Decoherence Bounds on Quantum Computation with Trapped Ions.
نویسندگان
چکیده
Using simple physical arguments we investigate the capabilities of a quantum computer based on cold trapped ions. From the limitations imposed on such a device by spontaneous decay, laser phase coherence, ion heating, and other sources of error, we derive a bound between the number of laser interactions and the number of ions that may be used. The largest number which may be factored using a variety of species of ion is determined. [S0031-9007(96)01181-7]

Quantum computing with four-particle decoherence-free states in an ion trap
Much effort has been put into quantum computing over the past few years due to great advantages of quantum computing over the computation made in existing computers for solving classically intractable problems @1,2# and finding tractable solutions more rapidly @3#. Some systems @4# such as nuclear magnetic resonance, trapped ions, cavity quantum electrodynamics, and optical photons have been pr...
متن کاملDecoherence limits to quantum computation using trapped ions
We investigate the problem of factorization of large numbers on a quantum computer which we imagine to be realized within a linear ion trap. We derive upper bounds on the size of the numbers that can be factorized on such a quantum computer. These upper bounds are independent of the power of the applied laser. We investigate two possible ways to implement qubits, in metastable optical transitio...
متن کاملHolonomic quantum computation in decoherence-free subspaces.
We show how to realize, by means of non-Abelian quantum holonomies, a set of universal quantum gates acting on decoherence-free subspaces and subsystems. In this manner we bring together the quantum coherence stabilization virtues of decoherence-free subspaces and the fault tolerance of all-geometric holonomic control. We discuss the implementation of this scheme in the context of quantum infor...
متن کاملExperimental Issues in Coherent Quantum-State Manipulation of Trapped Atomic Ions
Methods for, and limitations to, the generation of entangled states of trapped atomic ions are examined. As much as possible, state manipulations are described in terms of quantum logic operations since the conditional dynamics implicit in quantum logic is central to the creation of entanglement. Keeping with current interest, some experimental issues in the proposal for trappedion quantum comp...
متن کاملRecent results in trapped-ion quantum computing at NIST
We review recent experiments on entanglement, Bell's inequality , and decoherence-free subspaces in a quantum register of trapped 9 Be + ions. We have demonstrated entangle-ment of up to four ions [1] using the technique of Mølmer and Sørensen [2]. This method produces the state (|↑↑+|↓↓)/ √ 2 for two ions and the state (| ↓↓↓↓ + | ↑↑↑↑)/ √ 2 for four ions. We generate the entanglement determin...
