Quantum Computation under Micromotion in a Planar Ion Crystal
Quantum Computation Micromotion Planar Ion Crystal
2016/1/22
We propose a scheme to realize scalable quantum computation in a planar ion crystal confined by a Paul trap. We show that the inevitable in-plane micromotion affects the gate design via three separate...

In classical computation, a "write-only memory" (WOM) is little more than an oxymoron, and the addition of WOM to a (deterministic or probabilistic) classical computer brings no advantage. We prove th...
In order to investigate distributed quantum computation under restricted network resources, we introduce a quantum computation task over the butterfly network where both quantum and classical communic...

Non-adaptive Measurement-based Quantum Computation Multi-party Bell Inequalities
2010/10/21
Quantum correlations exhibit behaviour that cannot be resolved with a local hidden variable picture of the world. In quantum information, they are also used as resources for information processing tas...
We propose a method for the measurement-based blind quantum computation with Affleck-Kennedy-Lieb-Tasaki (AKLT) chains. Alice, a client, prepares certain quantum states which conceal
some secret info...
Neuromorphic, Digital and Quantum Computation with Memory Circuit Elements

Memory effects are ubiquitous in nature and the class of memory circuit elements - which includes memristors,memcapacitors and meminductors - shows great potential to understand and simulate the assoc...

Ground-state geometric quantum computation superconducting systems
2010/10/19
We propose a way to implement geometric quantum computation based on a Hamiltonian which
has a doubly degenerate ground state. Thus the system, which is steered adiabatically, remains
in the instant...
Strong entanglement causes low gate fidelity in inaccurate one-way quantum computation
one-way quantum computation Strong entanglement low gate fidelity
2010/3/10
We study how entanglement among the register qubits affects the gate fidelity in the one-way quantum computation if a measurement is inaccurate. We show that the mean gate fidelity is upper bounded by...

Quantum Computation Anharmonic Linear Ion Trap
2010/4/7
We propose a large-scale quantum computer architecture by stabilizing a single large linear ion chain in a very simple trap geometry. By confining ions in an anharmonic linear trap with nearly uniform...

2010/4/7
We study the use of the quantum wavelet transform to extract efficiently information about the multifractal exponents for multifractal quantum states. We show that, combined with quantum simulation al...

We present a strategy to engineer a simple cavity-QED two-bit universal quantum gate using

We give a quantum algorithm for solving instances of the satisfiability problem, based on adiabatic evolution. The evolution of the quantum state is governed by a time-dependent Hamiltonian that inter...
New strategy for suppressing decoherence in quantum computation
New strategy suppressing decoherence quantum computation
2010/10/13
Controlable strong interaction of the qubit’s bath with an external system(i.e. with the bath’s environment) allows for choosing the conditions under which the decoherence of the qubit’s states can be...
