Disclosed herein is a method to facilitate establishing a connection between an access-seeking device and an access granting device. The method may include receiving, using a communication device, a Quantum Level Security (QLS) code from the access-seeking device. Further, the QLS code may be generated by the access-seeking device based on at least one QLS function and at least one parameter. Further, the method may include receiving, using the communication device, an independent QLS code generated by an access granting device based on the at least one QLS function and the at least one parameter. Further, the method may include comparing, using a processing device, the QLS code and the independent QLS code. Further, the method may include establishing, using the communication device, the connection between the access-seeking device and the access granting device based on a result of the comparing.
