This brief and simplified discernment is to suggest meaningful and practical ways or concepts and methods to design and build quantum computers (and systems). And which were suggested in diverse ways in many past discernments:
The most comprehensive, dynamic, effective, practical, and powerful quantum computers are those that are build based on the nature and ground of nature. For example, present quantum computers are build on human constructs, and therefore, have many oversights such as:
1.0 Nature is continuous (and beyond) rather than discrete. Discreteness should be used for specific applications rather as the norm.
2.0 Space-time-energy-frequency-matter or spectra-field are irreducible.
3.0 Present design is based on linear concept of quantum mechanics. Design should be based on non-linear or based on quantum spectra-field since as mentioned in 2.0, nothing has its own intrinsic inherent independent existence. Quantum mechanics is essential to understand the original creation of life and existence or All That Exist and Ever Exist. And continuation of causalities. However, once field or more specially spectra-field arose, quantum field science is relevant and applicable or essential.
4.0 As complementary to 4.0, entanglement may be perceived as linear even through it is not. However, intertwinement and entanglement implied non-linear. And therefore, should be mindful of the local and non-local cosmos.
5.0 Need to taking into consideration dark or immaterial spectra-field (spectra-field implies interdependent and interconnected or irreducible elements such as energy, field, frequency, phase, geometry, vibration, spcae, time, resonance, and so on). And as brief mentioned in 4.0.
6.0 Need also to consider organic and sentient. For example, quantum computer for specific tasks such as for medicine, health care, nurturing, and development.
7.0 Need to take into consideration underlying processes and mechanisms such as from dark or immaterial spectra-field.
8.0 From 7.0, explore and develop subtle quantum computing and system (as in subtle energy or spectra-field) rather than just ordinary quantum computer based on subtle spectra-field.
And as mentioned in diverse ways in past discernments, depending on functions and structures, geometric, dimensional or vector, phase, and biologic time phenomena can be or are reversible. However, evolution or wholeness process time is irreversible (https://www.epistemologyontologyfoundationinstitute.org/global-science-technology-and-innovation-movement/the-concept-of-time-a-grand-unified-reaction-platform)..

The just mentioned suggestions, can open up great creativity, ingenuity, and imagination or opportunities. In another words, the closer to the nature and ground of nature, the greater potentialities of possibilities.
Present concept and methods, beside very limited (versus infinite potentialities of possibility) of building quantum computers would take much time, efforts, and resources since many concepts and methods are either not inlign or contrary to the nature and ground of nature. And therefore, would not even lead to meaningful workable quantum computer and system much less practical and powerful quantum computer and system beyond present imagination.
