class Resources(num_wires=0, num_gates=0, gate_types=<factory>, gate_sizes=<factory>, depth=0, shots=<factory>)[source]

Bases: object

Contains attributes which store key resources such as number of gates, number of wires, shots, depth and gate types.

  • num_wires (int) – number of qubits

  • num_gates (int) – number of gates

  • gate_types (dict) – dictionary storing operation names (str) as keys and the number of times they are used in the circuit (int) as values

  • gate_sizes (dict) – dictionary storing the number of \(n\) qubit gates in the circuit as a key-value pair where \(n\) is the key and the number of occurances is the value

  • depth (int) – the depth of the circuit defined as the maximum number of non-parallel operations

  • shots (Shots) – number of samples to generate

The resources being tracked can be accessed as class attributes. Additionally, the Resources instance can be nicely displayed in the console.
