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...
Large Scale Quantum Computation in an Anharmonic Linear Ion Trap
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...
Quantum computation of multifractal exponents through the quantum wavelet transform
Quantum computation multifractal exponents quantum wavelet transform
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...
Quantum computation with mesoscopic superposition states
Quantum mesoscopic superposition states

We present a strategy to engineer a simple cavity-QED two-bit universal quantum gate using
mesoscopic distinct quantum superposition states. The dissipative effect on decoherence and amplitude dampin...
