Title: Innovations of Yongjing Cai
Introduction
Yongjing Cai is a prominent inventor based in Zurich, Switzerland. He has made significant contributions to the field of quantum technology, holding a total of three patents. His work focuses on advancing the capabilities of quantum bit control and key generation methods.
Latest Patents
One of his latest patents is the "Quantum bit control apparatus." This apparatus includes a control signal generator, optoelectronic detectors, a quantum chip, and a shielding apparatus. The optoelectronic detectors are positioned within the shielding apparatus, which maintains a vacuum state. The control signal generator operates in a first temperature area and generates optical control signals that are sent to the optoelectronic detectors. These detectors, located in a second temperature area with a lower temperature, convert the received optical control signals into electronically controlled signals for the quantum chip. The quantum chip then controls a quantum bit based on these signals.
Another notable patent is the "Key generation device and method." This method involves modulating a first key to create a modulated optical signal, which is then split into two sub modulated optical signals. The first sub modulated optical signal is attenuated to ensure the number of photons in each period is below a preset value. This attenuated signal is sent to a receiving device, while the second key is extracted from the second sub modulated optical signal and stored for future use.
