[0046] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0047] The present invention provides a laser optical path component based on 3D laser printing, which pre-designs the laser optical path of an ion trap quantum computer and solidifies the designed laser optical path into a resin component through a 3D laser printing process. In this way, during use, only the corresponding optical element needs to be inserted into the corresponding position of the component, avoiding the problem of unstable optical path caused by the installation of frames, lenses and screws during the installation process, and reducing the calibration requirements.

[0048] like Figure 1-12 As shown, the present invention provides a preferred embodiment, a laser optical path component based on 3D laser printing, comprising a first component body, an ionization light component mounting groove, a pump light component mounting groove, a detection light component mounting groove and a cooling light component mounting groove arranged in the first component body. Among them, the ionization light component mounting groove, the pump light component mounting groove, the detection light component mounting groove and the cooling light component mounting groove are used to install the ionization light component, the pump light component, the detection light component and the cooling light component, respectively.

[0049] Preferably, the ionizing light component is used to generate an ionizing light signal according to the light signal input to the first component body, and then output the ionizing light signal to the ion trap quantum computer to ionize the outermost electrons of the ytterbium atoms of the ion trap quantum computer to obtain stable ytterbium atoms.

[0050] The pump light component is used to generate a pump light signal so as to initialize the ions in the quantum state of the ion trap quantum computer at the beginning of the ion trap quantum computer experiment.

[0051] The detection light component is used to generate a detection light signal. The detection light signal is a laser signal used to detect the state of the ion trap quantum computer. State detection is performed after the quantum operation of the ion trap quantum computer is completed, and it is an important step in determining the fidelity of the quantum operation.

[0052] Cooling light components are used to generate cooling light signals. After the two-photon ionization process of the ion trap quantum computer is completed, the ytterbium atoms still have a speed of about several hundred meters per second. Once the ytterbium atoms are bound by the surrounding electric field in the trap, Doppler cooling is needed to slow down the ions and reduce the temperature of the ions. The principle of Doppler cooling is to use the collision of photons and ions to give the ions a momentum in the opposite direction, so that the ions slow down; at the same time, when an ion absorbs a photon, it will release a photon in all directions due to spontaneous radiation. The spontaneous radiation process is isotropic, and the recoil caused by spontaneous radiation can also be approximately considered to be canceled.

[0053] The present invention can design the laser optical path according to actual needs, so as to obtain the position of each optical path device in the laser optical path on the first component body and form a corresponding installation groove, and then solidify the first component body through the 3D laser printing SLA process, so as to obtain a resin model with installation grooves for each optical path device. In this way, during use, it is only necessary to install the optical path devices of each component into the corresponding installation groove to realize the laser optical path. Since the position of each optical path device in the resin model on the resin model is fixed and pre-designed, the laser optical path can be formed by installing each optical path device into the corresponding installation groove, and there is no need to install the frames, lenses, screws, etc. of each optical path device as in the prior art, resulting in problems such as poor stability of the laser optical path.

[0054] Preferably, in order to ensure the connection between the first component body and the external optical path equipment, the first component body of the present invention is also provided with a first input port 1, a second input port 2, an ionized light output port 15, a pump light output port 24, a detection light output port 33, and a cooling light output port 43, and each port is connected to the external equipment through the corresponding optical fiber to realize the transmission of the optical signal.

[0055] More preferably, the ionized light component is in communication with the first input port 1 and the second input port 2, and is used to receive the original light signal incident on the first component body through the first input port 1 and the first reference light signal incident on the first component body through the second input port 2. The ionized light component is also in communication with the ionized light output port 15 and the pump light component, and is used to perform optical splitting processing on the received original light signal to generate the first light signal and the second light signal, and to vertically reflect the second light signal to the pump light component, combine the first light signal with the first reference light signal to generate the ionized light signal, and output the ionized light signal to the ion trap quantum computer through the ionized light output port 15.

[0062] Preferably, the second optical signal generated after the first polarization beam splitter module 12 performs light splitting is vertically reflected into the pump optical component. That is, the connecting passage of the first polarization beam splitter module mounting groove 121 and the pump optical component mounting groove is vertical to ensure that the second optical signal is vertically reflected into the pump optical component.

[0063] Preferably, the pump light component includes a second light splitter component and a second half-wave plate 23.

[0071] Similarly, the cooling optical component mounting groove includes a reflector mounting groove 411 and a third half-wave plate mounting groove 421, which are used to mount the reflector 41 and the third half-wave plate 42 respectively.

[0072] Since the laser optical path in the present invention is pre-set, the laser optical path can be completed by simply installing each optical device into the corresponding mounting groove on the first component body. There is no need to install each device, thus avoiding the problem of unstable optical path due to problems such as frame, lens and screw installation.

[0073] The 3D laser printing used in the present invention is also called Additive Manufacturing, which is mainly different from the subtractive manufacturing of traditional turning, milling and grinding. In terms of process methods, it is a relatively mature technology with specific application scenarios. The main processes include: "resin wire deposition" (FDM), laser selective metal sintering / fusion (SLS / SLM), metal wire arc / laser manufacturing (WAAM / WLAM), photocurable resin (SLA), continuous photocuring technology (CLIP), etc. The laser optical path model used in the present invention uses the rigid resin of Formlabs, which has a lower thermal expansion coefficient and a higher elastic modulus, providing better calibration stability for the laser optical path system of the ion trap quantum computer; at the same time, the present invention uses the SLA process to realize the printing of the laser optical path model. In this way, in actual use, only simple optical installation and a few adjustable components are required in the laser optical path model, which can eliminate the need to adjust the optical frame adjustment screws or install lenses, and can greatly improve the stability of the ion trap quantum computer.

[0074] Preferably, since the ion trap in the ion trap quantum computer needs to be cooled from three different directions when cooling ions, the present invention also includes a second component body, and a fourth half-wave plate mounting groove 511, a second polarization beam splitter module mounting groove 531, a fourth spectrometer assembly mounting groove, and a fifth spectrometer assembly mounting groove arranged in the second component body.
