schedule_from_mid_cycle_circuit(circuit, layouts, gate_to_iterator, tick_iterators)[source]#

Returns the equivalent schedule from a stim circuit for contains mid cycle gates and/or codes.

Parameters:
circuit

Stim circuit.

layouts

List of layouts whose index match the qubit index in circuit. This function only works for layouts that only have one logical qubit.

gate_to_iterator

Dictionary mapping the names of stim circuit instructions used in circuit to the functions that generate the equivalent logical circuit. The value for TICK will be ommited as they should be specified in tick_iterators.

tick_iterators

Sequence of (half) QEC round iterators that are going to be used in cyclic order when encountering TICK instructions. Each iterator is applied to all the active layouts.

Returns:
schedule

List of operations to be applied to a single qubit or pair of qubits. See Notes for more information about the format.

Notes

The format of the schedule is the following. Each element of the list is an operation to be applied to the qubits: - tuple[LogOpCallable, Layout] performs a (logical) single-layout operation - tuple[LogOpCallable, Layout, Layout] performs a (logical) two-qubit gate.

For example, the following circuit

with tick_iterators = [to_mid_cycle_iterator, to_end_cycle_iterator] is translated to
