Rigetti and Riverlane Receive a 500 Thousand ($613K USD) Grant to Work on Error Correction

Rigetti Computing and Riverlane have received this grant from Innovate UK, the UKs national innovation agency, to study syndrome extraction on superconducting quantum computers. This would be a critical step for providing error correction on the qubits in a fault tolerant quantum computer. Since a qubit cannot be measured directly without collapsing quantum error correction circuits have to be made more complex than their classical counterparts. A common method is to include additional qubits in the circuit called ancilla (or auxiliary) qubits that can be entangled with the data qubits and subsequently measured to form a syndrome pattern. This syndrome pattern can indicate if there is an error within the data qubits and what qubits are affected. Additional gates can then be applied to the data qubits based upon the syndrom to fix the data qubits and correct the errors. The beauty of this approach is that while the ancilla qubits are measured the data qubits are not measured so they remain in the quantum state and dont collapse. This research from Rigetti and Riverlane will explore ways of implementing this error correction process while minimizing any additional errors that could result from the syndrome extraction process itself.
