Two Local Observables are Sufficient to Characterize Maximally Entangled States of N Qubits
Fengli Yan, Ting Gao, Eric Chitambar
Maximally entangled states (MES) represent a valuable resource in quantum information processing. In -qubit systems the MES are -GHZ states, i.e. the collection of $\ket{GHZ_…
Insecurity of position-based quantum cryptography protocols against entanglement attacks
Hoi Kwan Lau, Hoi Kwong Lo
Recently, position-based quantum cryptography has been claimed to be unconditionally secure. In contrary, here we show that the existing proposals for position-based quantum crypto…
Passive sources for the Bennett-Brassard 1984 quantum key distribution protocol with practical signals
Marcos Curty, Xiongfeng Ma, Hoi-Kwong Lo +1
Most experimental realizations of quantum key distribution are based on the Bennett-Brassard 1984 (so-called BB84) protocol. In a typical optical implementation of this scheme, the…
Experimental characterization of qutrits using SIC-POVMs
Z. E. D. Medendorp, F. A. Torres-Ruiz, L. K. Shalm +3
Generalized quantum measurements (also known as POVMs) are of great importance in quantum information and quantum foundations, but often difficult to perform. We present an experim…
Closed timelike curves via post-selection: theory and experimental demonstration
Seth Lloyd, Lorenzo Maccone, Raul Garcia-Patron +8
Closed timelike curves (CTCs) are trajectories in spacetime that effectively travel backwards in time: a test particle following a CTC can in principle interact with its former sel…
Detecting Multipartite Classical States and their Resemblances
Lin Chen, Eric Chitambar, Kavan Modi +1
We study various types of multipartite states lying near the quantum-classical boundary. The class of so-called classical states are precisely those in which each party can perform…
