“…However, this model cannot account for complex amplitudes of the pure state of the qubit. While arguments about how a 2 qubit state with complex coefficients can be converted to a real valued 3 qubit system has been discussed in the works of [18], making a few changes to the model described by V. Hlukhov in [5] and [4] would allow for the use of these complex probability amplitudes. This ideology is comprehensively discussed in the subsection 4.5 of this paper.…”

“…While real quantum computers are probabilistic devices that are analog in nature, FPGA based quantum co-processors are of digital nature. These devices make use of digital qubits, which in turn are based on classical logic circuits with probabilistic outputs [4]. Digital qubits allow for the offloading of some calculations that can benefit from parallelization.…”

This paper focuses on usage of digital qubits on a digital quantum computing platform implemented on FPGAs. Modifications have been made to existing digital qubit standards to account for complex probability amplitudes and not only real ones. This paper introduces an improved transient effect ring-oscillator based TRNG used in the scope of this project. The objective of this was to simulate the addition of environmental noise in a digital setting. Using the newly designed digital qubits, a few quantum logic gates have been designed to work on the FPGA platform using Verilog. These logic gates have then been used to implement entanglement on a digital hardware platform. Furthermore, this paper implements communication between two digital quantum computers over both wired and wireless media by transmitting alphabetical messages as qubits and compares the same with transmission involving classical digital bits only.
