Symmetric collective attacks for the eavesdropping of symmetric quantum key distribution
Stefano Pirandola
We consider the collective eavesdropping of the BB84 and six-state protocols. Since these protocols are symmetric in the eigenstates of conjugate bases, we consider collective atta…
Quantum Computation Beyond the Circuit Model
Stephen P. Jordan
The quantum circuit model is the most widely used model of quantum computation. It provides both a framework for formulating quantum algorithms and an architecture for the physical…
Heralded single-magnon quantum memory for photon polarization states
Haruka Tanji, Saikat Ghosh, Jonathan Simon +2
We demonstrate a heralded quantum memory based on mapping of a photon polarization state onto a single collective-spin excitation (magnon) shared between two spatially overlapped a…
Experimental entanglement distillation using Schmidt projection on multiple qubits
Taehyun Kim, Franco N. C. Wong
Entanglement distillation is a procedure for extracting from one or more pairs of entangled qubits a smaller number of pairs with a higher degree of entanglement that is essential…
Computable bounds for the discrimination of Gaussian states
Stefano Pirandola, Seth Lloyd
By combining the Minkowski inequality and the quantum Chernoff bound, we derive easy-to-compute upper bounds for the error probability affecting the optimal discrimination of Gauss…
Quantum theory of optical temporal phase and instantaneous frequency
Mankei Tsang, Jeffrey H. Shapiro, Seth Lloyd
We propose a general quantum theory of optical phase and instantaneous frequency in the time domain for slowly varying optical signals. Guided by classical estimation theory, we de…
