API

• boot(qubitRegsNum, classicRegNum=qubitRegsNum) init quantum computing circuit.
• applySingleBitMatrix(offset, matrix) apply matrix to qubitsoffset.
• applyTwoBitsMatrix(control, target, matrix) apply matrix to qubitscontrol and qubitstarget.
• id(offset || 'all') apply Identity Gate to qubitsoffset or all qubits.
• x(offset || 'all') apply Pauli X Gate to qubitsoffset or all qubits.
• y(offset || 'all') apply Pauli Y Gate to qubitsoffset or all qubits.
• z(offset || 'all') apply Pauli Z Gate to qubitsoffset or all qubits.
