MULTI-STEP QUANTUM BASIS STATE SHIFT

Resumen de: EP4760603A1

Disclosed is a method and a quantum circuit to be utilised for performing a multi-step quantum basis state shift. For a state vector space having the size of 2^N+1, a full shift register comprises N+1 qubits. A last qubit (q_N+1) of the full shift register is a superposition qubit, which allows for defining a superposition of substates. The superposition qubit is used to determine which substates are to be incremented and which substates are to be decremented. Even substates to be incremented can be incremented by simply applying a step of inverting an i+1^th qubit (q_i+1), namely a step qubit. Similarly, odd substates to be decremented can be decremented by applying the same step of inverting. Remaining steps of the quantum circuit are employed to perform a rearrangement of the even substates to be incremented, the even substates to be decremented, the odd substates to be incremented, and the odd substates to be decremented, such that applying the step of inverting performs the multi-step quantum basis state shift in one go.
