Numerical simulations of mixed states quantum computation
We describe quantum-octave package of functions useful for simulations of quantum algorithms and protocols. Presented package allows to perform simulations with mixed states. We present numerical implementation of important quantum mechanical operations – partial trace and partial transpose. Those operations are used as building blocks of algorithms for analysis of entanglement and quantum erro...
متن کاملCluster-state Quantum Computation
This article is a short introduction to and review of the cluster-state model of quantum computation, in which coherent quantum information processing is accomplished via a sequence of single-qubit measurements applied to a fixed quantum state known as a cluster state. We also discuss a few novel properties of the model, including a proof that the cluster state cannot occur as the exact ground ...
متن کاملNumerical Simulations of Quantum Phase Transitions
In this talk I will describe some examples of quantum phase transitions with disorder and explain in what ways these transitions diier from conventional phase transitions at nite temperature. It will be explained that the-expansion does not work and so much of what we know has come from numerical simulations. A novel feature is the importance of \Griiths singularities", which come from rare, st...

متن کاملImproved constructions of mixed state quantum automata
Quantum finite automata with mixed states are proved to be super-exponentially more concise rather than quantum finite automata with pure states. It was proved earlier by A. Ambainis and R. Freivalds that quantum finite automata with pure states can have an exponentially smaller number of states than deterministic finite automata recognizing the same language. There was an unpublished ‘‘folk th...
