Coherence of single spins coupled to a nuclear spin bath of varying density
N. Mizuochi, P. Neumann, F. Rempp +9
The dynamics of single electron and nuclear spins in a diamond lattice with different 13C nuclear spin concentration is investigated. It is shown that coherent control of up to thr…
Erasing Distinguishability Using Quantum Frequency Up-Conversion
Hiroki Takesue
The frequency distinguishability of two single photons was successfully erased using single photon frequency up-conversion. A frequency non-degenerate photon pair generated via spo…
Towards a unified approach to information-disturbance tradeoffs in quantum measurements
Francesco Buscemi, Michal Horodecki
We show that the global balance of information dynamics for general quantum measurements given in [F. Buscemi, M. Hayashi, and M. Horodecki, Phys.Rev.Lett. 100, 210504 (2008)] make…
Oracularization and Two-Prover One-Round Interactive Proofs against Nonlocal Strategies
Tsuyoshi Ito, Hirotada Kobayashi, Keiji Matsumoto
A central problem in quantum computational complexity is how to prevent entanglement-assisted cheating in multi-prover interactive proof systems. It is well-known that the standard…
Wavelength-Multiplexed Entanglement Distribution over 10 km of Fiber
Han Chuen Lim, Akio Yoshizawa, Hidemi Tsuchida +1
We report the first experimental demonstration of wavelength-multiplexed entanglement distribution. 44 channels of highly-entangled photon-pairs from one single broadband source ar…
Coupling strength estimation for spin chains despite restricted access
Daniel Burgarth, Koji Maruyama, Franco Nori
Quantum control requires full knowledge of the system many-body Hamiltonian. In many cases this information is not directly available due to restricted access to the system. Here w…
