Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments.
Referring to fig. 1, the present invention provides a quantum polarization entanglement-based oscillator, wherein the oscillator includes a first switching value output circuit and a second switching value output circuit.
Referring to fig. 3, the first switching value output circuit and the second switching value output circuit each include a photon processing module and an output module. The photon processing module comprises a polarizer 308, an electro-optic modulation crystal 302, a light source device 301 and a double-slit diffraction device 307. And the output module comprises a power supply, a photosensitive module and a resistor. The power supply is VCC in the figure, and the resistor is R306 in the figure. The first switching value output circuit and the second switching value output circuit utilize the working principle of a quantum polarization entanglement experiment in the working process. Specifically, as shown in fig. 2, a solid line 201 indicates a light intensity distribution when bright and dark alternate stripes are generated, and a solid line 202 indicates a light intensity distribution when bright and dark alternate stripes are not generated. The conditions for generating the bright and dark alternate stripes are as follows: a pair of photons in an entangled state are required to pass through the oscillating polarizer and the double slit diffraction device, respectively, and the distance from the photons to the polarizer is smaller than the distance from the photons to the double slit diffraction device. The purpose of controlling whether the bright and dark alternate stripes are generated or not is achieved by controlling the starting vibration state of the polaroid. The photodiode is placed at the position where the solid line 201 produces the maximum light intensity. If the polarizer starts to vibrate, stripes with alternate light and shade are generated, the light intensity distribution is shown as a solid line 201, and at the moment, the photodiode is conducted and outputs a low level of 0; if the polarizer is not vibrated, stripes with alternate light and dark are not generated, the light intensity distribution is as shown by a solid line 202, and at this time, although a certain light intensity exists, the conduction threshold of the photodiode is not reached, so that the photodiode outputs a high level 1.
In the embodiment of the present application, using the operation principle shown in fig. 2, the distance between the polarizer 308 and the photon detection device 303 and the electro-optical modulation crystal 302 is shorter than the distance between the double-slit diffraction device 307 and the electro-optical modulation crystal 302, and only then, the purpose of controlling whether to generate bright and dark alternate fringes can be achieved by controlling the oscillation starting state of the polarizer. The light source device 301 emits photons to the electro-optically modulated crystal 302. After passing through the electro-optical modulation crystal 302, a pair of photons in an entangled state is generated, wherein one photon passes through the polarizer 308, the other photon passes through the double-slit diffraction device 307, and then reaches a switching value output circuit composed of a power supply VCC, a photodiode D305 and a resistor R306, and a photon detection device 309 is disposed beside the photodiode D305 for detecting the photons. When the input end 304 outputs a high level, the polarizer 308 starts to vibrate, and a polarization phenomenon is generated when a photon passes through the polarizer 308, and at this time, another photon passes through the double-slit diffraction device 307 and then generates light and dark stripes, so that the photodiode D305 is turned on, a low level 0 is output, and the resistor R306 outputs a high level 1.
The truth table is shown in the following table:
input terminal | Photodiode | Resistance (RC) |
1 | 0 | 1 |
0 | 1 | 0 |
Referring to fig. 1, a connection point of an input terminal 103 of the first switching value output circuit and an output terminal of an output module of the second switching value output circuit 102 serves as an input terminal 101 of the oscillator; a first output end of an output module of the first switching value output circuit 103 is connected with an input end of the second switching value output circuit 102; a first output terminal 105 of the output module of the first switching value output circuit 103 is used for controlling the oscillation starting state of the polarization plate in the second switching value output circuit 102, a second output terminal of the output module of the first switching value output circuit is used as an output terminal 104 of the oscillator for outputting the oscillation voltage, and an output terminal 106 of the output module of the second switching value output circuit is used for controlling the oscillation starting state of the polarization plate in the first switching value output circuit.
In the present embodiment, when the oscillator operation is performed by using the circuit shown in fig. 3, the operation principle is as follows:
taking a working cycle as an example, when a high level 1 is input at the input end of the oscillator, the polarizer in the first switching value output circuit starts to oscillate, bright and dark stripes are generated, the photodiode is conducted, and at this time, the resistor of the first switching value output circuit outputs the high level 1, and the photodiode outputs the low level 0. The low level 0 output by the photodiode of the first switching value output circuit is used as the input of the second switching value output circuit, so that the polarizing plate of the second switching value output circuit cannot start oscillation, at the moment, light and shade alternate stripes cannot be generated, the photodiode of the second switching value output circuit outputs a high level 1, and the resistor outputs a low level 0. The resistance output of the second switching value output circuit is used as the input of the first switching value output circuit to control whether the polaroid of the first switching value output circuit starts oscillation or not. When the resistance output low level 0 of the second switching value output circuit is used as the input of the first switching value output circuit, the polaroid in the first switching value output circuit cannot start oscillation, no bright and dark alternate stripes are generated, and the photodiode is cut off, at the moment, the resistance output low level 0 of the first switching value output circuit and the photodiode output high level 1. The high level 1 output by the photodiode of the first switching value output circuit is used as the input of the second switching value output circuit, so that the polarizing plate of the second switching value output circuit starts to vibrate, at the moment, stripes with alternate light and shade are generated, the photodiode of the second switching value output circuit outputs the low level 0, and the resistor outputs the high level 1. The resistance output of the second switching value output circuit is used as the input of the first switching value output circuit. The circuit is circulated, and the resistance output end of the first switching value output circuit can output periodic oscillation voltage.
In some embodiments, the photodiode in fig. 3 may also be replaced with a photoresistor. The common manufacturing material of the photoresistor is cadmium sulfide, and in addition, materials such as selenium, aluminum sulfide, lead sulfide, bismuth sulfide and the like are also used. These materials have the property of rapidly decreasing their resistance under irradiation with light of a specific wavelength. The carriers generated by illumination all participate in conduction, and drift under the action of an external electric field, electrons rush to the anode of a power supply, and holes rush to the cathode of the power supply, so that the resistance value of the photoresistor is rapidly reduced.
In some embodiments. The electro-optic modulation crystal comprises a BBO crystal. The BBO crystal has obvious comprehensive advantages and good performance in nonlinear optical crystals, has extremely wide light transmission range, extremely low absorption coefficient and weaker piezoelectric ringing effect, and has higher extinction ratio, larger phase matching angle, higher light damage resistance threshold, broadband temperature matching and excellent optical uniformity compared with other electro-optical modulation crystals.
While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
