit lifetime against the error-corrected logical qubit.
