Researchers have developed a more resource-efficient Quadratic Unconstrained Binary Optimization (QUBO) formulation for currency arbitrage detection. This new method incorporates realistic constraints like starting cycles from a specific currency and accounting for trading fees, requiring fewer logical variables than previous QUBO encodings. The formulation includes an exact anchor-gauge reweighting of exchange rates to address hardware precision limitations. Benchmarking against classical simulated annealing and prior QUBO methods demonstrated its effectiveness in finding profitable, fee-adjusted cycles. AI
