Abstract

A quantum bit control apparatus, including a control signal generator, optoelectronic detectors, a quantum chip, and a shielding apparatus, the optoelectronic detectors are disposed in the shielding apparatus, and an inner part of the shielding apparatus is in a vacuum state. The control signal generator is disposed in a first temperature area, and is configured to generate optical control signals and send the N optical control signals to the optoelectronic detectors. The optoelectronic detectors are disposed in a second temperature area having a temperature lower than of the first temperature area. The N optoelectronic detectors are configured to convert the received optical control signals into electronically controlled signals and send the electronically controlled signals to the quantum chip. The quantum chip is disposed in the second temperature area, and controls a quantum bit in the quantum chip based on the electronically controlled signals.
