.... interactions between photons and electron spins on individual atoms [24, 45] and other experimentalists work with vibrational states in assemblages of interacting atoms [14] Other proposals for implementation technologies for quantum computing, from various communities, include Teich et al. 88 [43], Lloyd 93 94 [33, 34] DiVincenzo 95 a [20] Sleator Weinfurter 95 [40] Barenco et al. 95 b [3] and Chuang Yamamoto 95 [13] The main lesson to be learned from this long list of proposals is that the details of the physical implementation of quantum computers is just an ....

Later Lloyd [Llo93] extended the use of heteropolymers to QC, using the energy states to store the state of the qubits. The coupling of qubits may be via electric dipole moments which causes ....

....in polynomial time on a quantum computer with a small probability of error. Currently, nobody knows how to build a quantum computer, although it seems as though it might be possible within the laws of quantum mechanics. Some suggestions have been made as to possible designs for such computers [Teich et al. 1988, Lloyd 1993, 1994a, Cirac and Zoller 1995, DiVincenzo 1995, Sleator and Weinfurter 1995, Barenco et al. 1995b, Chuang and Yamomoto 1995] but there will be substantial difficulty in building any of these [Landauer 1995, Unruh 1995, Chuang et al. 1995, Palma et al. 1995] The most difficult ....

....It is meant to be more thought provoking than real: I don t suggest that experimentalists try immediately to go out to build this device, but I do hope that it provides a springboard for productive thought on what really needs to be done to perform quantum computation. Of course, others before me [15,16] have made proposals for, and explored the feasibility of [17] potentially realizable quantum computers ; the one I now present exploits somewhat different physical principles than the previous proposals, and hopefully provides ideas for how some of the monstrous obstacles (like the ones ....

....superpositions of physical states, which is one of the inherent properties of quantum physics. Several researchers have suggested that the QTM might have a potential for a new type of computer [4, 7, 19] Several researchers have proposed possible designs of computers based on Deutsch s QTM [11, 12, 18]. The possible advantages of the QTM are as follows: ffl Every finitely realizable physical system can be perfectly simulated by a QTM. ffl A computer based on the QTM may be capable of dissipating very small amount of energy per step. ffl Several researchers pointed out the possibilities of ....

.... problem to modern cryptography [6] has led to redoubled interest in the design and construction of quantum computational nanodevices [7] It should be emphasized that the goal here is a computational device which will run quantum algorithms, not a quantum device which will run deterministic [8,9] or probabilistic [10] algorithms. For a variety of reasons the wire and gain problems, and the pragmatic observation that an array of simple devices is often easier to design and build than a single, more complicated device it seems likely that massive parallelism will optimize nanoscale ....

Currently, nobody knows how to build a quantum computer, although it seems as though it could be possible within the laws of quantum mechanics. Some suggestions have been made as to possible designs for such computers [30, 22, 23, 12], but there will be substantial difficulty in building any of these [18, 32] Even if it is possible to build small quantum computers, scaling up to machines large enough to do interesting computations could present fundamental difficulties. It is hoped that this paper will stimulate research on ....
