Findings

Reversing the arrow of time impacts CNOT gate execution.

Future CNOT operations may influence past events.

Supports the concept of retrocausality in quantum physics.

Abstract

Recently it has been pointed out that an outstanding application of an IBM quantum computer is to reverse the arrow of time [Lesovik et al. Sci. Rep. 9, 1 (2019)]. The issue of the consequences of the reversal of the arrow of time on the execution of a CNOT gate by a quantum device is addressed. It is predicted that if the CNOT gate is executed towards the future then this was previously executed in the past. The above might confirm the paradigm that an event in the present time influences another event in the past time [2]. Such a physical phenomena is called retrocausality.
