Chaos prevention in a correlated noisy dynamic Stackelberg duopoly game through the B-gate

Published May 7, 2025• 4 citations

Abstract

Abstract Recent economic research has focused on applying quantum mechanical models to understand complex markets. Real markets are usually complex with nonlinear inverse demand functions and dynamic participants. Furthermore, when these market games are quantized, players interact via quantum channels that are prone to decoherence. In this work, owing to the complexity of real markets, we introduce noise and memory in a dynamic quantum Stackelberg duopoly game for the first time. We shed light on the significance of two-qubit entangling operators, particularly special perfect entanglers (SPEs), in controlling chaos. The following noteworthy observations are made: First, although entangling operators cannot prevent monopolies in the market, they can shift leader dominance to follower dominance. Second, numerical analysis highlights the significance of the B-gate in a correlated noisy channel as a chaos control. We also highlight the significance of the controlled-NOT (CNOT), and double-CNOT (DCNOT) gates in controlling chaos in noisy, memoryless channel 2. Finally, we show that the CNOT and DCNOT gates are more sensitive than the B-gate. These novel features of two-qubit entangling operators in correlated, noisy and dynamic market games shed new light on the role of SPEs in quantum dynamic game settings.

Two-qubit entangling operators as chaos control in a discrete dynamic Cournot duopoly game

A. V. S. Kameshwari, S. Balakrishnan

The current trend in economics research is to incorporate quantum mechanical concepts to increase the security of business models. This interdisciplinary field of study represents real-world market dynamics more closely than do its classical counterparts. In this paper, we shed light on the significance of the two-qubit entangling operators in controlling chaos. We introduce a modified Eisert-Wilkens-Lewenstein scheme in a nonlinear Cournot duopoly game with complete and incomplete information. By doing so, the following interesting results are obtained: To begin, monopoly in a duopoly game can be avoided with the use of special perfect entanglers. Also, the stability analysis shows that there exists a class of entangling operators which can stabilize an unstable system and vice versa. Second, numerical analysis highlights the two-qubit entangling operators which can stabilize a chaotic system or at least delay chaos. Finally, we show that with an appropriate choice of initial state and speed of adjustments, entangling operators can decrease the sensitivity of the system. In short, while we know the importance of entangling operators in quantum game theory, in this paper we indicate the significance of operators in the context of a chaotic system.

Interplay of noise, memory and entangling operator in quantum Stackelberg-Bertrand duopoly game

A. V. S. Kameshwari, S. Balakrishnan

Abstract In this work, we make an attempt to understand how noise, memory and entangling operators collectively decide the profit of the firms Here we have studied the quantum version of Stackelberg-Bertrand duopoly game using modified EWL scheme in both correlated and uncorrelated noise channels. When this game is analyzed for amplitude damping channels following interesting results are obtained: Firstly, decoherence in channel 2 effects the profit function of the firms more than that of channel 1. Secondly, in the case of correlated noise memory prevents the death of entanglement at maximum noise. Finally, the profit function of the firms depends upon noise, memory, strategies, and entangling operator in any given game setting.

Quantum Stackelberg duopoly in the presence of correlated noise

Salman Khan, Muhammad Asif Ramzan, Majid Khan

We study the influence of entanglement and correlated noise using correlated amplitude damping, depolarizing and phase damping channels on the quantum Stackelberg duopoly. Our investigations show that under the influence of an amplitude damping channel a critical point exists for an unentangled initial state at which firms get equal payoffs. The game becomes a follower advantage game when the channel is highly decohered. Two critical points corresponding to two values of the entanglement angle are found in the presence of correlated noise. Within the range of these limits of the entanglement angle, the game is a follower advantage game. In the case of a depolarizing channel, the payoffs of the two firms are strongly influenced by the memory parameter. The presence of quantum memory ensures the existence of the Nash equilibrium for the entire range of decoherence and entanglement parameters for both the channels. A local maximum in the payoffs is observed which vanishes as the channel correlation increases. Moreover, under the influence of the depolarizing channel, the game is always a leader advantage game. Furthermore, it is seen that the phase damping channel does not affect the outcome of the game.

The influence of entanglement and decoherence on the quantum Stackelberg duopoly game

Zhu Xia, Le‐Man Kuang

In this paper, we investigate the influence of entanglement and decoherence on the quantum Stackelberg duopoly (QSD) game. It is shown that the first-mover advantage can be weakened or enhanced due to the existence of entanglement for the QSD game without decoherence. The influence of decoherence induced by the amplitude damping and the phase damping are explicitly studied in the formalism of Kraus operator representations. We show that the amplitude damping drastically changes the Nash equilibrium of the QSD game and the profits of the two players while the phase damping does not affect the Nash equilibrium and the profits of the two players. It is found that under certain conditions there exists a 'critical point' of the damping parameter for the amplitude damping environment. At the 'critical point' the two players have the same moves and payoffs. The QSD game can change from the first-mover advantage game into the follower-mover advantage game when the damping parameter varies from the left-hand-side regime of the 'critical point' to the right-hand-side regime.

Backwards-induction outcome in a quantum game

Azhar Iqbal, A. H. Toor

In economics, duopoly is a market dominated by two firms large enough to influence the market price. Stackelberg presented a dynamic form of duopoly that is also called the ``leader-follower'' model. We give a quantum perspective on the Stackelberg duopoly that gives a backwards-induction outcome same as the Nash equilibrium in the static form of duopoly also known as the Cournot's duopoly. We find the two-qubit quantum pure states required for this purpose.

Influence of memory effects on quantum Stackelberg duopoly game under amplitude damping channel

Xiang-Ping Liao, Xin-Yi 馨仪 Wang 王

Abstract We study the influence of memory effects on the quantum Stackelberg duopoly game through an amplitude-damping channel where successive uses of the channels are correlated. It is shown that the memory effects can drastically change the Nash equilibrium and the payoffs of the two firms. As the degree of channel memory increases, there exists a Nash equilibrium for the entire range of the entanglement parameter. Similarly, the presence of memory ensures the existence of the Nash equilibrium for the whole range of the decoherence parameter both for entangled and unentangled initial states. Moreover, quantum memory leads to a ‘critical point’ of the damping parameter, at which both firms are equally benefited. With the maximum-memory effect, the position of the ‘critical point’ moves to the place of fully decohered.

We study the influence of entanglement and correlated noise using correlated amplitude damping, depolarizing and phase damping channels on the quantum Stackelberg duopoly. Our investigations show that under the influence of an amplitude damping channel a critical point exists for an unentangled initial state at which firms get equal payoffs. The game becomes a follower advantage game when the channel is highly decohered. Two critical points corresponding to two values of the entanglement angle are found in the presence of correlated noise. Within the range of these limits of the entanglement angle, the game is a follower advantage game. In the case of a depolarizing channel, the payoffs of the two firms are strongly influenced by the memory parameter. The presence of quantum memory ensures the existence of the Nash equilibrium for the entire range of decoherence and entanglement parameters for both the channels. A local maximum in the payoffs is observed which vanishes as the channel correlation increases. Moreover, under the influence of the depolarizing channel, the game is always a leader advantage game.

At the 'critical point' the two players have the same moves and payoffs.
