Riverlane and dividiti recently had the exciting opportunity to co-organize the first Quantum Hackathon in France, with support from Quantonation and IBM. Around 100 participants with varying abilities and backgrounds converged at 42 in Paris to take part in the event.
The hackathon challenge was framed in a similar fashion to a machine learning classification problem. Participants were given a set of vectors as training data, labelled by either +1 or -1. The vectors each represented a quantum state encoded onto qubits, and the challenge was to learn a quantum circuit that transforms the state to one that gives the correct parity label upon measurement. This problem gave users the opportunity to explore some of the fundamental aspects of quantum computing, using a classical quantum simulator with the Qiskit quantum framework from IBM.
Participants submitted their code using Quantum Collective Knowledge (QCK), a framework developed by dividiti to benchmark existing quantum computing systems, pinpoint the state-of-the-art and forecast future developments. QCK builds upon Collective Knowledge, a universal open-source framework for reproducible and collaborative R&D. The quality of submissions could then be ranked in a collaborative setting, as seen here, sparking further discussion on the most efficient solutions to each problem. Many teams were successful at completing all tasks!
