Problems solved by technology

[0002] In the existing quantum storage technology, the object usually stored is the number of photons. The main problem is that most of them store the number of photons, but they cannot effectively save the quantum state. There are methods for saving the quantum state. Various defects, such as the inability to freely modulate in three-dimensional space, the introduction of decoherence, the inability to delay modulation, and difficulty in integration, etc.

Embodiment Construction

[0024] like figure 1 As shown, it is a schematic diagram of the dynamic local phenomenon, which is similar to the phenomenon that the movement of electrons is suppressed in the periodic electric field. In the quantum field, it is observed that the evolution of quantum wave packets is suppressed or even completely stopped. The evolution in the linear sinusoidal bend waveguide is suppressed, and then the following quantum storage and delay modulation can be performed.

[0025] like figure 2 As shown, this embodiment relates to a photonic chip on-chip integrated delay modulation and complete quantum state wave packet storage implementation method based on a photonic dynamic localization, including the following steps:

[0026] Step 1) Determine the parameters of the bent waveguide according to the required conditions, specifically including: the spatial coordinates of the bent waveguide, the amplitude of 0.03mm, the period of 0.6cm, the total length of the bend 1.2cm, the numbe...

Abstract

The invention discloses an implementation method of an on-chip integrated delay modulation and quantum storage of a photon chip. A bending waveguide is designed and prepared in the photon chip through a femtosecond laser technology, evolution of photons in the bending waveguide is inhibited by using a dynamic local area phenomenon, and thus quantum storage and / or time-delay modulation are / is realized. The quantum state is effectively stored without introducing de-coherence through a dynamic local model of photons, and delay modulation and quantum storage can be realized in a three-dimensional space.

Description

technical field [0001] The invention relates to a technology in the field of quantum state storage, in particular to a method for realizing integrated delay modulation and quantum storage on a photon chip based on photon dynamic localization. Background technique [0002] In the existing quantum storage technology, the object usually stored is the number of photons. The main problem is that most of them store the number of photons, but they cannot effectively save the quantum state. There are methods for saving the quantum state. Various defects, such as the inability to freely modulate in three-dimensional space, the introduction of decoherence, the inability to delay modulation, and the difficulty of integration. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention proposes a method for implementing integrated delay modulation and quantum storage on a photonic chip, through which the dynamic local model of ...
