We prove a fundamental theorem about the relative entropy of quantum states, which roughly states that if the relative entropy, S(/spl rho//spl par//spl sigma/)/spl Delta/=Tr /spl rho/(log /spl rho/-log /spl sigma/), of two quantum states /spl rho/ and /spl sigma/ is at most c, then /spl rho//2/sup O(c)/ 'sits inside' /spl sigma/. Using this 'substate' theorem, we give tight lower ...

Summary form only given. Our understanding of the physical world at the most fundamental level is based on two theories: quantum theory and general relativity. They are impressively successful but only when each is considered on its own. In situations where both play a role, we are reduced to puzzles and absurdity. Hence the search for a quantum theory of ...

The relative entropy of two distributions of n random variables, and more generally of two n-party quantum states, is an important quantity exhibiting, for example, the extent to which the two distributions/states are different. The relative entropy of the states formed by restricting to a smaller number m of parties is always less than or equal to the relative entropy ...

As device structures get smaller quantum mechanical effects predominate. About twenty years ago it was shown that it was possible to redesign devices so that they could still carry out the same functions. Recently it has been shown that the processing speed of computers based on quantum mechanics is indeed far superior to their classical counterparts for some important applications. ...

We prove a fundamental theorem about the relative entropy of quantum states, which roughly states that if the relative entropy, S(/spl rho//spl par//spl sigma/)/spl Delta/=Tr /spl rho/(log /spl rho/-log /spl sigma/), of two quantum states /spl rho/ and /spl sigma/ is at most c, then /spl rho//2/sup O(c)/ 'sits inside' /spl sigma/. Using this 'substate' theorem, we give tight lower bounds for the privacy loss of bounded error quantum communication protocols for the index function problem. We also use the 'substate' theorem to give tight lower bounds for the k-round bounded error quantum communication complexity of the pointer chasing problem, when the wrong player starts, and all the log n bits of the kth pointer are desired.
Summary form only given. Our understanding of the physical world at the most fundamental level is based on two theories: quantum theory and general relativity. They are impressively successful but only when each is considered on its own. In situations where both play a role, we are reduced to puzzles and absurdity. Hence the search for a quantum theory of gravity, the currently missing theory that will work sensibly in exactly these situations. To the great frustration of researchers in this field, candidate quantum theories of gravity tend to produce more puzzles instead of answers. We shall take a tour of some of the problems, focusing on the role of spacetime and causality. Finally, we shall see how one can create a spacetime from a world with no notion of "here" and "there".
The relative entropy of two distributions of n random variables, and more generally of two n-party quantum states, is an important quantity exhibiting, for example, the extent to which the two distributions/states are different. The relative entropy of the states formed by restricting to a smaller number m of parties is always less than or equal to the relative entropy of the two original n-party states. This is the monotonicity of relative entropy. Using techniques from convex geometry, we prove that monotonicity under restrictions is the only general inequality satisfied by relative entropies. In doing so we make a connection to secret sharing schemes with general access structures: indeed, it turns out that the extremal rays of the cone defined by monotonicity are populated by classical secret sharing schemes. A surprising outcome is that the structure of allowed relative entropy values of subsets of multiparty states is much simpler than the structure of allowed entropy values. And the structure of allowed relative entropy values (unlike that of entropies) is the same for classical probability distributions and quantum states
As device structures get smaller quantum mechanical effects predominate. About twenty years ago it was shown that it was possible to redesign devices so that they could still carry out the same functions. Recently it has been shown that the processing speed of computers based on quantum mechanics is indeed far superior to their classical counterparts for some important applications. This paper introduces quantum mechanics and shows how this can be used for computation.
Using the worldline path integral quantization framework in quantum field theory we construct a generating functional for a relativistic particle's quantum-average trajectory. The approach systematically generalizes to incorporate quantum corrections (to the average) and quantum fluctuations (around the average).
The ability to predict the nature of physics in great detail depends upon the ultimate capabilities of information processing systems. Computing must be carried out in real systems, subject to physical laws. Thus an intertwining between the ultimate versions of the laws of physics and the computer is created. In order to satisfy this ``want ad'' for a unified theory, two conditions must be met: The type of information processing required in the study of physics must be recognized; and the physical laws governing information processing must be defined.
Summary form only given. In quantum mechanics, if two or more perturbations induce a transition between the same initial and final states of system, the overall transition probability is determined by the modulus squared of the sum of the transition amplitudes for each perturbation. It is therefore possible for interference effects to determine the outcome as it does in the classical Young's double slit experiment. If two coherent beams with frequencies /spl omega/ and 2/spl omega/ are applied to a system, the interference between the quantum mechanical pathways associated with single and two photon absorption events can lead to final states on the system whose properties are dependent on the relative phase of the beams.<<ETX>>
Cosmic Journeys is a new series of NASA space science missions housed within the Structure and Evolution of the Universe science theme. The central goal of the Cosmic Journeys missions is to solve the mystery of gravity, a fundamental force that is all around us but about which very little is known. Cosmic Journeys will use the power of resolution far greater than what current telescopes can muster to virtually transport us to regions in space and time where gravity is most compelling: at the rim of a black hole, across galaxy clusters and voids that pervade the Universe, and at the moment after the Big Bang when the four fundamental forces may have been intertwined. Cosmic Journeys will have a fleet of orbiting observatories at its command capturing the full range of the electromagnetic spectrum. The NASA Journeys program is also forging a partnership with the National Science Foundation (NSF) and the Department of Energy (DOE), called "Connections: From Quarks to the Cosmos," with hopes of bringing together physicists, astronomers and other professionals who have traditionally worked independently. Together, the three agencies will fund a variety of ground- and space-based research.
There is increasing evidence that information may be the basic stuff of the universe. We consider this proposition in the light of Bohm and Hiley's (1993) quantum potential, the work of the ANPA group on the combinatorial hierarchy, and the natural philosophies of G. Kron (1963) and M. Jessel (1962). We compare and contrast the philosophical backgrounds of both these and the more conventional Copenhagen interpretation. In conclusion, we suggest that our approach should be termed 'constructive postmodern physics'.<<ETX>>
