gav_quantum

gav_quantum is a quantum information utility package developed by Emil Marinov and Gray Alien Ventures.

Installation

pip install gav_quantum

Objects

ZERO - A column vector representation of the 0-state, [1 0]^T.

ONE - A column vector representation of the 1-state, [0 1]^T.

X, Y, Z - Standard X, Y, and Z Pauli operators.

PAULIS - An array of the Pauli operators in standard quantum information convention. Convenient for enumerations.

BELL_STATES[PHI_PLUS | PHI_MINUS | PSI_PLUS | PSI_MINUS] - The four maximally entangled Bell states.

Functions

W(N)

Inputs

• N - The number of qubits in the quantum state.

Output

• A vector corresponding to the maximally entangled N-qubit W-state.

GHZ(N)

Inputs

• N - The number of qubits in the quantum state.

Output

• A vector corresponding to the maximally entangled N-qubit GHZ-state.

operator_from_sparse_pauli(N, nonidentities)

Inputs

• N - The number of qubits in the quantum state.
• nonidentities - List of tuples specifying qubit number (indexed at 0) in ascending order and corresponding Pauli operator. Example: [(0,X),(2,'Y')]

Output

• A 2^N by 2^N operator.
