Merges connected components of operations, acting on <= k qubits, into circuit operations.

Uses cirq.merge_operations_to_circuit_op to identify and merge connected components of unitary operations acting on at-most k-qubits. Moment structure is preserved for operations that do not participate in merging. For merged operations, the newly created circuit operations are constructed by inserting operations using EARLIEST strategy.

circuit Input circuit to apply the transformations on. The input circuit is not mutated.
k Merge-able operations acting on <= k qubits are merged into a connected component.
tags_to_ignore Tagged operations marked any of tags_to_ignore will not be considered as potential candidates for any connected component.
merged_circuit_op_tag Tag to be applied on circuit operations wrapping valid connected components. A default tag is applied if left None.
deep If true, the transformer primitive will be recursively applied to all circuits wrapped inside circuit operations.

Copy of input circuit with valid connected components wrapped in tagged circuit operations.
