The invention discloses a quantum remote cloning method and system based on an integrated photon chip, and the method comprises the steps: dividing pump light into two paths, and respectively coupling the two paths to enter a transmitting end chip and a receiving end chip; idle photons and unknown quantum state photons to be cloned are generated in the sending end chip; photons C1, C2 and P are obtained in the receiving end chip, and the obtained photon P is coupled to the sending end chip; in a sending end chip, unitary transformation of phase adjustment or basis vector transformation is carried out on unknown quantum state photons to be cloned, X0 and X1 are obtained, and on-chip Bell state measurement is carried out on X0, X1 and P after X0 passes through a thermal modulation phase shifter; according to an on-chip Bell state measurement result, information of an unknown quantum state X to be cloned is non-locally distributed to photons C1 and C2 on a receiving end chip, and two optimal symmetric cloning states are obtained by taking the photons C1 and C2 on the offset receiving end chip.

This utility model provides a small roadbed filling and compaction device for operation in confined spaces, belonging to the field of compaction equipment technology. It includes a motor, a rotating shaft protective shell, a buffer shell, a compaction plate, a rotating rod, a hammer rod, and a connecting block. The rotating shaft protective shell has a set of circular holes on each of its upper two sides, and the motor's bottom connecting plates have a set of circular holes on each of their two sides. The motor's bottom connecting plates are fastened to the upper two sides of the rotating shaft protective shell by screws. The rotating shaft protective shell has a set of circular holes in the center of its top, and the rotating rod has a set of circular heads at its top. The rotating rod and hammer rod, along with a novel transmission device, allow for efficient up-and-down hammering and greater stability. An extended handle device is included, allowing access to the device without personnel by extending the handle in narrow or inaccessible locations or during certain working periods. Multiple buffer devices are incorporated to allow for rapid rebound after hammering, improving the efficiency of the telescopic operation.
