# Physicists Extend Qubit Lifespan in Pivotal Validation of Quantum Computing

### Did Quantum Error Correction just have a breakthrough?

On Science alert and other publications there’s the promise of a “Quantum breakthrough” pretty much every other week. I think in 2023 we are at the point where we can make significant steps towards improved Quantum Error Correction.

Quantum error correction **protects information by encoding it across multiple physical qubits to form a “logical qubit,”** and is believed to be the only way to produce a large-scale quantum computer with error rates low enough for useful calculations.

In a new experiment, scientists were able to keep a qubit in that state for twice as long as normal. What is Quantum Error Correction? (Wiki). What is Quantum Error Correction read: by Q-CTRL.

So while Amazon chases Quantum networks with artificial diamonds, this Yale announcement has peaked my interest.
