Quantum random sampling is the leading proposal for demonstrating a computational
advantage of quantum computers over classical computers. Recently the first large-scale …

Recent years have seen significant advances in the study of symmetric informationally
complete (SIC) quantum measurements, also known as maximal sets of complex …

We present a quantum key distribution system with a 2.5 GHz repetition rate using a three-
state time-bin protocol combined with a one-decoy approach. Taking advantage of …

Although complex numbers are essential in mathematics, they are not needed to describe
physical experiments, as those are expressed in terms of probabilities, hence real numbers …

Quantum theory is commonly formulated in complex Hilbert spaces. However, the question
of whether complex numbers need to be given a fundamental role in the theory has been …

The twin-field quantum key distribution (TFQKD) protocol and its variants, eg, phase-
matching (PM) QKD and TFQKD based on sending or not sending, are highly attractive …

Because of conservation of energy we cannot directly turn a quantum system with a definite
energy into a superposition of different energies. However, if we have access to an …

The CRC Handbook of Finite Fields (hereafter referred to as the Handbook) is a reference
book for the theory and applications of finite fields. It is not intended to be an introductory …

'Der Kopf, so gesehen, hat mit dem Kopf, so gesehen, auch nicht die leiseste Ahnlichkeit (...)
Der Aspektwechsel.“Du würdest doch sagen, dass sich das Bild jetzt gänzlich geändert hat!” …

This largely self-contained book on the theory of quantum information focuses on precise
mathematical formulations and proofs of fundamental facts that form the foundation of the …
