This book provides a thorough introduction to quantum information theory and quantum computation in general, especially covering the theoretical and computational, rather than experimental, aspects of these fields. The particular strengths of the volume are: the completeness of both basic and more advanced aspects of quantum computation and theory… (More)
The assumption of maximum parallelism support for the successful realization of scalable quantum computers has led to homogeneous, "sea-of-qubits" architectures. The resulting architectures overcome the primary challenges of reliability and scalability at the cost of physically unacceptable system area. We find that by exploiting the natural serialization… (More)
Compilers and computer-aided design tools are essential for fine-grained control of nanoscale quantum-mechanical systems. A proposed four-phase design flow assists with computations by transforming a quantum algorithm from a high-level language program into precisely scheduled physical actions.
The number of steps any classical computer requires in order to find the prime factors of an l-digit integer N increases exponentially with l, at least using algorithms known at present. Factoring large integers is therefore conjectured to be intractable classically, an observation underlying the security of widely used cryptographic codes. Quantum… (More)
Decoherence in quantum computers is formulated within the semigroup approach. The error generators are identified with the generators of a Lie algebra. This allows for a comprehensive description which includes as a special case the frequently assumed spin-boson model. A generic condition is presented for errorless quantum computation: decoherence-free… (More)
Fifty years of developments in nuclear magnetic resonance sNMRd have resulted in an unrivaled degree of control of the dynamics of coupled two-level quantum systems. This coherent control of nuclear spin dynamics has recently been taken to a new level, motivated by the interest in quantum information processing. NMR has been the workhorse for the… (More)
Irrespective of the underlying technology used to implement a large-scale quantum architecture system, one of the central challenges of accurately modeling the architecture is the ability to map and schedule a quantum application onto a physical grid while taking into account the cost of communication, the classical resources, and the maximum exploitable… (More)
As process technologies decrease in feature size, designers face new reliability challenges. Feature sizes of less than 0.25 /spl mu/m increase the risk of noise-related faults that result from electrical disturbances in the logic values held in circuits and on wires. Such transient faults can cause single-bit upsets, which in turn can introduce a logical… (More)
Student-participation data from the inaugural MITx (now edX) course---6.002x: Circuits and Electronics---unpacks MOOC student behavior.
