The first line contains the number of qubits. The rest of the lines specify gates with one gate per line. The format for a gate is
time gate_name qubits parameters
Here time refers to when the gate is applied in the circuit. Gates with the same time can be
applied independently and they may be reordered for performance. Trailing
spaces or characters are not allowed. A number of sample circuits are provided
in circuits.

Gate times of the gates that act on the same qubits should be ordered. Gates that are out of time order should not cross the time boundaries set by measurement gates. Measurement gates with equal times get fused together.
