Physics and Astronomy Colloquium

Fault-tolerant quantum computation in the 21st century

Presented by Daniel Gottesman Perimeter Institute Fellow

Experimentalists are getting better and better at building
qubits, but no matter how hard they try, their qubits will never be
perfect. In order to build a large quantum computer, we will almost
certainly need to encode the qubits using quantum error-correcting
codes and encode the quantum circuits using fault-tolerant protocols.
This will eventually allow reliable quantum computation even when the
individual components are imperfect. I will review the current state
of the art of quantum fault tolerance and discuss progress towards
answering the most important questions that will enable large
fault-tolerant quantum computers.
