We propose and experimentally demonstrate a new scheme for measuring high-dimensional phase states using a two-photon interference technique, which we refer to as quantum-controlled measurement. Using this scheme, we implement a $d$-dimensional time-phase quantum key distribution (QKD) system and achieve secret key rates of 5.26 and 8.65 Mbps using $d = 2$ and $d = 8$ quantum states, respectively, for a 4~dB channel loss, illustrating that high-dimensional time-phase QKD protocols are…

High-Rate Field Demonstration of Large-Alphabet Quantum Key Distribution
A quantum key distribution protocol is introduced that uses high dimensional temporal encoding to boost the secret-key rate by increasing the secure information yield per detected photon, and this demonstrates a new, practical way to optimize secret- key rates.
On quantum information
This work investigates the following generalisation of the entropy of quantum measurement and gives a general form of generalised information I.
A new language, Opt, is proposed for writing these objective functions over image- or graph-structured unknowns concisely and at a high level and automatically transforms these specifications into state-of-the-art GPU solvers based on Gauss-Newton or Levenberg-Marquardt methods.
Hypothetical Stars. (Abstract) Recent determinations of the photovisual magnitudes of com-parison stars in the globular cluster Messier 3 permit a statistical discussion of the relative absolute
A prototype probability package named APPL (A Probability Programming Language) is presented that can be used to manipulate random variables and examples illustrate its use.
Apesar da gestão de carreiras ser uma preocupação recente no quadro da gestão das relações de trabalho, é hoje evidente a crise em que se encontra a forma tradicional de abordagem desta problemática.
