Building a Reliable Quantum Computer
38:26 - 47:12 (08:46)
Decoherence is the unwanted interaction between qubits and the external environment when building a quantum computer. However, to build a reliable quantum computer with an arbitrary number of qubits, they do not have to be perfectly isolated from the external environment.

Engineers have been working on building qubits that are reliable enough to use error-correcting codes to simulate even more reliable qubits.

Summary
Engineers have been working on building qubits that are reliable enough to use error-correcting codes to simulate even more reliable qubits. However, recent research suggests that even if the qubits are not perfectly reliable, encoding information cleverly across the collective states of multiple qubits can lead to arbitrarily reliable qubits.
