• Authors: Kazuki Ikeda and Shoto Aoki
• Abstract summary: We analyze a quantum economy in which players produce and consume quantum goods. We find distinctive aspects of quantum games that cannot be explained by conventional classical games. Those novel properties imply that quantum games also shed new light on theories of mechanism design, auction and contract in the quantum era.

• Abstract: The quest of this work is to present discussions of some fundamental questions of economics in the era of quantum technology, which require a treatment different from economics studied thus far in the literature. A study of quantum economic behavior will become the center of attention of economists in the coming decades. We analyze a quantum economy in which players produce and consume quantum goods. They meet randomly and barter with neighbors bilaterally for quantum goods they produced. We clarify the conditions where certain quantum goods emerge endogenously as media of exchange, called quantum commodity money. As quantum strategies are entangled, we find distinctive aspects of quantum games that cannot be explained by conventional classical games. In some situations a quantum player can acquire a quantum good from people regardless of their strategies, while on the other hand people can find quantum strategies that improve their welfare based on an agreement. Those novel properties imply that quantum games also shed new light on theories of mechanism design, auction and contract in the quantum era.

  In the 1970s, Wiesner introduced the concept of quantum money, where quantum states generated according to specific rules function as currency. Quantum computers capable of minting and preserving quantum money have not yet emerged. Existing quantum channels are not stable enough to support the efficient transmission of quantum states for quantum money.

  We study a faithful translation of a two-player quantum Morra game, which builds on previous work by including the classical game as a special case. We propose a natural deformation of the game in the quantum regime in which Alice has a winning advantage, breaking the balance of the classical game. We discuss potential applications of the quantum Morra game to the study of quantum information and communication.

  We explore the applicability of quantum-data learning to practical problems in high-energy physics. We make use of ansatz based on quantum convolutional neural networks and numerically show that it is capable of recognizing quantum phases of ground states. The observation of non-trivial learning properties demonstrated in these benchmarks will motivate further exploration of the quantum-data learning architecture in high-energy physics.
