Source attack of decoy-state quantum key distribution using phase information
Source attack decoy-state quantum key distribution phase information
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...
Optimal design and quantum benchmarks for coherent state amplifiers
Optimal design quantum benchmarks coherent state amplifiers
2016/1/23
We establish the ultimate quantum limits to the amplification of an unknown coherent state, both in the deterministic and probabilistic case, investigating the realistic scenario where the expected ph...
Creation of NOON states by double Fock-state/Bose-Einstein condensates
State of single particle state variable theory the measuring accuracy measuring phase the condensate
2014/12/19
NOON states (states of the form |N〉 a |0〉 b +|0〉 a |N〉 b where a and b are single particle states) have been used for predicting violations of hidden-variable theories (Greenbe...
On the Quantum Mechanical State of the $\Delta^{++}$ baryon
the Quantum Mechanical State Physics
2010/11/16
The $\Delta^{++}$ and the $\Omega^-$ baryons have been used as the original reason for the construction of the Quantum Chromodynamics theory of Strong Interactions. The present analysis relies on the...
Passive scheme with a photon-number-resolving detector for decoy-state quantum key distribution with an untrusted source
photon-number-resolving decoy-state quantum
2010/3/10
A passive scheme with a photon-number-resolving (PNR) detector and a beam splitter which are used to monitor the statistical characteristics of photon source, is proposed to verify the security of vac...
Decoherence as a signature of an excited state quantum phase transition
Decoherence excited state quantum phase transition
2010/3/10
We analyze the decoherence induced on a single qubit by the interaction with a two-level boson system with critical internal dynamics. We explore how the decoherence process is affected by the presenc...

Universal state observed by Australian physicists（图）
"universality" magnetic field superconductors
2007/7/6
19 June 2007，A team of Australian and Chinese scientists have found the first observed evidence for "universality" in a paper to be published in the prestigious Nature Physics journal next month.
I present a four-party unlockable bound-entangled state, that is, a four-party quantum state
which cannot be written in a separable form and from which no pure entanglement can be distilled by local ...
