Decoy-state quantum key distribution with biased basis choice
Decoy-state quantum distribution biased basis choice
2016/1/23
Quantum key distribution (QKD) utilizes the laws of quantum mechanics to achieve information-theoretically secure key generation. This field is now approaching the stage of commercialization, but many...
Convergence of many-body wavefunction expansions using a plane wave basis: from the homogeneous electron gas to the solid state
Convergence many-body wavefunction expansions plane wave basis homogeneous electron gas solid state
2012/2/29
Using the finite simulation-cell homogeneous electron gas (HEG) as a model, we investigate the convergence of the correlation energy to the complete basis set (CBS) limit in methods utilising plane-wa...

We demonstrate that the two-dimensional AKLT state on a honeycomb lattice is a universal
resource for measurement-based quantum computation. Our argument proceeds by reduction of
the AKLT state to a...

Given a pure state vector |xi and a density matrix ˆρ, the function p(x|ˆρ) = hx|ˆρ|xi defines a probability density on the space of pure states parameterised by density matrices. The a...

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...
