Scalable computation of thermomechanical turbomachinery problems

Scalable NMR Quantum Computation

Nuclear magnetic resonance offers an appealing prospect for implementation of quantum computers, because of the long coherence times associated with nuclear spins, and extensive laboratory experience in manipulating the spins with radio frequency pulses. Existing proposals, however, suffer from a signal-to-noise ratio that decays exponentially in the number of qubits in the quantum computer. Th...

Scalable Secure Multiparty Computation

We present the first general protocol for secure multiparty computation which is scalable, in the sense that the amortized work per player does not grow, and in some natural settings even vanishes, with the number of players. Our protocol is secure against an active adversary which may adaptively corrupt up to some constant fraction of the players. The protocol can be implemented in a constant ...

Scalable Human-based Computation

Human computation is becoming an essential component of many computer systems architectures, resulting in what can be referred to as Human-Machine Systems. In order to foster this adoption, the Human computation component should deliver close to predictable performance, both in terms of speed and quality. My dissertation work aims at addressing some of the current shortcomings of paid micro-tas...

Scalable Hybrid Computation with Spikes

We outline a hybrid analog-digital scheme for computing with three important features that enable it to scale to systems of large complexity: First, like digital computation, which uses several one-bit precise logical units to collectively compute a precise answer to a computation, the hybrid scheme uses several moderate-precision analog units to collectively compute a precise answer to a compu...
