Gradually, as the quantum computers are being developed , their potential applications in various complex challenges are being realized. Upon the arrival of quantum computers at the scene, games can now be played on a quantum computer by designing quantum circuits on it. Though classical computers are enough to play the game virtually, quantum computers will always be better for tackling more and more complexity in a game. Since classical computation is used chess engines, in future, the engines can be made faster by using quantum computation, primarily because of their ability to use fewer steps to obtain at the same result as that of classical computers. And we can achieve the same with quantum computers by designing quantum circuits. However, an 8×8 chessboard is quite large and the existence of various pieces makes the circuit quite complex for us to build, so here we present quantum circuits for a 3×3 chessboard with only pawns in it. From here, it can be extrapolated to create, circuits for an 8×8 board and various other pieces. These quantum circuits can be designed on a quantum computer to play chess by any two users. We explain the working of the quantum circuits in detail with the algorithm behind the movement of pawns on the chessboard, in future, we can use this to later develop a quantum chess engine which will boost the quality of chess.
