• Abstract: Games involving quantum strategies often yield higher payoff. Here, we study a practical realization of the three-player dilemma game using the superconductivity-based quantum processors provided by IBM Q Experience. We analyze the persistence of the quantum advantage under corruption of the input states and how this depends on parameters of the payoff table. Specifically, experimental fidelity and error are observed not to be properly anti correlated, i.e., there are instances where a class of experiments with higher fidelity yields a greater error in the payoff. Further, we find that the classical strategy will always outperform the quantum strategy if corruption is higher than half.

• Repeated quantum game as a stochastic game: Effects of the shadow of the future and entanglement [0.0]
  We present a systematic investigation of the quantum games, constructed using a novel repeated game protocol. We find that how two pure strategies fare against each other is crucially dependent on the discount factor. In the quantum game setup, always-defect strategy can be beaten by the tit-for-tat strategy for high enough discount factor.

• Photonic implementation of the quantum Morra game [69.65384453064829]
  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.

  In particular, quantum entanglement can be a much more powerful resource than local operations and classical communication to play these games. This result shows a strong contrast to the bipartite case, where it was recently proved that the entangled bias is always upper bounded by a universal constant times the one-way classical communication bias.

That is, if the referee has information on the physical realization and strategy of the players, he can bias the game through filtered randomness and increase his winning probability.

We show that it is in general impossible to realize a two-party quantum functionality with black-box simulation in the case of malicious quantum adversaries. We provide a compiler that takes as input a classical proof of quantum knowledge (PoQK) protocol for a QMA relation R and outputs a zero-knowledge PoQK for R that can be verified by classical parties.

• Fault-tolerant Coding for Quantum Communication [71.206200318454]
  encode and decode circuits to reliably send messages over many uses of a noisy channel. For every quantum channel $T$ and every $eps>0$ there exists a threshold $p(epsilon,T)$ for the gate error probability below which rates larger than $C-epsilon$ are fault-tolerantly achievable. Our results are relevant in communication over large distances, and also on-chip, where distant parts of a quantum computer might need to communicate under higher levels of noise.
