Strategie kwantowe. the simplest case of a classical game between two players with two strategies each, both the players can use a bit a '0' or a '1' to convey their choice of strategy.

Quantum game theory

A popular example Strategie kwantowe. such a game is the prisoners' dilemmawhere each of the convicts can either cooperate or defect: withholding knowledge or revealing that the other committed the crime. In the quantum version of the game, the bit is replaced by the qubitwhich is a quantum superposition of two or more base states.

Each of the spin states can be used to represent each of the two strategies available to the players. When a measurement is made on the electron, it collapses to one of the base states, thus conveying the strategy used by the player.

Entangled initial states[ edit ] The set of qubits which are initially provided to each of the players to be used to convey Strategie kwantowe. choice of strategy may be entangled.

For instance, Strategie kwantowe. entangled pair of qubits implies that an operation performed on one of the qubits, affects the other qubit as well, thus altering the expected pay-offs of the game. Superposition of strategies to be used on initial states[ edit ] The job of a player Strategie kwantowe.

a game is to choose a strategy. In terms of bits this means that the player has to choose between 'flipping' the bit Wycena opcji zapasow 409a its opposite state or leaving its current state untouched.

When extended to the quantum domain this implies that the player can rotate the qubit to a new state, thus changing the probability amplitudes of each of the base states. Such operations on the qubits are required to be unitary transformations on the initial state of the qubit.

This is different from Strategie kwantowe. classical procedure which chooses the strategies with some statistical probabilities. Multiplayer games[ edit ] Introducing quantum information into multiplayer games allows a new type of "equilibrium strategy" which is not found in traditional games.

The entanglement of players' choices can have the effect of a contract by preventing players from profiting from other player's betrayal.

Zajmowali się różnymi dziedzinami fizyki. W roku obaj ogłosili prace, które mogły przynieść im Nagrodę Nobla, choć zapewne żaden z nich z początku w to nie wierzył.
