1st Edition. FIRST EDITION IN ORIGINAL PICTORIAL WRAPS OF A 2001 PAPER C-AUTHORED BY SETH LLOYD. The authors "exploit â??quantum weirdness' [in an effort to] dramatically improve the precision of radar, sonar, the global positioning system and other object locators.[They] propose "that taking advantage of the quirky nature of certain quantum pulses would create a significantly more accurate object locator" (Ball, Nature Online, 2002). "The precision with which objects can be located depends on the accuracy with which the arrival time of the pulses can be determined. â??Our work shows that by exploiting 'quantum weirdness,' one can in principle dramatically enhance the precision of such pulse-timing methods,' Lloyd said. â??Counterintuitive features of quantum mechanics such as entanglement (quantum correlations that are 'excessive,' or greater than classical) and squeezing (the reduction of quantum noise levels below their semiclassical limit) can be employed to overcome the classical limits in these procedures'" (Halber, Quantum Weirdness, MIT, 2001) Seth Lloyd, a self-proclaimed â??quantum mechanic', is a professor of mechanical engineering and physics at MIT (MIT). His research area "is the interplay of information with complex systems.He has performed seminal work in the fields of quantum systems, quantum computation, quantum communication and quantum biology including proposing the first technologically feasible design for a quantum computer, demonstrating the viability of quantum analog computation, proving quantum analogs of Shannon's noisy channel theorem, and designing novel methods for quantum error correction and noise reduction" (MIT). We offer two of Lloyd's papers separately, his 1993 paper wherein he is the first to "propose the first technologically feasible design for a quantum computer" (WP). We also offer his 1996 paper separately, the 1st proof "that universal computers can be built from quantum mechanical systems" (Stolz, Quantum, 129). The authors argue: "A wide variety of positioning and ranging procedures are based on repeatedly sending electromagnetic pulses through space and measuring their time of arrival. The accuracy of such procedures is classically limited by the available power and bandwidth. Quantum entanglement and squeezing have been exploited in the context of interferometry, frequency measurements, lithography and algorithms. Here we report that quantum entanglement and squeezing can also be employed to overcome the classical limits in procedures such as positioning systems, clock synchronization and ranging. Our use of frequency-entangled pulses to construct quantum versions of these protocols results in enhanced accuracy compared with their classical analogues. We describe in detail the problem of establishing a position with respect to a fixed array of reference points" (Lloyd, 2001, 417). Philip Ball, writing in Nature Online in 2002, explains it this way: "Whereas cricket balls can be bowled with a spin to left or right, two quantum particles can be let loose in an entangled 'superposition' - a mixture of both spin states. The entangled quantum particles' states are interdependent. Only when their spin is measured does their spin state resolve into 'left' or 'right'. Thus, measuring the spin of one particle automatically decides the other. The use of photons whose frequencies are entangled means that photons in a laser pulse no longer arrive at a detector independently, Lloyd's team propose. If the frequency of one pulse depends on that of one of the others, travel times get bunched together, reducing uncertainty in timing. Ten entangled pulses measure up better than ten normal ones - partly because averaging helps to remove random errors. In addition, frequency-entangled pulses improve accuracy more quickly as their numbers increase" (Ball). CONDITION & DETAILS: Original wraps. 4to.

Original wrappers. Fine copy of the full issue. [++] 3300+ citations for this paper by Lloyd in which he shows the Feynman quantum computer conjecture (Feynman, "Simulating Physics with Computers" in "International Journal of Theoretical Physics", 21, 467, 1982) to be correct by proving that a quantum system can be simulated in a quantum computer. The very short and sweet abstract from the Lloyd paper simply states: "Feynman's 1982 conjecture that quantum computers can be programmed to simulate any local quantum system, is shown to be correct." That's it. [++] "Since their introduction in 1980 quantum computers have been investigated extensively. A comprehensive review can be found in. The best known problem that quantum computers can in principle solve more efficiently than classical computers is factoring. In this article I present another type of problem that in principle quantum computers could solve more efficiently than a classical computer that of simulating other quantum systems. In 1982, Feynman conjectured that quantum computers might be able to simulate other quantum systems more efficiently than classical computers. Quantum simulation is thus the first classically difficult problem posed for quantum computers. Here I show that a quantum computer can in fact simulate quantum systems efficiently as long as they evolve according to local interactions."

1st Edition. FIRST EDITION IN ORIGINAL WRAPS OF THE FIRST PROOF "THAT UNIVERSAL COMPUTERS CAN BE BUILT FROM QUANTUM MECHANICAL SYSTEMS" (Stolz, Quantum Computing, 129). In 1982 Feynman conjectured that quantum computers can be programmed to simulate any local quantum system. In this paper, Seth Lloyd proves that Feynman was correct. He "prove[s] that a universal quantum simulator is possible by showing that a quantum computer can be programmed to simulate any local quantum system efficiently" (History of Science: The Wenner Collection; Wikipedia). "Quantum computing studies theoretical computation systems (quantum computers) that make direct use of quantum-mechanical phenomena, such as superposition and entanglement, to perform operations on data" (Gershenfeld, "Quantum Computing with Molecules" in Scientific American, June 1988). "Quantum computers are different from binary digital electronic computers based on transistors. Whereas common digital computing requires that the data be encoded into binary digits (bits), each of which is always in one of two definite states (0 or 1), quantum computation uses quantum bits, which can be in superpositions of states" (Wikipedia). Seth Lloyd, a self-proclaimed â??quantum mechanic', is a professor of mechanical engineering and physics at MIT. His â??potentially realizable' quantum computer is described as "arrays of weakly coupled quantum systems. Computation is effected by a sequence of electromagnetic pulses that induce transitions between locally defined quantum states. in a crystal lattice" (Van Loocke, The Physical Nature of Consciousness, 41). In that 1993 paper (which we offer separately) Lloyd's computer architecture, every â??quit', or gate, does not need to be addressed individually. Lloyd's architecture necessitates "only a few control quits are needed, while the quantum information is stored in a chain of quits that consists of repeated units ABC of only three distinguishable physical qubits. Each group of three physical quits stores one logical quit. Logical operations can be broken down into operations that act on all A, B or C physical quits. It was shown that this architecture is universal, i.e., it can efficiently run all algorithms that are efficient on a network quantum computer" (Stolze, Quantum Computing, 143). In this 1996 paper, Lloyd goes further. Feynman had essentially asked whether implicit exponential explosion might be bypassed by "having one quantum system simulate another directly so that the states of the simulator obey the same equations of motion as the states of the simulated system. [In 1996, Lloyd shows] that a variety of quantum systems, including quantum computers, can be â??programmed' to simulate the behavior of arbitrary quantum systems whose dynamics are determined by local interactions. The programming is accomplished by inducing interactions between the variables of the simulator that imitate the interactions between the variables of the system to be simulated. In effect, the dynamics of the properly programmed simulator and the dynamics of the system to be simulated are one and the same to within any desired accuracy" (Lloyd, 1996, p. 1073).

It was shown that this architecture is universal, i.e., it can efficiently run all algorithms that are efficient on a network quantum computer" (Stolze, Quantum Computing, 143). Lloyd argues that "operated with frequent error correction, such a system functions as a parallel digital computer. Operated in a quantum-mechanically coherent manner, such a device functions as a general purpose quantum-mechanical micro-manipulator, capable of both creating any desired quantum state of the array and transforming that state in any desired way" (Lloyd, 1993, p. 1569).
