Summary

This hands-on session, part of the WISER Summer Program 2026, introduces the Quantum Divide and Conquer (DQI) technique for optimization. Catalina Albornoz, a senior research engagement manager at Xanadu, guides participants through the fundamentals of PennyLane, an open-source quantum computing framework. The session begins with an overview of quantum optimization, emphasizing the use of quantum interference to amplify correct solutions. It then focuses on DQI, a method that encodes problem data into the frequency domain using the Walsh-Hadamard transform, making state preparation more efficient. The presenter explains the steps of DQI: preparing Dicke states, encoding constraints via phases, and decoding using a lookup table for small examples. The core of the session is a live coding demonstration in PennyLane, where participants implement a Max-XOR-SAT problem. The tutorial includes code for defining the objective function, preparing states, and sampling results. The session concludes with an invitation to explore the provided notebooks and the PennyLane Challenge for further practice.

Critical Evaluation

Value of the Information & Strength of the Argument

The session provides valuable practical knowledge on implementing DQI using PennyLane, a leading quantum computing framework. The presenter’s approach is hands-on, guiding viewers through code and explaining the underlying concepts in an accessible manner. The argumentation is solid, as it builds on established quantum computing principles and demonstrates the algorithm’s application to a specific optimization problem. However, the session does not provide a deep theoretical justification for DQI, instead focusing on practical implementation. The value lies in its tutorial nature, enabling viewers to replicate the example and learn the workflow.
