Circuit cutting with Quantum Serverless

View code


The limited number of qubits poses a challenge for practical usage of near-term quantum computation. Circuit cutting is a technique to increase the size of circuits we can run on quantum hardware at the cost of an additional sampling overhead. A larger quantum circuit can be decomposed by cutting its gates and wires into smaller circuits, which can be executed within the constraints of available quantum hardware. The results of these smaller circuits are combined to reconstruct the outcome of the original problem. Circuit cutting can also be used to engineer gates between distant qubits which would otherwise require a large SWAP overhead. Attendees of this tutorial will learn: the theory behind the latest circuit cutting techniques, how to cut a quantum circuit using the Circuit Knitting Toolbox, how to optimize a hybrid workflow with Quantum Serverless, and how circuit cutting can leverage the next iterations of quantum hardware architectures.
