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...

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...
