Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a quantum circuit that autonomously and efficiently tunes the quantum state of qubits through locally integrated components. The circuit includes a qubit module, a bias control, a read-out unit, and an adjustment unit that uses an iterative algorithm to automatically reach a desired quantum state without relying on external computers or complex wiring. All these components are physically assembled together, optimizing both performance and scalability.

Patent Abstract

The invention relates to a quantum circuit (1) comprising the following circuit components (3, 4, 5, 6, 7, 8) that are locally associated with one another: a qubit circuit (3) with quantum states that can be adjusted according to a bias signal; a bias circuit (4) for applying an output bias signal (11), encoded by an input signal (10) of the bias circuit (4), to the qubit circuit (3); a read-out circuit (5), communicatively connected to the qubit circuit (3), for reading out a quantum state adjusting in response to the applied output bias signal (11) and for outputting a read-out signal (13) encoding the read-out quantum state; and an adjusting circuit (6), communicatively connected to the bias circuit (4) and the read-out circuit (5), for executing an iterative algorithm which applies iterative values for the input signal (10) to the bias circuit (4), starting with an initial value, and continues the iteration, according to the respective responsively output read-out signal (13) of the read-out circuit (5), until the output read-out signal (13) corresponds to the adjustment of a desired quantum state.
