mindquantum.algorithm.library.general_ghz_state

mindquantum.algorithm.library.general_ghz_state(qubits)

Circuit that prepare a general GHZ State based on zero state.

The GHZ State is defined as the equality superposition of three zeros state and three ones state:

$$|\text{GHZ}⟩=(|000⟩+|111⟩)/\sqrt{2}$$

Here in this API, we can create a general GHZ state on arbitrary sub qubits of any total qubits.

Parameters

qubits (list[int]) – Qubits you want to apply general GHZ state.

Returns

Circuit, circuit that can prepare ghz state.

Examples

>>> from mindquantum.algorithm.library import general_ghz_state
>>> print(general_ghz_state(range(3)).get_qs(ket=True))
√2/2¦000⟩
√2/2¦111⟩
>>> print(general_ghz_state([1, 2]).get_qs(ket=True))
√2/2¦000⟩
√2/2¦110⟩
