摘要：
Various quantum algorithms depend on quantum phase estimation (QPE) as basic blocks or main subroutines to leverage superposition and entanglement during quantum computations. The QPE algorithm estimates the unknown phase of an eigenvalue corresponding to an eigenstate of an arbitrary unitary operator. We propose the photonic scheme of a QPE scheme comprising controlled-unitary gates based on quantum dots confined in optical cavities. For the reliable performance of the proposed QPE scheme constituting an arrangement of controlled-unitary gates, we evaluate the proposed quantum dot system under the effects of vacuum noise and leaky modes in an experimental implementation of the gates.
