Quantitative Inference in a Mechanical Design Compiler
(1989-01-01)This paper presents the ideas underlying a program that takes as input a schematic of a mechanical or hydraulic power transmission system, plus specifications and a utility function, and returns catalog numbers from ...

Quantitative Information Flow as Network Flow Capacity
(2007-12-10)We present a new technique for determining how much information abouta program's secret inputs is revealed by its public outputs. Incontrast to previous techniques based on reachability from secretinputs (tainting), it ...

Quantitative Information-Flow Tracking for C and Related Languages
(2006-11-17)We present a new approach for tracking programs' use of data througharbitrary calculations, to determine how much information about secretinputs is revealed by public outputs. Using a fine-grained dynamicbit-tracking ...

Quantized Skyrmions from SU(4) weight diagrams
(Physical Review C, 2018-03-06)© 2018 authors. Published by the American Physical Society. Starting from solutions of the lightly bound Skyrme model, we construct many new Skyrmion solutions of the standard Skyrme model with tetrahedral or octahedral ...

Quantum communication complexity advantage implies violation of a Bell inequality
(National Academy of SciencesProceedings of the National Academy of Sciences, 2016-03-08)We obtain a general connection between a large quantum advantage in communication complexity and Bell non-locality. We show that given any protocol offering a sufficiently large quantum advantage in communication complexity, ...

Quantum Conditional Mutual Information, Reconstructed States, and State Redistribution
(APSPhysical Review Letters, 2015-06-29)We give two strengthenings of an inequality for the quantum conditional mutual information of a tripartite quantum state recently proved by Fawzi and Renner, connecting it with the ability to reconstruct the state from its ...

Quantum conditional query complexity
(Rinton PressQuantum Information and Computationhttp://www.rintonpress.com/journals/qicabstracts/qicabstracts17-78.html, 2017-06-01)We define and study a new type of quantum oracle, the quantum conditional oracle, which provides oracle access to the conditional probabilities associated with an underlying distribution. Amongst other properties, we (a) ...

Quantum information, Bell inequalities and the no-signalling principle
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2014-02-04)This PhD thesis contains a general introduction and three main chapters. Chapter 2 investigates Bell inequalities that generalize the CHSH and Braunstein-Caves inequalities. Chapter 3 shows a derivation of an upper bound ...

Quantum reality via late-time photodetection
(APSPhysical Review A, 2017-12-18)We further investigate postulates for realist versions of r elativistic quantum theory and quantum field theory in Minkowski space and other background space-t imes. According to these postulates, quantum theory is ...

Quantum Simulation Of A Transverse-Field Ising Model
(2010-12-15)A popular model that have been used to study ferromagnetism is the Ising Model which is an arrangement of spins along a particular direction and with discrete values of +1. 1-D Ising model doesn't show a phase transition ...

Quantum Stochastic Processes and Quantum Many-Body Physics
(University of CambridgeDAMTPSt John's College, 2017-10-04)This dissertation investigates the theory of quantum stochastic processes and its applications in quantum many-body physics. The main goal is to analyse complexity-theoretic aspects of both static and dynamic properties ...

Quantum theory from the perspective of general probabilistic theories
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2015-03-03)This thesis explores various perspectives on quantum phenomena, and how our understanding of these phenomena is informed by the study of general probabilistic theories. Particular attention is given to quantum nonlocality, ...

Quasi-cyclic behaviour in non-linear simulations of the shear dynamo
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2017-02-17)The solar magnetic field displays features on a wide range of length-scales including spatial and temporal coherence on scales considerably larger than the chaotic convection that generates the field. Explaining how the ...

Quasi-periodic oscillations and the global modes of relativistic, MHD accretion discs
The high-frequency quasi-periodic oscillations (HFQPOs) that punctuate the light curves of X-ray binary systems present a window onto the intrinsic properties of stellar-mass black holes and hence a testbed for general ...

Quaternionic Representation of the Riesz Pyramid for Video Magnification
(2014-04-26)Recently, we presented a new image pyramid, called the Riesz pyramid, that uses the Riesz transform to manipulate the phase in non-oriented sub-bands of an image sequence to produce real-time motion-magnified videos. In ...

Questioning the Mpemba effect: hot water does not cool more quickly than cold
(Nature Publishing GroupScientific Reports, 2016-11-24)The Mpemba effect is the name given to the assertion that it is quicker to cool water to a given temperature when the initial temperature is higher. This assertion seems counter-intuitive and yet references to the effect ...

Queueing Theory Analysis of Labor & Delivery at a Tertiary Care Center
(MIT CSAIL, 2014-12-16)Labor and Delivery is a complex clinical service requiring the support of highly trained healthcare professionals from Obstetrics, Anesthesiology, and Neonatology and the access to a finite set of valuable resources. In ...

A Quick Fail-Safe Procedure for Determining Whether the GCD of 2 Polynomials is 1
(1967-03-01)One of the most widely used routines in an algebraic manipulation system is a polynomial manipulation package (1,2,3). The crucial operation in such routines is the extraction of the Greatest Common Divisor (GCD) of ...

Quiver algebras as Fukaya categories
(Mathematical Sciences PublishersGeometry & Topology, 2015-10-20)We embed triangulated categories defined by quivers with potential arising from ideal triangulations of marked bordered surfaces into Fukaya categories of quasiprojective 3–folds associated to meromorphic quadratic ...
