Programming the universe : a quantum computer scientist takes on the cosmos by Seth Lloyd( Book )
20 editions published between 2006 and 2013 in English and held by 1,479 WorldCat member libraries worldwide
Is the universe actually a giant quantum computer? According to Seth Lloyd--professor of quantum-mechanical engineering at MIT and originator of the first technologically feasible design for a working quantum computer--the answer is yes. This book illuminates the professional and personal paths that led him to this remarkable conclusion. All interactions between particles in the universe, Lloyd explains, convey not only energy but also information--in other words, particles not only collide, they compute. And what is the entire universe computing, ultimately? "Its own dynamical evolution," he says. "As the computation proceeds, reality unfolds." To elucidate his theory, Lloyd examines the history of the cosmos, posing questions that in other hands might seem unfathomably complex: How much information is there in the universe? What information existed at the moment of the Big Bang and what happened to it? How do quantum mechanics and chaos theory interact to create our world? Could we attempt to re-create it on a giant quantum computer?--From publisher description
Battle of the brains ( Visual )

This programme sets out to test intelligence by avoiding the standard use of an IQ test. Seven people, highly successful in their different fields, are put through a series of different tests aimed to 'measure' their intellect. The framing of the documentary, including the narrator, is similar to those from a popular TV series called 'The Apprentice', where entrepreneurs are pitted against each other.Participants include Susan Polgar a champion chess player, Gerry Stratford a jet fighter pilot, Alex Prior a musical prodigy, Nathan Hasselbauer an IQ champion, Bonnie Greer a dramatist, Seth Lloyd a quantum physicist and Stella Vine an artist. Initially on the original standard IQ test the clear winners are Lloyd and Hasselbauer but as different kinds of tests are put to the participants it becomes clear that intelligence can take on many forms, over-looked by the IQ test. These include tests to measure practical intelligence, imaginative thinking, artistic or creative thinking and emotional intelligence. Throughout we hear the opinions of various intelligence researchers, some of whom design the tests the participants take part in. Robert Plomin, geneticist, comments on how surprisingly heredital intelligence is. The end results are surprising with a draw for first place between Seth Lloyd and Bonnie Greer. There is some interesting archive footage relating to IQ testing in Scotland in the 1930s and then follow-up tests more recently

Quantum Logic and Parallel Computing Using Spectral Holeburning Technologies ( )
2 editions published between 2001 and 2002 in English and held by 2 WorldCat member libraries worldwide
The objective of this project was to investigate the use of spectral holeburning technologies for quantum logic and parallel computing. To this end, we have made substantial progress on both experimental and theoretical fronts. In NV-diamond, we have demonstrated the alignment of spins, which can then be used as quantum bits for a quantum computer. We have performed high resolution imaging of color centers in NV-diamond, as a key step towards isolating and detecting individual quantum bits. We have also developed a detailed model for cavity induced coupling of qubits in this system. Furthermore, we have developed a concrete design for producing a photonic band gap based cavity directly in a diamond substrate. Such a cavity will have the requisite combination of high finesse and low loss necessary for photon-mediated coupling of qubits, which is not possible using bulk mirror cavities because of high surface reflection losses from an embedded crystal. We have also developed a novel model for cavity-induced coupling via the atom-cavity-dark-state, a process that is robust against atomic as well cavity decay. Finally, we have identified a mechanism for direct dipole-dipole coupling of the qubits as well. This scheme is particularly well suited for creating in parallel many quantum computers, each containing a small number of coupled qubits. Dubbed Type II Quantum Computing, this architecture is expected to outperform the best classical computers in specialized tasks such as modeling turbulence through the cellular automaton based lattice gas dynamics. In Pr:YSO, we have demonstrated a slowing (45 misec) and high-fidelity storage and recall of light pulses. This scheme is expected to enable the realization of a near-perfect quantum memory for single-photons, storing and recalling it with near 100% fidelity

Quantum Information and Computation (QUIC) ( )
1 edition published in 2001 in English and held by 1 WorldCat member library worldwide
A broad, multidisciplinary program has been pursued in the area of quantum computation and information. Principal accomplishments include an experiment to localize atoms within a high quality factor optical cavity for the implementation of quantum logic and the realization of quantum teleportation. Theoretical work has shown how to accomplish quantum computations of arbitrary length reliably, even with error prone quantum gates and memories, and has significantly improved calculations of the required error thresholds. Quantum error correction has been analyzed within the larger framework of quantum feedback control. New types of physical systems have been investigated for quantum computation that would be intrinsically robust to environmental disturbances. Bridges between experiment and theory have been built by way of large-scale simulations of quantum circuits on classical computers, including quantum Monte Carlo techniques. These simulations allow for detailed investigations of the impact of errors and allow for validation of various models of actual physical systems. New algorithms have been developed for simple (few-bit) quantum computers. Diverse 'nonstandard' models for quantum computation have been investigated, including nonlinear quantum mechanics for quantum computation

Quantum Computation With Mesoscopic Superconducting Devices ( )
1 edition published in 2002 in English and held by 1 WorldCat member library worldwide
The goal of this research was to explore the use of superconducting circuits as components for quantum computing Quantum computers are devices that store information on quantum variables and process that information by making those variables interact in a way that preserves quantum coherence. Typically, these variables consist of two quantum states, and the quantum device is called a quantum bit or qubit Superconducting quantum circuits have been proposed as qubits, in which circulating currents of opposite polarity characterize the two quantum states. Recent experiments show that these two macroscopic quantum states can be put into a superposition. In particular, microwave spectroscopy experiments indicate symmetric and anti-symmetric quantum superpositions of macroscopic states

Human version 2.0 ( Visual )

This documentary asks if we are on the verge of creating a super human, an amalgamation of biology and technology, through which we can change the nature of what it is to be human forever. This moment is known among scientists as the 'singularity.' Experts from the fields of biology, science and technology give their opinions about this future possibility, but many remain sceptical and fearful of the interface between biology and technology becoming too fused. John Chapin has already created a remote controlled rat - a real rat who can be controlled by a computer. Miguel Nicolelis has been decoding the mind of a monkey with electrodes dropped into its brain which he is attempting to translate into the movement of a mechanical arm. Eric Ramsey is a teenager trapped in a 'locked in' state following a car accident - Philip Kennedy has linked his mind to a computer in an attempt to translate his thoughts into words spoken by the computer. We hear the story of the una-bomber, a man who wanted to derail technology, and Seth Lloyd who is attempting to translate the sounds of atoms

"What is the universe made of? The conventional view states that it is made up of matter and energy, of fields and elementary particles. But there is a more fundamental view: universe is made up of information, and at the bottom, it is made up of bits. Drawing from recently developed theories of quantum computation, we show how information and information processing form and shape the universe, from its smallest to its largest scales.

Quantum Computing and Optical Memory Using Spectral-Holeburning Techniques ( )
1 edition published in 2000 in English and held by 1 WorldCat member library worldwide
The equipment purchased under this DURIP grant has been used in our project for studying spectral hole burning materials for applications to quantum computing as well as optical memory, using spin coherence excited and controlled by two-photon Raman transitions. The key objective was to demonstrate that NV-Diamond color centers, which has a strong oscillator strength, is suitable for this process. Recently, we have observed efficient Raman transitions, which is manifested as electromagnetically induced transparency, in NV-diamond. Specifically, we have observed near perfect alignment of spin-based quantum bits, and performed single-qubit operations on collections of these qubits. The next step is to realize CNOT operations between spectrally adjacent, distinct quantum bits in this material. The robust nature of Raman excited spin transitions in NV diamond also establishes it as a viable candidate for ultra-high-density optical memory. Finally, we have also demonstrated recently that the optically excited spin coherence produces ultra-high non-linearity, resulting in slowing the velocity of light pulses down to 45 m/sec. The equipment obtained under this DURIP has been critical to these observations. in the near future, we will expand on this work as we try to realize a many bit quantum computer, as well as a high-temperature optical memory system based on spectral-hole-burning

"Is the universe a giant computer? If so, how does it compute? It has been known since the nineteenth century that every atom in the universe carries with it bits of information, and that every time two atoms collide, those bits flip. The universe is carrying out a computation at the most microscopic level. This talk discusses the implications of the computing universe, ranging from quantum computation and quantum gravity, to the problem of free will and the ultimate future of life.
