Deterministic construction of arbitrary states with quadratically increasing number of two-qubit gates
arXiv:1606.09290 · doi:10.1063/5.0241266
Abstract
We propose a quantum circuit composed of gates and four single-qubit gates to generate a state of three qubits. This circuit was then enhanced by integrating two-qubit gates to create a state of four and five qubits. After a couple of enhancements, we show that an arbitrary state can be generated depending only on the degree of enhancement. The generalized formula for the number of two-qubit gates required is given, showing that an -qubit -state generation can be achieved with quadratically increasing number of two-qubit gates. Also, the practical feasibility is discussed regarding photon sources and various applications of gates.
