A quantum Szilard engine that can achieve two-level system hyperpolarization

Quantum computers, machines that perform computations exploiting quantum mechanical phenomena, could eventually outperform classical computers on some tasks, by utilizing quantum mechanical resources such as state superpositions and entanglement. However, the quantum states that they rely on to perform computations are vulnerable to a phenomenon known as decoherence, which entails the loss of quantum coherence and shift to classical mechanics.
