This is an abstract for a presentation given at the
10th Foresight Conference on Molecular Nanotechnology

 

One of the most important potential application of nanotechnology will be the development of new information devices working on quantum mechanical principles. The poster considers fundamental quantum mechanical restrictions on the parameters of computer hard molecular nano-memory. Quantum mechanics fundamentally restricts the parameters of computer hard memory. Tunneling through potential barrier imposes a lower limit on the size of the electron and proton quantum memory (QMEM). The quantum mechanical uncertainty principle for energy imposes fundamental upper and lower limits on the maximum recording and reading speed. The information exchange rate cannot be faster than 20 bits/fsec for molecular QMEM. On the other hand the relaxation time of electron and proton QMEM must be short enough. It was found that the product of maximum available time to store the information by square root from its amount is a constant value for the given design of QMEM. The area of the parameters of QMEM was determined where the probability of destroying the information at the point of storage, recording and reading is so small that it is possible to create practical devices of QMEM. There is no way to overcome the discovered quantum mechanical restrictions of QMEM by any means of technical advances. These are fundamental limits that nature imposes on their development.
