Higher Order Methods for Simulations on Quantum Computers
To efficiently implement many-qubit gates for use in quantum simulations on quantum computers we develop and present methods reexpressing exp[−i(H1 + H2 + . . .)∆t] as a product of factors exp[−iH1∆t], exp[−iH2∆t], . . . which is accurate to 3rd or 4th order in ∆t. The methods we derive are an extended form of symplectic method and can also be used for the integration of classical Hamiltonians ...

متن کاملLocal Search Methods for Quantum Computers
Local search algorithms use the neighborhood relations among search states and often perform well for a variety of NP-hard combinatorial search problems. This paper shows how quantum computers can also use these neighborhood relations. An example of such a local quantum search is evaluated empirically for the satisfiability (SAT) problem and shown to be particularly effective for highly constra...
متن کاملComputational Methods for Simulating Quantum Computers
This review gives a survey of numerical algorithms and software to simulate quantum computers. It covers the basic concepts of quantum computation and quantum algorithms and includes a few examples that illustrate the use of simulation software for ideal and physical models of quantum computers.
متن کاملPolynomial Simulations of Decohered Quantum Computers
Recently it has become clear, that a key issue in quantum computation is understanding how interaction with the environment, or \decoherence", e ects the computational power of quantum computers. We adopt the standard physical method of describing systems which are interwound with their environment by \density matrices", and within this framework de ne a model of decoherence in quantum computat...
