13WHY NOT SHRODINGER EQUATION??Number of particles = 200
Possible energy levels = 2200 Atoms in the Universe = 10 80, can accommodate state vector of around 100 electrons,
Even if this impossible computer is made,
Level spacing = 200 /2200 = 10-60
From Heisenberg Uncertainty relation, after spending universe life time , resolution = 10-33

Developing cheaper manufacturing technology & methodologyReducing cooling cost and increasing efficiencyReducing matrix size in the wireIncreasing critical temperature and critical magnetic field
To accomplish all of the above, One of the possible ways isDoing theory, in a close relation with experimental results, to predict room-temperature superconductivity.
