Quantum code space administration

A quantum computing system, comprising:

• first quantum hardware implementing a first plurality of qubits in a first quantum code space;
• second quantum hardware implementing a second plurality of qubits outside of the first quantum code space, wherein each qubit of the first plurality of qubits has a qubit fidelity that is higher than a qubit fidelity of each qubit of the second plurality of qubits;
• and
• one or more processor devices to:
• route, based at least in part on first data indicative of a first risk of quantum error associated with a first quantum process, a first portion of the first quantum process to the first quantum hardware;
• and
• route, based at least in part on second data indicative of a second risk of quantum error associated with the first quantum process, a second portion of the first quantum process to the second quantum hardware.

A non-transitory computer-readable storage medium that includes executable instructions to cause one or more processor devices to:

• obtain first data indicative of a first risk of quantum error associated with a first quantum process;
• route, based at least in part on the first data, a first portion of the first quantum process to first quantum hardware implementing a first plurality of qubits in a first quantum code space;
• obtain second data indicative of a second risk of quantum error associated with the first quantum process;
• and
• route, based at least in part on the second data, a second portion of the first quantum process to second quantum hardware implementing a second plurality of qubits outside of the first quantum code space, wherein each qubit of the first plurality of qubits has a qubit fidelity that is higher than a qubit fidelity of each qubit of the second plurality of qubits.
